- In this episode, we crunch the numbers to see which engine really gave us the biggest bang for the buck! Between our BluePrint 383 crate engine and our junkyard special LS, which one will come out on top? www.speedwaymotors.com/the-to...
All i can say is, Your engine builder has alot too learn about building small block Chevy's on a budget
For real. Also, it being short of 500hp for over $5k is kind of a joke.
same can be said about the LS
@@ScrapyardFights So what we're saying is, there's more to be desired here on both ends. The LS should make MUCH more for the same $.
Jeez, i spent mabye $1,700 on my little small block build & still hit close to 400 hp.
@@anthonycoffey816 stock ls engines make that though... also, ls engines will take more in terms of boost. I think theyre hitting 1500+ hp on the stock bottom end of the 5.3.
383 scat stroker kit internal balance from skip white double checked at machine shop…spot on. Mike Jones custom roller cam, 195 AFR heads, victor jr. fast fuel 750 cfm carb. 535 hp at 6300 all for less than 6 grand.
I got my BP 383 for 4200 shipped. Sniper efi with hyperspark ignition was about 1500. Makes about 460 hp and 500 torque, and had a 50,000 mile warranty. People sleep on that warranty, and is exactly why I went crate motor vs a local shop or hand built
@@OGfancy420where did you get your motor from? Sounds like a sick package!
@eeli808 blueprint engines, they went up in price a lot since I got my 383 but they have awesome products
Nice @@OGfancy420
Blue Print Motors@@eeli808
I just looked at the build sheets and the price includes a $600 power steering pump $800 headers $275 valve covers $300 starter $500 distributor for the SBC ....i think those expensive parts were not needed for comparison
Also how can a hydraulic flat tappet cam be compared to a hydraulic roller...I see all these SBC vs Ls comparisons but it's never equal making the Ls look so promising....yes the Ls has a better starting point with better flowing top end and roller cam and rockers
Just saw it too, there so full of shit. In the real world sbc is WAY cheaper than ls. No one in the right mind would pay $600 Just for a fucking power steering pump. Who ever made that list was just looking for the most overpriced crap they could possibly find.
@@grabacr1251 I don't know, LS cams/heads/fuel systems, cost basically the same as sbc cams/heads/fuel systems. The biggest price is resto-mods require an adaptation cost. Retromods do not.
change the intake to single plane
@@lssux4371 one of my friends has a ls2 in a 72 impala and my cousin has a blueprint 383 in a 71 caprice ... That 383 beats it from light to light ... Cant go wrong with old school
My 383 build using ported factory Vortec heads, which flow great, usually cost about $3,000 or less. I do my own machine work unless it needs to be bored so you can technically knock almost $500 off of that too. 7k for a 383!! You guys are out of your minds!
What carb you recommend I have a freshly built 383 with ported and polished vortec heads, 650?
@@shawnkennedy8425 There's not an easy answer to your question. It really depends on a lot of factors like your camshaft specs, weight of the vehicle, axle gear ratio, type of transmission being used, type of driving being done ( street, strip, 4x4 or towing), altitude it's being driven at, compression ratio, octane and type of fuel being used, gas mileage desired and how many RPM the engine is going to spin.
This will determine not only how many CFMs to have but which type / brand of carburetor to use.
A 650 CFM carb would work fine for most street driven applications but I would probably use a 700 or 750 for any kind of performance application.
If you give me more some more information I can get you my personal recommendation.
Would have been one of the greatest videos OFF ALL TIME had you ran each combo down the 1320 and had slips to back it up!!!! Food for thought!!!!
All that LQ9 needed was a cam, springs, headers, a couple of hp tuners credits and a few odds and ends from rock auto. $7700us wow. I must be watching horsepower tv....
Thanks much for uploading this video. I am contemplating putting a stroker motor into my 2003 GMC Sierra pickup.
Thanks for the video. have built cars and engines for over 40 years... and the LS can breathe so well that I wouldn't be surprised at all when the LS made gobs hp with a good cam honestly. What is surprising is the torque being a tad low on a 6.0 LS you could get more selective with the Cam and Recapture the lost torque. Thank you again, cool video.
Adding valve covers and a Holley carb added another 3k to the price of the 383. 😂😂
I like the classic look of the Stroker.
Great video BTW!
7 thousand dollars for a gen 1 383. You get all the LOL's for that. That's just crazy.
You spent the same amount of money on the basic bolt ons as you did on the complete long block? Were you intentionally trying to spend as much money as you could to make it look like a closer comparison?
were you using the same transmission? is it interchangeable with an easy kit? or you need different for each?
full engine: $78.
after unknown upgrades:$10,000
How are you spending 7k on the LS?? It has virtually everything you need except cam & headers...
Ross Templeton damn hooker headers got pricy
@@ThePoppyPlant I wouldnt spend the money on a Hooker
im sure the numbers were "adjusted: to make them seem a bit closer than they were. anyone that pays attention to modern day engines knows the LS is hands down better in every aspect. its the old school boomers that are still stuck on the past building gen 1 small blocks from 1955.
@@ScrapyardFights I love my small block to death (its a 383), wouldn't trade it for the world, but your right
@@ScrapyardFights Your right. I'm old school but I had a stock 96 Camaro lt1 that was bad ass and got 27 miles to the gallon. My 69 chevelle is mildly built but the newer engines are better. Even the v 6 engines now are faster than older engines. Technology rules
What cam grind went into that lq9?
At this point it comes down to witch one sounds the best lol both great engines
The 383 is just a more simple engine. Nothing like an old school SBC. But for boost, I’d go with the LS.
Valve float on the 383. That's how I read the dip around 5700.
Yep I agree, hydraulic cam is probably to blame
you think a flat tappet cam would be better?
@@user-tw6fb6yz4h Solid Roller gets the best of both worlds in a way depends on how cheap you want to build Flat tappet would be cheaper but solid roller gives you more hp/tq
It has a mild cam in it. They couldn't show you what they do with huge solid rollers and singleplane intakes, because then it would make the LS look weak.
My experience is the 383 can make the same power as the 6.0 but will not be as nice to drive around town. I built a 383 years ago to make 500hp the same as the 6.0, 500 with out accessories and open exhaust so more likely less in the vehicle. I had to get rid of the power brakes because there wasn't enough manifold vacuum to make them work, and it needed a decent stall converter. My price for 383 was $5,000 but this was in 2003, so it would be the equal to about $7,500 to $8,500 today. My 6.0 that replaced the 383 after it blew up was 2/10s faster in the quarter, a lot more street able and I didn't have to mess with the carb all the time. Today I don't think you can beat the 6.0 LS, back in 2003 the 383 was the way to go.
Such a great car totally I’m in love with this ❤❤❤❤
I'll take the 383...forget about all that additional wiring...keep it old school
Yeah me too I’m looking for one now
@@toon_on_24s get the blueprint they are the best ones I jus got me one about a year ago runs extra hard
Right.Just change out those heads and the 383 will be in the 500 hp range.
To be a true test their should have been a drag strip test involving slicks. That would have showed the torque advantages on the street. The LS lq4 and 383 small block are both good engines. I’ve owned both but the torque advantage of the small block is way more fun.
Great vid perfect info for which swap to go with 💪🤙
Both of these engines could be built better, cheaper. Both have equal potential, but the LS is a better starting point. I've bought a junkyard 350 for $100 that I built for a truck, and I just bought a junkyard 5.3 for $150 that I'm gonna build for my other truck. The prices are pretty close. If you plan your build out you can achieve alot with the old school. The ls is just slightly more expensive to build but already gives you alot. True motor heads appreciate both and know how to build both. True fanatics are waiting for these LT engines to start showing up in junkyards
I will take either one for free🤣🤣🙌🏾but their both great engines and that ls is jus in another atmosphere 💪🏾💪🏾💪🏾💪🏾
They didn't add in the mounting brackets or serpentine system price of the ls vs 383. You can rebuild a old sbc for cheaper than doing a LS swap. Which of the motors have the most torque at lower rpm's?
If the LS is all aluminum, it's weight savings is like added hp and tq.it takes more eng to move more weight. If both eng make same numbers on dyno the car will go quicker and faster with aluminum eng in it.
I like them both
Just imagine if they dropped a roller cam in that 383 Stroker those numbers would've been totally different 🏁
No they wouldn’t lmao
@@Se7enthsonSS You don't know what I know 🏁
You forgot the cost of accommodation since with the LS you'll be buying a whole new pulley setup and mounts.
Why not substitute a Roller Cam for the difference in price and make its somewhat of an even comparison? Maybe list the cam specs used for each as well ?
huh??? For 7k you can build a 434 with afr heads and roller cam putting out 600ish for that price
Wth costs 3400 bucks to get a complete engine running??!!!! Holy crap.
bucksnort bumblefuk ikr super cheep for a engine
MPG, emissions?
My two favorite engines. Nice video. Keep them coming. More info on the 383 would be awesome. there isnt as much info on them as ls motors
Because Chevy never offered a 383, it's a combination of a 350 rods and pistons with a 400 small block crank
@@alexmosqueda5246 more accurately, the combination of a 350 bore width with a 400 stroke length. You can't use 350 pistons and rods in a 383 build as-is. You can use a bog stock 400 crank though with 400 5.56" rod and standard 350 pistons, but you can't just take the piston/rod combo out of a 350 and use with a 400 crank. Some disassembly and reassembly is required :D.
If you're buying new parts you'd use a longer rod with the pin up higher in the piston, reduces weight of the (shorter) piston. The aftermarket companies give you several rod length options on 383 stroker kits. For example Scat offers 5.7 and 6.0 options on 383 kits.
What are you smoking? The general 1 sbc has been aroind since 1955 and a legend in the racing community for generations the 383 is one of the most popular builds for a sbc has been since the 80's on up and even more so in the late 90's early 00's. What some good 383 write ups? Go to a c4 Corvette forum and search for 383. Information on them is everywhere
@@danegrossnickle2550 ok but u can find shit about ls motors practically EVERYWHERE. not just on one corvette website....
@@JimBronson yeah I wasn't really trying to give an in depth explanation, just explaining why he'd never see official GM 383 references and specifications since they never offered it originally besides from how they sell them as crate engines now after the fact they become popular builds.
Do y'all still have dis engine
Wonder if I can slap either of them into my 98 318ti 🤔🤔🤔
The cheapest solution is to use a remanufactured LM7 ($1500usd) short block and dump as much nitrous as you can afford. One car just dipped into the 6s on a stock bottom end 5.3. If 4340 forged parts with ARP fasteners make you sleep better at night, get a fresh block for $750usd, a 383 stroker kit for around $2000usd, and sent it to the machine shop for assembly ($1000usd for final machining and tolerance checks.) Bullet proof for under $4000 and 600fhp
How does an engine require 3000+ in parts to install? Something isn't right here.
This is mainly an Ad for Speedway motors trying to convince you to get the extras. I think with the LS it will definitely be expensive due to all the extra wiring, computer, etc.
But the 383 should be relatively simple and cheap as long as you don't buy a $2000 carburetor.
Exactly my thoughts as well, but still think 3k is absurd unless you're paying someone to do it.
@@TheBikemaster94 you can rework the stock lq9 harness for free and engine mounts cost like 50 bucks. Cam is 600 with springs and headers are like 500. That's 2300. Ls>sbc
@port nut the engine was complete!! They are saying to get the engine, a complete engine, running they spent a extra 3500 bucks!! Carb,400, dizzy,300.. I have no idea.. could a bought some really nice heads and a cam and a intake... doesn't add up.
Brand new rebuild 383 vs LS with no telling how many miles and wear. And the amount of work to swap is 3X. the numbers on the 383 were low, for no extra cost or labor the 383 can easily make over 400/400. I like both motors but unless you just need to say “it’s a LS” I wouldn’t do the swap. Just my opinion. I could be wrong
Hmmmm. Tiny cam in that 383 vs a .600 lift cam swapped into that LS.
I see LS swaps everywhere and hard to beat their bang for the buck. If your doing a nice muscle car I say go for the pretty under the hood and stay old school.
I like LS engines as much as the next heard, but they're not as "cosmetically fitting" as the gen1 sbc and bbc. That said they're a perfect fit, and look great in g body's and 80s cars like Corvette's and third gen Camaros and firebird's. But I like how a bbc fills the engine bay of the classics too!
A better comparison would be a crate LS motor, not a used one since the 383’s price was listed as a brand new engine.
Isn't A crate LS engine around 7k
manny6584 That’s my point. Then the horsepower per dollar would not be as impressive with the LS.
@@danielj3230 well no because they are comparing what they want to compare. We should already know the price of A new LS
what could one expect gas mileage wise with the 383 using a Sniper TBI or FITECH TBI any of the ones on the market today? as opposed to the set up on the LS you put in...or say any 3600 pound car or truck with 342 to 373 gears with a 26 inch tall tire running 70 to 75 mph and some mixed driving and a overdrive trans.
Jeff G Mileage has many aspects to compute and driving habits plays a big part. Other things is the terrain you drive in, altitude, and weather conditions. The EFI setups would net the best averages and in most cases the LS proves to be more efficient. Driven respectfully mileage could range from 15 to 20 mpg.
@@speedwaymotors So the people leaning toward the LS will take this and run with it...the Stroker Guys will dig in their heels and go the opposite way...LOL But yes thanks for the info I suppose I will hunt down a 5.3 LS then not looking for crazy power this is for my retired aunt and her 64 chevy Short Fleet she liked everything about it...except for the 87/95 350 she called it a dog even after adding the sniper and 373 eaton tru trac gears...Just goes to show you I thought she would be happy with that I should have asked her before hand instead of assuming.
Price has gone waaay up in all their engines. I got my 383 from BP around the time of making this video. Very under rated product and company imo, I bought the same 383 in this video I think. I would buy it again in a heartbeat, it is a monster and has hurt many feeling.
They are both Chevy so win win either way . If you have old school parts built that and have fun.
What are the pulleys for on the 383?
Would a lt1 383 build be able to run on pump gas
Regardless of all the comments below about the needless $ spend, the 383 just looks a heck of a lot better sitting in there. Old school and traditional.
I would bet the 383 gets off the line quicker but eventually the ls with pass it. The 383 might be more fun on the street, more tourqe in the low range of the rpms.
The 383 is missing about $1800 for the parts that should’ve been put in it, $7000 price to run Is for those of us who don’t know better
What was the machine work done? It seems like you did nothing to the short block. Is that correct?
.... That sbc will kill an LS.... Correct cam timing events and an small asca lobe profile with amc lifters would twar an ls up any day
I would rather have that stroker torque curve flat across the board that i will feel every time i touch the pedal than the 5.3 peak hp that you only get a few seconds at a time.
This LS was 6.0L or about 364 CID.
@@jimsvo4486 It's hard to beat a motor on stock cubic making more that a old school sbc 383 stroker from Ls head flow ro less cubic inchs still out Hp the 383 sbc Gen 1 motors
For what these clowns spent you could make well over 500hp lol
Shit, that 383 could have made over 600hp NA with $7500 spent in the right places.
Okay fellow gear heads, I have question. I have access to a brand new zz383 crate engine, well not brand new but never been run or even started up, this engine is about 7 to 8 years old has the fast burn aluminum heads, roller lift cam, high rise intake. According to GM this thing makes 435hp and 450lbs I believe? My friend has this motor sitting in his garage and is willing to sell for $5100 as is. I know that GM has discontinued the zz383 and replaced it with sd383.
Question: Is $5100 a fare price for a 8yr old engine that's never been used or ran, also is the newer version of GM'S offering the same engine spec wise? I'm planing on putting this into a 91'z28 with a 700r4 trans and stock rear-end
I have some old 350 blocks and a 400crank that I may just have built using some type of Vortec cast iron heads. I hope for 425 to 500 hp and over 500lbs torque, something I can use as a daily driver.
With a 3-year/50k mi. Warranty, no less... And the valve springs haven't been sitting for years unmoved... Not to mention the cylinder walls... Surface rust... Just sayin. This would be my preferred drop-in choice + comes nearly ready to run with a dyno sheet. I know a few who purchased these BP 400 motors and they're happy as can be with the performance. Forged Steel crank, alum. heads, roller cam, forged internals, carb... dist... Just a good deal for the $.. and you won't lose a friend if something goes awry with the zz motor... 🙂🤘🏼🙉🙊🙈🤑
@@andyreiwitch8845 Well, I went with zz383.So far we have put it on a engine running stand and fired it up, it starts real quick just needs more carb adjustment. This motor came with the blue beehive valve spring and aluminum roller rockers. I hope all goes well when we install it in my 91 z28 ,we will see!
@@Bossman_71 Fingers crossed, friend!! Long live GEN I SBC!!!
yes the LS may edge out the old small block in performance, but you simply can Never dress up any LS to look as good as an old SBC.
short answer for best value: use the one that's original to the vehicle it's going into.
I got my 383 blueprint from speedway motors but I also like summit they are both just as good
I imagine your fuel mileage went up with the LS. As compared to the 383.
Who cares its a muscle car no buys these cars to compete with priuses
David Deleon Deleon what do you mean you sound sped the amount of people who by muscle cars to modify them to race and some cost 20000 and 50000 right now
@@wickedmachines5136 i have no idea what fuck you just said🤣🤷♂️
My debate right here. I have a 350 in my cutlass that I’m thinking about stroking. But I’ve also thought about swapping to a 6.0 truck LS. Decisions decisions.
You can stroke a 6.0L to 408ci if you're looking to party
350 stroker: Cool, simple, lots of periodic tuning (unless efi), uses a lot of gas.
LS: complex (...relatively), runs and starts more reliably, uses less gas.
2200 bucks will buy you a Edelbrock RPM top end kit. If you got a good 350 it will get you 410hp by just bolting it on. Spending money on the extra stroke doesn’t do much good without a good top end. If it were me I’d build the 350 top end first and enjoy the easy 410HP for awhile. Later you can always stroke it to 383 and you will already have a great top end to take advantage of the extra cubes 👍🏼
Buy a 5.3 with computer and harness for $500 add a Brian tooley racing cam package $500 cut the harness yourself send computer off to have it tuned $300 buy engine mounts and spacer for flywheel $200 boom $1500 running driving cammed ls with 400 HP plus 20 miles to the gallon take ur 350 buy a complete stroker kit $1000 machine labor $300 if u assemble yourself now you needs heads and a cam to match 😂 buy the 410 HP kit $2000 now you've got 450 HP 8 miles to the gallon keep in mind the 5.3 for $1500 take it port the factory heads $500 at Wilkes performance plus $100 for shipping add stroker kit no machine work assemble yourself boom 500hp 15 miles to the gallon
My ~500 hp 383 has EFI and gets 18 mpg highway with a 6,200 lbs Express van wrapped around it. Way less to build as well.
You didn't say how much torque did 6.0 liter make.
What about the torque?
My sbc 396 stroker from blue print puts out 505 hp 520 ft tq and motor was 5999.with 50k warranty
Ive been thinking about buying this engine, how are you liking it so far? trying to figure if there if its the right route vs 383 and 400 small block. thanks for any info you got
GOOD 383 but to get to $7250.00 that is quite a jump.i built my 388 cheaper.
An those numbers are wrong on a stock bottom end pistons rod heads cam Ls. I wish these shows just be honest it would help more people like them more. Couse if you a real grudge racer or car guy you know when something is off.
About to put a new engine in my Chevelle I'm going 383 long block reusing my intake with dual four barrels and using my chrome power steering pump and polished ac compressor .and pullies ..was thinking about going LS but I'm hurting for time and having to change so much stuff including gastank which is already new right now the old school engine is best ft or my situation
Good luck with your build!
$3000+ in parts to get the sbc running? Y'all smokin some gooooood stuff.... ironic it just happened to come into price comparison of the LS which in your video "needed conversion brackets". But we all know the sbc bolts right in.... Yesh, this is like comparing a Chevy to a lambo then marking the Chevy up so the lambo looks like a steal lol
Your LS setup ran $7700... But if the you already had a. Sbc In The vehicle then yiu can swap all your current stuff over leaving you a cost of $4k +/- necessities.
But you could also find a higher hp LS at pick'n pull for $400 (with the ecu, etc.), then add some cheap mods of the same price.
But I agree, if you just want power and minimal effort, modify the small block.
Youd have to waste a shit ton of money for an LS transplant for it to cost $7000.
And a 5.3 with a BTR 212/218 @.050" lift cam will make 430 crank hp.
Throw in a Comp
54-454-11 cam and valvesprings and it will make 460hp or more with stock unported heads. With ported heads it will be at 500hp.
It's all been dyno proven.
And IMO, wasting $6-800 on a intake for 6- 20hp is ignorant.
Especially when the NNBS or TBSS intakes can be had for under $150 and will out power the LS1,LS6, and all those Chinese sheet metal ones.
@@O3h529 It doesnt take $7000 to build a 383 either, FFS could easily build a 406/427/434 if doing the work yourself. They also have a 383/396 packages dressed with EFI for under $6800 the 396 makes 485 hp 500ftlbs. I have already pointed out a Vortecpro 467BBC Intake/Pan Flywheel/Flexplate make 620hp 590tq for about a thousand less than the LS here. Of course it needs carb and headers but still making way more power. Pretty simple if the engines can flow the same amount of air their performance will be similar, cost comes down to location and end user ability to build it.
American auto industry as a whole kind of lost it but yet still you can play with great iron in your garage! Expensive Lego constructors for boys from 16 y.o. and older.
The dyno proved that intake killed the 383.
@UCHHaEFxYTPFWdQbL45DHZog
I would like to see the same test with similar flowing heads , cam and both running a ls1 ecu . That would of been a fair comparison. How and why did you spend so much on a gen 1 sbc. I built a fully forged 383 turbocharged heads cam intake. w/ ls efi and coil over plug system for 6500$ every nut bolt from oil pan to throttle body was new.
I'd like to see the marine version 383.
It's mild
454 long block $1850 & 450 core. Seems like better deal
Yeah but that’s not factoring in installation time if you’re doing and extra cost if you have someone do it. I went 383 route for my 85 Camaro IROC-Z
If you cannot get 500 horsepower out of a 383 you need to go put your tools up and start playing golf. I can get that out of a 350 all day long without $800 headers and all the other crap y'all spent money on that you didn't need should have put that your motor
GreenBoy at GA Farms 😂😂😂
@@ronaldwilliams4053 👍
It cost about $4000 to do so the ls they had can make 500 HP with a cam only for about $500 and done
Greenboy 500 hp on pump gas in a 350? I've never seen one yet. It might be possible but I ain't seen it and I've been drag racing and building engines for 25 years
@@jrod264winmag really you need to do another activity, with the right heads ,cam pistons, angles, and if you port,better yet even more , I been building street strip motors for 30 years ,and I found if you use junk,not the right, or less then optimal parts you get crap. And the only reason the ls did so much better is the ports ,the way they are designed and flow. They do make the same types of head for the older blocks ,they are few and far between. Now I have a 350 standard bore, a questionable lift, aluminum headed. Runs on pump gas 575 hp to the flywheel. Cost me 5200dollars, but everything is matched with everything.
7 grand for that much power from a 383 is ridiculous, you can legit get a full 383 rotating assembly from summit for 1K CAD, give me 3 grand and I bet I could make that and even more on both of those
You got the ls out the junk yard added a cam and intake you made no upgrade to the 383 where did the 4 grand go it probably cost anther 2 grand to install the ls so now your at 9 with it
ONE IS BRAND NEW FOR 7K ! THE OTHER IS FROM THE JUNKYARD WITH WHO KNOWS HOW MANY MILES ON IT FOR 7K! ILL TAKE THE NEW GEN 1 THANK YOU!
Bith are way overpriced...
I will still take the old school SBC!
So you spent 3500 dollars on just a few parts to make the 383 run?? WTF!!! It shouldn’t even be close to 7,000 bucks total lol. It sounds to me like the scales got tipped against the sbc to favor the 7k LS.
Its shouldn't even cost 7k for the ls.
looks to me like there wasnt much of a shootout here at all. starts with $3500 383 stroker and buys valve covers then puts it against a $1200 junkyard motor and both total out to the same price?
i have something similar torque wise to that 383 stroker for under $1000 including rebuild on a small block and have full fuel injection and theres no way id swap it for an ls motor.
their only good for flat out high rpms they dont have the road manners that a small block has thanks to torque on the bottom end low rpm range.
put a trailer behind a stock one and they get crippled. mines liable to snatch the trailer right out from under the load.
The difference between these two HP is always gonna be the power direct injection provides
So put a big aftermarket cam in the ls and it makes more HP than a small cam SBC. Not a fair comparison
I'm gonna get the 383 stroker with 536 hp and 483 tq for $6,100 for my 1983 GMC Jimmy. Just need some headers and I'll be on the road
For the price and u can get a little more power outta of it with Minor bolt on's,, or u can supercharger it for real Getty up the LS might be the way to go.. unless u r going for the old-school look then u have no choice 383
With a cam upgrade on the 383 and maybe a few other things 525hp or better and the cam and the few odds an ends wouldn't break the bank.. and my opinion the 383 is brand new and the caddy engine has many miles on it '2004' and u don't know how the 1st owner took care of it but that's why u have a choice,,and that's why I like both engine's an a good excuse to by another car lol can't have a good motor just sitting give it a girl friend and dog it full send at every light,, corner,, mustang,, etc etc lol
Lies. First off in my honest opinion, Blueprint uses a very mild cam in most of their builds. Whoever the parts supplier is is a little pricey. Here’s the deal, let’s take 10k each to a junk yard and let’s revisit this scenario. I guarantee the small block will come out on top every time.
Who needs power steering on the dyno??? I'd love to see a more comparable matchup, perhaps a solid or roller cam with EFI on the small-block
Better stock cylinder heads and a larger diameter camshaft ain't got nothing to do with making good power . It's them coilpak things ....they make the more power
383 sounds mean!!!!
Wow
You forgot to mention fuel mileage of them both
pound for pound the 383 was blueprinted, which says reworked from scratch. the LQ9 was a junkyard haul. if you truly compare the LS would cost you more to start from scratch.
I build the 408 LS out of a lq 4 it was out of a 99 suburban I never had a Dyno tested but I chassis dynoed my suburban it made 361 ft pounds of torque at 3600 RPMs and that's all the information that I have because my old phone got screwed up I was wondering if anybody could translate that to crankshaft horsepower and torque it's a 2001 Chevy suburban 3/4 ton four-wheel drive with a 4l80e transmission
So what your saying is just get a supercharged toyota 5.7 motor .I think..oh wait. That's what I say! I mean 600+ to the tires, gobs of torque , pump gas and toyota reliability and if you get good with the toyota 6spd you can blip the throttle and downshift and it sounds just like heel toe.! Or you can put it in drive and let it do its thing. It's built for a truck so heavy abuse in a car should be fine maybe a long combo but full-size car might squeeze it in there.
Sorry for the effort and we are all hating. I think most of us feel you left alot of sbc on the table.
I would love to see a complete running weight comparison..not bare blocks on a bathroom scale. everthing you need. SBC vs LS real weight comparison.
If that 383 would have had a decent flowing head on it this would have turned out a bit different. 8 grand isn't a "budget" build,
Even if they were equal price. One is new and one is unknown condition junk yard engine. That should be taken into account. Not apple's to apple's.
I feel this to be an unfair comparison due to the fact that you did not start with a junkyard block for the 383
For 7 grand total in a sbc he should be pushing 600+ easy. This was obviously a biased comparison
Gm never built a 383, so it's usually cheaper to buy a built 383 then to go through the labor of building one.
@@danegrossnickle2550 A 383 typically refers to a GM 350 block with a GM 400 crank stuffed in it to get the extra 33ci through a longer stroke. Chrysler did make a 383, but that's not the engine the blueprint 383s are based upon. But I agree. If you want a 383 go get a used 350 block and a 400 crank and start from there unless you have thousands you just want to spend.
@@tubehound69 you have to machine the block of the 350 to clear the added stroke, and depending on the rods used you'll have to turn the rod journals down to run a 350 rod. Anywho, it's still cheaper to buy a blueprint 383 than it is to buy a 400 crank and labor to machine plus rest of build. But anywho, we all do things differently. I'd rather have a scrramer 377 vs a 383. 377 is a destroked 400. Everyone wants a stroker, but a destroked motor will out rev a stroked motor...it's peak power is usually found much higher on the rpm band then a stroker.
@@tonyblackburn5002 100% agree. Smart man
15 degree heads now put 15 degree head on that sbc
They dont want that comparison 😎..
That would kill the LS ALL DAY LONG... the dont wanna see a 900horse sb2.2 setup in a 383...
Tell me why u can build one of these for 1/4 of what they say u can on both ways lol
Could have built a lb9 ported on a roller 383 and made the same its all about the dry intake
And we all already know 383 is an 8000 rpm engine if done correctly
