My upull had a 2008 Denali today and I scooped a L92 complete from oil pan to intake water pump and accessories for $250!!!!!!!!!!!!!!!! My dream came true today
Before I got into more serious grudge racing I would juggle out stock 4.8/5.3 bottom ends without even knowing what engine it was. Throw one in, throw the FITech on it, boost it, race it, hurt it, swap in a new one. Now I’ve had an engine in the car almost 2 years and it feels weird. Lol
Usually the lower stroke engine is a bit more stable at RPM which is what boost likes, i have a 4.8 on my truck and a 6.2 in my Camaro. I have actually considered swapping the two out so i could boost the 4.8 as it would not only be cheaper but the 6.2 piston lands cannot handle the power the smaller 4.8s do, the truck would also benefit from the beefier lower end of the bigger engine for loads.
@@johncrankshaft2886 The stroke has little to do with high RPM stability. Weight of the rotating assembly and internal balance of the rotating assembly would make a much bigger difference than stroke or R/S ratio. That matters VERY little. Valvetrain construction/components are the most critical though. Honestly the way the oiling system and pan is setup is more critical to high RPM stability than stroke as well. I’ve seen some very tall stroke engines rock out 8-9-10k RPM all day long and laugh it off. But then I see engines with an imbalanced rotating assembly, or old extremely heavy cast internals with a so called “optimal” stroke/RS ratio not be able to make anything or safely spin up above ~5500.
@@johncrankshaft2886 you should honestly do it no Mustang or scat is gonna even come close to a boosted 4.8 Camaro, coyotes and 392 struggle to make power way before the 4.8 even sees its peak on stock block
After watching this and many of your other videos on LS performance, you really can’t make a bad choice! I word go with the 5.3 for the higher average power numbers. But like happened to you, if you pick up what you believe to be a 5.3, but it’s really a 4.8, no reason to complain, just rev it higher!
I love the 4.8 its the underdog, under appreciated. Lol having said that I have a 5.3 in my project and 4.8 sitting on the shop floor . Maybe one day I'll throw it in and boost it to the moon . Just to see what it does.
I love my 4.8…….when I bought it the seller was under the impression that it was a 5.3, he had it in a jeep cj5 and would humiliate brand new ford raptors in multiples of 4 or more…..he would just stand on it and after about 5 seconds or so you’d see this lil red jeep emerge from a clusterfuck of $100k fords…..I seen the videos and I was sold….I personally helped him pull the motor out of the jeep…. Weeks later when I went to install it in my nova upon changing the oil pan I noticed the casting numbers on the crank and to my surprise it was just a 4.8…….I wasn’t even mad though, it had a 220/220 cam and hardened pushrods and accommodating springs….it would rev to 7500 easily……that’s why I’m putting a vortech centrifugal supercharger on it and calling it a day!!! I’m shooting for around 600hp give or take
I have loved nearly every one of these videos, keep up the great work. Like many my focus up to this point has been turbo high effort street cars. My next project is a primarily off road Jeep, so low torque is the name of the game. I would be interested in a video looking at some NA combinations that focus on this as a goal. I am sure there is something in your archive that is applicable. Thanks again Richard for the masters class in engine combinations.
You’re a beast brother. Every time someone says something stupid on the go fast ls groups, someone always pops in with “ go watch Richard holdner” . Anyways brother, I’m sure your rich already, but I do hope your properly capitalizing on your fame and success. You deserve it! And thank for all the helpful research.
Nice! I am starting my first LS engine swap project and I am learning a lot of the differences between the different generations and sizes. Was super surprised to see half ton gmc pickups that came with no afm even in 2009! I actually found an all aluminum 6.0 called the L76 out of a 2008 half ton that said vortec max on the doors. Building that engine now for my e46 bmw.
@@crisitanc5666 not hard at all with tons of 5.3 rebuild videos out there. Don’t mess with replacing main bearings and rod bearings. Use stock rods/pistons from a gen 4 engine preferably. Try to install new cam bearings at the very least with a new cam retention plate and oil pump pickup O-ring as these are the number 1 premature failure points on stock bottom end 5.3s. Throw some Chinese head studs with LS9 headgaskets and .26 and .28 thousandths ring gap on the top and bottom piston rings if you’re gonna be pushing more than 16 pounds regularly. Bottom line, keep it simple and cost effective.
@@timweb1510 Gap your stock rings, replace the oil pump pickup tube o-ring, and replace the cam retainer plate at a minimum.Valve springs are a must, so get some PAC 1218 springs. You can rock the stock pushrods if you want. Some cheap speedmaster head studs if you're gonna be pushing more than 15 pounds all the time. And some snake eater performance 100 or 150 lb injectors with either a single walbro 450 for less than 700 hp, or twin 450s for more.
It really all comes down to budget but all I can say is the 4.8 is impressive and with boost can't go wrong really I believe if you can drive it on the street hell even daily it you made a successful machine
I'd like to see how high you can actually rev an LS before something goes wrong. Either all stock or with a lightened valvetrain. Maybe titanium pushrods rockers retainers with dual springs.

Hello Richard. Ok. I’m standing very corrected and that feeling that my brain 🧠 was misfiring badly. You kinda argued that a 5.3 cannot get to 500hp without modifying the heads. I mentioned it too with someone else who said it was possible. So far you haven’t showed us that it’s possible with stock heads and stock intake. I know you recorded a video with a 5.3 getting close to 450 with a cam only swap. I know I seen it. Maybe again I’m convinced my memory is correct. Keep revving up those numbers. Lol great info Richard .
I have never made 500 hp on a stock 5.3l short block with stock heads (maybe with 799 heads, a big cam and flat top pistons and short runner or carb intake
You can take the block and punch it out to 99 mm. Use the 5.3 crank and you have yourself a “350”. Really more like a 346ish but that is a poor mans ls1 lol

Plucked my 4.8 off offer up as a stripped long block with God knows how many miles and what kind of bearing conditions. But its destiny is that of a huge nitrous shot first, then add an ebay turbo kit. Project Shitbox is underway!
Moral of the story. A 4.8 will still make a butt puckering street machine and you'll be left with figuring out the trans and rear end just the same. I think that if one thought they were getting a 5.3 for a classic car street rod weekend warrior LS swap and ended up with a 4.8 they would still be pretty stinking happy with it's performance. And if they blow it up then most of the parts and investment will translate well to a 5.3 or a 6.0.
Hi Richard! Great videos you are making! Are you rymning 1100hp on a stock gen3 LM7 bottom end with just ring gap for turbo? I am a Swedish Guy building a timeattack Volvo 142 -72 with a Corvette C5 drivetrain and a LM7 at first. Aiming for 1000hp at the wheels. Do you think i should go stock bottom end or do forged Pistons and conrods for durability? Thanks a bunch! 👍
I hate LS swaps, simply because EVERYBODY does them. That being said, they’re great engines and I’ve almost convinced a very anti-LS buddy into swapping one into a 74 Firebird project. His only caveat is that it’s a 6.0...I’m pretty certain you’ve run stock 5.3 and 6.0’s with carb intakes...so I’ll go on the search! I remember a magazine article years ago that took an LQ9(pretty sure) and did a piece by piece build and the thing made 415hp with just a carb & dyno headers, then like 495hp just by adding a cam and springs to it. I can’t remember what magazine it was but it sure would be nice to find it again...my magazine “archive room” is mostly full of MM&FF and 5.0&SF. Lol
Too bad we don't see either of those over here in Australia so finding a dirt cheap LS is like finding Rocking Horse Poo! To my knowledge we only got the 5.7 6.0 & 6.2 litre LS varints. As they say bigger is better! 🤔
How about doing a plug-and-play? To have somebody around my location tune a twin turbo on a LS motor your talking big bucks.and a long wait time . how much power can you get with off the shelf parts? I like the 5.3. Because I have one .😅😅 thanks for the video Richard.
I just bought a 5.3 LM7 I believe it’s out of a 2000 Yukon I believe with 862 heads. I am going to put it in my 4 door 65 nova that has church boys racing suspension I want to drive the family around but still hit up the drag strip and a road course along with some auto crosses, I would like around 750-850 hp at the wheels I know that’s a bit much for auto cross and road racing but I still want it lol what would you recommend as far as a budget engine build it will be ran with Holley Terminator X.
@@infamousnova generally, you want to pull a degree or two at peak torque with a blend in/out about 400rpm either side. Then, at about 800rpm above peak torque feed in another 1 to 2 degrees to carry the torque out farther. On e65 I feed in another 4 deg above torque peak on a 4.8. So 14* at 3000, pull 2* at peak torque (4700rpm) and finish at 18* at 6600rpm. This is on 20lbs of boost with twin GT35s...in a 4000lb street car. Made a hair over 780whp.
I'm building my first street car ..with a 2004 mustang and I was wondering what would be the better build for power ..the 4.8 or the 5.3 really not a turbo guy just running on motor muscle 💪
I have a 94 hardbody and looking for a swap. I didn't want a V8 but it looks like they're cheaper to build... What do you think 4.8 or 5.3? I think bcs of the weight I should go with 4.8 due to torque but I'm not expert so I hope to get a experts help
@@richardholdener1727 but do you think having a 5.3 In a small 94 hardbody will make it spin too much with the torque being at lower rpms...? Since the 4.8 the peak horse power and torque is up much higher in the revs
Thank you Richard! I have read that a 4.8/5.3 block is identical and it is only the crank and rods pistons that make the difference! I found a good block that has 4.8 internals in it. I should then be able to put my 5.3 internals into it and have a 5.3 is this Correct? This is what I read online. I am new to all this. Any help would be greatly appreciated. Bradley
I wanna run a stroker engine in my truck, should I just take my gen4 5.3 to get bored and worked over with the stroker kit or do I have to run a 6.0 block? Looking for over 400 cubes
Richard, this one might take a second or 2 to spit out.....so here goes nothing (sorry if your brain hurts already, just seeing a question from me again). In regards to Gen3 LS. Since the L33 5.3L uses the same piston as the 4.8L LR4, but the same Rod length and stroke as an LM4 5.3L Gen3, would it fair to assume that since the LS1 uses the same Rods/Crankshaft as all 5.3L Gen3 motors, that the LS1 Pistons and 4.8L pistons are the same Pin Height ? Would throwing a set of LS1 Pistons on 4.8L Rods and prepping the block to accept them, be an easy way to get a bit more out of a 4.8L by adding what is essentially 20 cubic inches overall ? (293 to roughly 313 with aftermarket 3.905 Pistons). If you have a 2005-2007 4.8L LR4 with the Gen4 Rod and floating pin update, would this upgrade make sense if you needed to get pistons and do block prep anyways ? Also, in those Gen4 rods, would upgraded ARP fasteners make any sense ? or are the OEM designed fasteners the best for those cracked forged rods ?
What if you ran the exhaust straight into the intake, properly sized of course, you would have a zero loss system once the rpms achieved balanced rosonance.
I got a question, I’m building an LS 4runner. To mainly run in the dunes. So it’ll see a lot of RPMs, and load from paddle tires. I’m only shooting for around 450-500hp on pump gas. I can add higher octane or even run 100-110 VP. Should I tear the 5.3 apart to gap the rings. Or run it as is? Motor is a gen 3 LM7. Stock everything, 706 heads with a small turbo.
I have a 4.8 and I wanna get a 5.3 and boost it but I’m not sure if I wanna just boost my 4.8 or get a 5.3 😂 probably 4.8 bc I beat the everliving piss out of my motor and it runs basically as smooth as a brand new motor
But those are two totally different engine combinations you can't even compare apples to apples is more like Apple's vs. Oranges. If we're going to do an engine comparison use the same head use the same camshaft of course you use the same truck intake manifold which is great but they're not the same.

Both 4.8 and 5.3 have same bore, but different stroke is what makes the liter size higher
Correct. And with the shorter stroke put less leverage on the piston as it is forced down the bore and causing less piston rock.

Moral of the story. A 4.8 will still make a butt puckering street machine and you'll be left with figuring out the trans and rear end just the same.
I think that if one thought they were getting a 5.3 for a classic car street rod weekend warrior LS swap and ended up with a 4.8 they would still be pretty stinking happy with it's performance. And if they blow it up then most of the parts and investment will translate well to a 5.3 or a 6.0.
Hi Richard! Great videos you are making!
Are you rymning 1100hp on a stock gen3 LM7 bottom end with just ring gap for turbo?
I am a Swedish Guy building a timeattack Volvo 142 -72 with a Corvette C5 drivetrain and a LM7 at first. Aiming for 1000hp at the wheels.
Do you think i should go stock bottom end or do forged Pistons and conrods for durability?
Thanks a bunch! 👍
Okay let’s say I want a 4.8 build with a 10 speed automatic twin turbo what’s the best reliable transmission to go with?
I hate LS swaps, simply because EVERYBODY does them. That being said, they’re great engines and I’ve almost convinced a very anti-LS buddy into swapping one into a 74 Firebird project. His only caveat is that it’s a 6.0...I’m pretty certain you’ve run stock 5.3 and 6.0’s with carb intakes...so I’ll go on the search! I remember a magazine article years ago that took an LQ9(pretty sure) and did a piece by piece build and the thing made 415hp with just a carb & dyno headers, then like 495hp just by adding a cam and springs to it. I can’t remember what magazine it was but it sure would be nice to find it again...my magazine “archive room” is mostly full of MM&FF and 5.0&SF. Lol
a cammed 6.0l can easily make 500 hp
@@richardholdener1727 i need to make a believer from a skeptic! Lol
How about an LT converted to port injection? Some folks don't like the direct injection and the kit to convert it is not expensive.
Too bad we don't see either of those over here in Australia so finding a dirt cheap LS is like finding Rocking Horse Poo! To my knowledge we only got the 5.7 6.0 & 6.2 litre LS varints. As they say bigger is better! 🤔
I would like to see you run a Cadillac supercharger with dual turbo`S WITH A STAGE 2 CAM
I like the idea of a turbocharged 4.8 but my bigger is better side always wins. Time to boost my ls1.
How about doing a plug-and-play? To have somebody around my location tune a twin turbo on a LS motor your talking big bucks.and a long wait time . how much power can you get with off the shelf parts? I like the 5.3. Because I have one .😅😅 thanks for the video Richard.
off the shelf parts?
Most power with add on parts with a power programmer? With out going to the dyno.idk.🤔
How much boost you running..
Richard: "ALL OF IT"
The rave music is always good
The best combo period is a 6.0 block with a 4.8 crank long rods . Absolutely tyre smoken fun . A little bit like the old small journal 327 .
Honestly 4.8, cause now wondering if it will fit in a Pontiac Fiero?🤔
IT DOES
How about a old school 305 vs.350 SBc....twin shoot out or a big bang 350 ,?
Love your concept. But why can't we see the dyno runs?
OLDER TESTS HAD NO VIDEO
I just bought a 5.3 LM7 I believe it’s out of a 2000 Yukon I believe with 862 heads. I am going to put it in my 4 door 65 nova that has church boys racing suspension I want to drive the family around but still hit up the drag strip and a road course along with some auto crosses, I would like around 750-850 hp at the wheels I know that’s a bit much for auto cross and road racing but I still want it lol what would you recommend as far as a budget engine build it will be ran with Holley Terminator X.
cam, springs, boost
I need low end torque and a motor I don’t have to rev out to get going. Especially on a four speed automatic...5.3/5.7.
What was the timing advance at max boost 19lbs for the 5.3?
19-20 degrees on race gas
@@richardholdener1727 Are you pulling timing at diff kpa/psi or are you running the timing set all the way?
@@infamousnova generally, you want to pull a degree or two at peak torque with a blend in/out about 400rpm either side. Then, at about 800rpm above peak torque feed in another 1 to 2 degrees to carry the torque out farther.
On e65 I feed in another 4 deg above torque peak on a 4.8. So 14* at 3000, pull 2* at peak torque (4700rpm) and finish at 18* at 6600rpm. This is on 20lbs of boost with twin GT35s...in a 4000lb street car. Made a hair over 780whp.
@@littleherms3285 ok thanks, now I just have to find peak tq lol
Right on
No mention on the injectors you're using in these "junkyard motors"?
INJECTORS NEED TO MATCH THE POWER LEVEL-120 POUNDERS AT LEAST
I'm building my first street car ..with a 2004 mustang and I was wondering what would be the better build for power ..the 4.8 or the 5.3 really not a turbo guy just running on motor muscle 💪
5.3
@@richardholdener1727 ok ill do some videos on my progress and feel free to send me some pointers
You are the ultimate engine channel lol.
I have a 94 hardbody and looking for a swap. I didn't want a V8 but it looks like they're cheaper to build... What do you think 4.8 or 5.3? I think bcs of the weight I should go with 4.8 due to torque but I'm not expert so I hope to get a experts help
the 4.8 and 5.3l weight the same
@@richardholdener1727 but do you think having a 5.3 In a small 94 hardbody will make it spin too much with the torque being at lower rpms...? Since the 4.8 the peak horse power and torque is up much higher in the revs
Thank you Richard! I have read that a 4.8/5.3 block is identical and it is only the crank and rods pistons that make the difference! I found a good block that has 4.8 internals in it. I should then be able to put my 5.3 internals into it and have a 5.3 is this Correct?
This is what I read online. I am new to all this.
Any help would be greatly appreciated.
Bradley
yes-the 5.3L components will both right into the 4.8l block
Oh Heck; Rich got dance moves? Wow? Not bad either. Double R; (Rocking Richard) n the house.
Question Rocky, in the light car with gear acelaration reving speed of 4.8, higher rpm shift point would give better ET, also easier to hook up ??🏁🚩
This question is highly confusing, you sure you know what you are asking?
Are these junkyard engines tested with the stock injectors also?
stock injectors won't support these power levels-they require much more fuel
Great upload
Tbh.. I'd use either.. depends on what i have
5.3L Richard. Of course Gen IV rods. Displacement rules. Maybe babying will give better gas mileage to the 4.8L.
I think the 4.8 spins up in rpm quicker but u loose out on low end torque its really hard to saywhats best except top end the5.3 will win out
I wanna run a stroker engine in my truck, should I just take my gen4 5.3 to get bored and worked over with the stroker kit or do I have to run a 6.0 block? Looking for over 400 cubes
if you want over 400-then a 6.0 block
@@richardholdener1727 thank appreciate It buddy. Now to find an affordable gen4 block
Richard, this one might take a second or 2 to spit out.....so here goes nothing (sorry if your brain hurts already, just seeing a question from me again).
In regards to Gen3 LS. Since the L33 5.3L uses the same piston as the 4.8L LR4, but the same Rod length and stroke as an LM4 5.3L Gen3, would it fair to assume that since the LS1 uses the same Rods/Crankshaft as all 5.3L Gen3 motors, that the LS1 Pistons and 4.8L pistons are the same Pin Height ? Would throwing a set of LS1 Pistons on 4.8L Rods and prepping the block to accept them, be an easy way to get a bit more out of a 4.8L by adding what is essentially 20 cubic inches overall ? (293 to roughly 313 with aftermarket 3.905 Pistons). If you have a 2005-2007 4.8L LR4 with the Gen4 Rod and floating pin update, would this upgrade make sense if you needed to get pistons and do block prep anyways ? Also, in those Gen4 rods, would upgraded ARP fasteners make any sense ? or are the OEM designed fasteners the best for those cracked forged rods ?
THIS IS DONE A LOT-THE PIN HEIGHT IS THE SAME, YOU CAN UPGRADE TO GEN 4 ROTATING ASSEMBLY-ARP ROD BOLTS NOT NEEDED
What if you ran the exhaust straight into the intake, properly sized of course, you would have a zero loss system once the rpms achieved balanced rosonance.
EXHAUST INTO THE INTAKE?
Be interested to see how much power all acc's cost..basically in full street trim that 80% run
the ACCs video is up
@@richardholdener1727 thank ya sir!!
@@richardholdener1727 Hmmm.. don't see.it Richard
My boost combos will start with a 6.0 of course.
Bingo
5.3 is 0.1 liter bigger than a 318.
I rest my case.
#440 😝
Now where's that $ button in this chat for the 5.9 Magnum testing?!?
😂
What's your thoughts on stock ring gap on a 180k+ bottom end?
GOOD LUCK
parts list for the 4.8l please? I can't find anything.
THE PARTS WERE COVERED IN THE VIDEO
whens the how to get max power from a 5.3 coming out??
see big bang 5.3l video
Whats the specs on these turbos?
I got a question, I’m building an LS 4runner. To mainly run in the dunes. So it’ll see a lot of RPMs, and load from paddle tires. I’m only shooting for around 450-500hp on pump gas. I can add higher octane or even run 100-110 VP. Should I tear the 5.3 apart to gap the rings. Or run it as is? Motor is a gen 3 LM7. Stock everything, 706 heads with a small turbo.
What about junkyart turbos?
Or diesel ones
those work
Rich
There's always a small dip in the curve at the start
Is that the Dyno load in ?
On the road power doesn't behave that way
just the dyno release
I have a 4.8 and I wanna get a 5.3 and boost it but I’m not sure if I wanna just boost my 4.8 or get a 5.3 😂 probably 4.8 bc I beat the everliving piss out of my motor and it runs basically as smooth as a brand new motor
either works
About how much power can you expect to get on stock injectors
depends which injectors and what fuel you use
I wish i had your talent im fixin to build a 5.3 as a factory mud bog 2003 tahoe i need s cam help a brother out ill pay shipping
Can't wait til you get your hands on the v6s from nissan and hyundai some day
Would be awesome!
Is there a dimension diff between 4.8 and 5.3?
same external size (different stroke and rod length)
Is the LS7 the same external dimensions too (to 4.8, 5.3, 6.0, and 6.2)?
@@richardholdener1727 thank you sir
But those are two totally different engine combinations you can't even compare apples to apples is more like Apple's vs. Oranges. If we're going to do an engine comparison use the same head use the same camshaft of course you use the same truck intake manifold which is great but they're not the same.
they are the same if you understand ls motors-the displacement is the biggest variable
What is the cost of the modified LS?
depends
What music do you use?
13b big bang
I'll take the high revving 4.8L please!
Personally I blame squirrels
Biggerer is more betterer
More ford stuff.
