The Mighty Hemi.
Still kicking butt after all these years!
Well this is billet so kinda different.
I'll take one of each, please.
Super delivery 🙌🏼 top marks for sharing this real world perspective 🍺
Awesome! It's amazing what you guys have accomplished!!! A long way from our days working on cars in mountain park.
Here to see what may potentially be going into Cleets new custom chassis racecar as he moves on from mullet
thanks for the breakdown boys. excellent video!
Both blocks are absolutely beautiful. Flawlessly machined.
WOW!! What a great video. You in include street out laws, RVW, and NHRA. Lots of information.!
A lot has changed since this video came out. 2 years ago the go to for the Street Outlaw guys was the 481-x but now it seems a lot have switched Prichard Hemi.
Great video, have been curious about this same topic for a long time.
The welding on the ribs in the lifter valley is perfect. I've never seen that on an engine block. Looks like Tig bead, but its flawless.
So cool. Please keep doing these type of videos
I was happy with my recent 9.89 @139 a few weeks ago, then I watched this video.
Still be happy. Its a start shit my car is still stock with the a.c. ripped off lol
9:89 sounds like you're kicking ass to me.
@@jiveturkey9993 Its alright. But these engines on display here, are definitely next level. Were talking knee deep into 4 digit power. Would love to experience a full tilt hit, with something powered by one of these.
Cool decision making insights, thanks for sharing
I ain't even a mechanic but I love watching these videos lol
I just got home from PRI I wish I could post pictures of how bad ass the proline procharged AJPE hemi stuff is!! Red had mafia changes the game REGULARLY 💪🏼😎
What alloy aluminum are they made from and roughly how many CNC machine hours does it take to whittle one of these finished blocks from a billet?
What bore spacings and bores sizes can the 481x accommodate safely with fire ring grooves ?
What’s your thoughts about 481-X in tractor pulling with 14-71. Boost, tq, rpm?
I will never be able to afford one those, so why am I Watching this?
@Dave Franklin so you have a spare 50 large laying around?
@Dave Franklin sorry but I am in the telecommunications industry and I don't go hungry nor do I brag about it troll.
@@garymckee8857 You need to ask yourself why your watching this rather than blurting out somebody is a troll. Watching something but saying you can't afford that is passive aggressive. There is far too much of that going on in Western Culture. If you want to buy a ProLine engine you can. The question is will you make the investment back if you do so. If you believe you will, there is more ways than just plunking down $50,000 cash (not including turbos/supercharger, ignition system, fuel system and engine control system. Nevermind dyno testing, chassis dyno testing and track testing. Not willing to commit? Stay in the wading pool.
Why so serious? I think things got lost in translation right out of the gate. I took it as a joke and that's it. Didn't try to read into it at all. It's just a comment on UA-cam for Pete's sake. 🤣
Felt but it’s good to stay updated on what ppl are running, when I talk racing weather it’s street, strip, pro, funny. It’s good to know and to learn
These engines are insane. 😳
The LS’s nice but real deal is the Hemi all day tried and proven add proline in and done deal. Amazing machines guys keep killin the game.
The ax man cometh and kicked everyone’s ass a few years back with their hemi and procharger. Fast forward to 2022….
Yeah he did!
Could either of these be used for freeway pulls?
ok eric said this why this motor got designed. Did u folks design with AJPE or just proline great vid congrates on ur sucsess at proline happy and safe holidays
Can you do a video on the water jacketted version
Like Big Chief said about the Hemi powered Vixen.. "He can do 200 in the eighth mile while I can only do 186...But I can do 186 real quick"...
joe cucch - Big Chief isn’t running a 481X. He is running a real Pontiac 455. But I suppose the comparison is similar.
@Dan Myers; Yes he is running a wedge head like the 481 X so the similarity is there.
Vixen split a collector in that race and was down almost half it's boost. Chief can't sniff Vixen with both on a clean pass, either in ET, or MPH.
@ geneticrex; Losers always have a reason...
LOL.....That came from the crew chief of another competitor I happen to know.. NOT VIXEN.
You may not like the reason, but it IS the reason. Vixen is a 5 second 1/4 mile car. Any car in competition can win a race, but in a clean run, with both cars leaving on time, as good as his car runs, Chief has nothing for the top cars in no prep.
Can this engine fit right on my honda civic?
Will a f3x 140 procharger work with a 481x
I would like to see a video of the Noonan Hemi vs the Brad Anderson Hemi what is the difference and why is one better than the other????
Thanks Good Video
awesome video for us non motor guys
So much for Street Outlaws going with 481X over the HEMI. 😂
ARE YOU GUYS IN BALLGROUND, GA ?
Laughed when you talked about most of the street outlaws guys running the 481X over the hemi. Obviously this video is a year old. One year later and lots of the SO guys are switching over to the hemi with a Procharger. List includes Daddy Dave, Ryan Martin, Axeman. Even JJ DaBoss is running the combo in a car he purchased from Axeman.
BTW, less torque is a big advantage in a No Prep car. Makes the car way more tunable.
@@danmyers9372 most of them did it for weight in npk.
@@Brandon_093 - Yep, another big advantage for sure.
@@danmyers9372 The Hemi has less low end torque than the 481X but since most On Street Outlaws that use the Hemi are either Procharged or some kind of supercharger that brings the low end torque back. The 481X is mostly seen with turbos on Street Outlaws and since it has better low end torque it helps make up where the turbos are lacking which is on the low end.
Is the 481 a small block
what I'd like to know is this; "how close is the rotating assembly to that of a top fuel motor??"
when you say "3 or 4 numbers "do you mean tenths or hundredths?
MOPAR GUYS always love THE HEMI, since it is THE KING...and the most beloved engine in the world.
It’s not even a dodge thing they’re just talking about the heads of the engine many many engines use hemi heads you dodge guys are brain dead
@@CoyoteFTW it is most certainly a Chrysler thing, it's a Chrysler design, brain dead, they even say that lol
@@The_Turbo_Charged - hemi is NOT a Chrysler design fanboy
@@CoyoteFTW ..No, but Chrysler had the Hemi in the 1940's in their Airplane engines(prototype) war ended so they shut the program for future plane engine..They designed a car engine and used the Hemi heads and in 1951 the Chrysler Hemi car engine was born and it ruled the drag strip since!
Other companies had hemispherical heads even some 4 cyl engines .Chrysler registered and made the HEMI name synonymous with them.
NHRA today everyone uses a Chrysler HEMI based on the 1960's Mopar Big Block 426 HEMI...Chrysler even had a Wedge 426!! Today Ford,GM,Toyota in Drag Racing all use the Chrysler HEMI,yes built by aftermarket companies but you cant say its a Chevy or Ford or Toyota engine,its a Chrysler HEMI...I know that troubles a lot of people,quickest Chevrolet,Fords,Toyota's are basically Chrysler Powered!
How does the 481x compare to the SMX ?
481x with f3r-136 procharger for no prep or no?
what ever happened to the big inch v6
When they window the blocks like you see on tv are they repairable?
20 years ago when a nitro powered car “ windowpanes a block it was actually still good enough for an alcohol car to reuse after some welding. Nowadays when the bottom end lets go CSI couldn’t find half the pieces of the block never mind any parts that used to be inside the engine.1400-1500 HP per cylinder when it miss fires doesn’t leave behind a whole lot reusable parts.
RVW they already ran 3.55 in qualifying and side by side and 3.58 "s in the finals ...
But more related to the video what kind of combos are doing it constantly?
think id go for the hemi what do you mean by the hemi using 2 time more parts, I would only do a 100 runs on a set of aluminium rods so are you saying to change out Rods at 50 runs does it matter if it was twin Turbos to a pro charger, I have noticed that guys are about even for the pro charger and Twin Turbos
Hey Doug I remember the days you did that
Big boy toys puts me in my place makes me realize I haven't grown up yet
One question nobody ever asked for answers is what does 481 actually mean what are the nominal bore sizes for these for 81 as compared to the Hemi and what kind of heads are the best on a 481 how many cc's are they blah blah blah
Pure art!!! Anyone want to sponsor a retired USAF aviator with a blown alcohol nostalgia funny car? 🤣🤘🤘
So y don’t y’all combine the two engines and Mack one bad block
So when he says wedge in the 481x, is he talking about the piston shape? If so what if you used the wedge with the hemi to maximize compression?
Wedge combustion chamber. Not piston.
Pro line is hands down the best. I’ve wore 2 snap back hats out. Need to get new ones. Lol
I think Noonan and a lot of his customers would argue that point.
Is a proline hemi a true mopar hemi engine ??
CNC artwork!!!
make a shirt with a picture of one of those beautiful blocks and i will buy it
Great video
so why does NHRA limit racers to the HEMI?
Because its the best...Ford tried back in nthe early 2000's with their own Ford engine but it cost them too much money and it broke all the time so NHRA made a rule making everyone run a HEMI...and these are based off the Chrysler 1960's Hemi.
I thought the 481x had hemi heads on it also
I’ll take one of each to go please...
Is this black friday where you buy one get one free.
Is it just me or does the main narrator look like he could be Jeff Lutz son
Doug reminds me of Tim McAmis a bit
What percentage of Nitromethane can be run using the 481?
Good question, I would imagine 98meth and 2nitro
99% depending on your tune and bank account
Ryan Martin just switched from the 481X to the Hemi and so is many others so I'm not sure why but will see if it runs better then the 481X that's all I can say
He switched for weight reasons. The 481x with 98s had to weigh 3100lbs. Pro charged hemis are 2750. That’s for npk. He’s doing good now as are the rest of the pro charged hemi guys but there’s more than likely gonna be weight added to them next year so we will see what happens then
Very, very cool
It’s crazy watching this now and most of the street outlaws are running hemis now
We can't afford it but we're motor Freaks and we can dig it.
I have a lsx376 and i run 4.40s so it just depends on you budget mine was 10k
Bullshit.
4.40s…….for $10k? Lol nah son
@@LilCarterOnDaMic pretty sure that's 10k for engine
Lmao. Um ok.
Lsx376ci that runs 4.40 for 10k…..maybe for the heads….. lol….
481X’s on the street... F yeah! 😎🤘
SemI hemi chevy...you see mark woodruff bright yellow vette on the fuletach dyno? Man thats just stupid but $$$$$$
mrhazel, Yeah that car is unreal. 👍🏻
Dont care what ANYBODY SAYS NOTHING BEATS A HEMI
i always am amused when i see serious fiberglass bodied "chevy" cars at a drag race event and always the most serious ones have full tilt race engines based on hemi architecture.
as long as it's not dodge making it!!! good thing these guys are around to make the design reliable. I've seen several vids of guys with NO2 and a pulley swap on their hellcats start pushing to or past the 1000 hp mark, and boom. they usually loose to a built coyote or LS too before the hemi goes pop lmao
people should check out the southeastern gassers and their rules its alot easier to build a car for that series if a person wants to drag race
Looks like the 481x has a lot of similarities on the front end 🤔
Question; aren't the basics of the block the same so the heads are the biggest difference right? So where is the real difference in the short blocks?
wish I had..$$...but are they talking just talking 1/8th mile passes?..I think the Hemi is well suited for 1/4...over the 481x...
Gota love a hemi!👍
if I ever win the lotto I won't tell anyone but there will be signs lol these motors semi with blower and 481x turbo in my holden street cars would be wild
Great video...from Wyoming USA 🔫🤠

Thought hemi was just the heads so confused on why im looking at blocks someone school me on this I'm new to motors but was taught hemisphyical delt with the heads only
Cant wait to see how cleatus McFarlands engines going to do!
In the Hemi what’s up with the groves in the cylinders?
Valve relief
Are you sure it’s not for a ringed head gasket?
I think he was referring to that not the reliefs.
Andrew Hill Top fuel hoops! A must in blown engines. Yea baby!
Andrew Hill Oh, I think I know what he’s talking about. Those slots just below the top of the cylinder sleeves.. Around the 9 minute mark. I have no idea what those are!
Ok, because it looks set up for o-ringed head gaskets too
I'LL TAKE ONE OF EACH . PLEASE
How many cubic inches can a 481x be poked out to?
572ci is the most common
@@keefespencer1173 theoretically I think it could go up to 632, I wasn't sure what the deck height and bore space was
It depends on the deck height. If it’s anything over 10.3 it could be 650+ci’s
@@18wheelzofsteel53 10.3 litres is from 626 to 632 cubes.
@@markdubois4882 depending on stroke bore. I should clarify. On an aftermarket 460 block which has the same deck height as a factory 460 block of 10.3 you can build 658 ci's. That's if you got 4.7 bore and 4.75 stroke crank.
The 481x block has a 10.4 in deck height and a 4.84 bore.
If you plug the numbers alone with just a 4.75 crank that will put you at 700ci.
When that Hemi walks around you in high gear, you will switch to a Hemi....Top Fuel & F/C use Hemi's for a reason ..!
they have to use a Hemi in NHRA
No they don't...The rules just say 500 ci engine, 14-71 SC, and 87% nitro ...!
Hemi makes more power. That’s nothing new. The ability to apply that power and the spread of power is why people chose the 481x. It’s less expensive and can make 90-95% of the same power.
lol
I agree 100%....The hemi head allows you to make more cylinder pressure, and you are firing the mixture from the center of the hole...it's just a better design for an internal combustion engine...Thanks to Tom Hoover ! I've built and worked on Top Fuel Hemi's ...Too bad they have to be so expensive..!
Music was a little too loud
best of the best
The really crazy thing for all you Lotto dollar winner who buy ProLine motors maybe some of you can remember back when a guy named Spiro Pappas ran his steel body steel cowl 69 Camaro with his 430 inch Big block from Fast Times with one Turbo to a 6.72 218 MPH 1/4 mile rolling on a 10.5 tire and did that round after round with Billet nothing and 1/10 the budget .. So while all that Bling is real pretty .. it's really just Bling for guys with more cash than ability ..sorry but I've seen this so many times before ...
I grew up old school. I remember the tech that was around in the 60s and moving forward. Back then 400 to 600hp was fairly easy to obtain but 800-1000hp was not . When 1000hp started showing it was big dollars and it still is. It’s the old saying “ hp dosent come cheap and if you want to play you have to pay. I’m a big of old school engines, old school tech but the simple fact is that the tech that’s out there now for making big HP absolutely burys old school across the board and on top of it ,it’s reliable kinda of sorta. For example, look at the power and reliability that’s out there now, dodge,ford, GM are all offering engines capable of making 700- 800hp easily and they are offering 3 year warranties. I agree with what your saying , I understand the argument and as hard as it is to admit it, new tech ain’t no different than old tech when it comes to dollars, you get what you pay for and the stuff that is out there absolutely puts old school tech to sleep. I’m just sayin…
@Rick Johnson 1000 hp is nothing these days and certainly doesn't take big bucks to achieve. I'm also old school to the point that as 12 year old, I got to work with Dick Landy in his pit fetching tools back when those cars were running times that are considered slow by today's standards. No one could've imagined that we'd have cars with air conditioning running sub 10 second 1/4 mile times.
when i look i see mostly Hemis in the street outlaws all the top 10 have Hemis
What about fords.?
If the 481x is so good for NPK, why are the top Dawgs running the Hemi?
probably wouldn't run a china cast piston in those huh?
YES, TRUE TO EVERYTHING YOU GUYS SAID..... EXEPT ONE MORE THING
THE HEMI STAYS TOGETHER AND WILL TAKE MORE PUNISHMENT
Didn't you guys make the new Murder Nova a procharged 481
These engines can be used in street legal cars?
No
Yes , Larry Larson,murder nova,and a lot of other guys run proline motors
For the practical nature of drag week sure.

What engine is the 481x based on?
Subieroo305 - BBC
@@danmyers9372 BBC with Chrysler wedge heads on it almost similar to the BBC SEMI HEMI which is a BBC with either a 5.0 or 5.300in bore space with Hemi heads on it the main difference is if you look at the front of the block where the timing chain normally is you can see that the Hemi and the 481-X runs pretty much the same distributor location in the front timing cover on a 45 degree angle where as a stock BBC runs a distributor in the back same as the SBC at a straight up angle on the top of the back of the cam and most of your Fords run the distributor in the front of the cam at a straight up angle unless you run VVT and just have the distributor housing sitting up front and a camshaft lock out to plug the factory hole in the intake and if I'm not mistaken you can run coil on plug that way too but you don't have to
Not really based on any single OEM block or head design. It just employs a lot of ideas that work. It has a deeply skirted block like a Chrysler Hemi. The cam location in the block appears to be higher than most wedge head engines. The heads look like the Warren Johnson era Oldsmobile prostock units that were based on the TFS big block Ford. When you see these in Camaro it seems the owner wants to try to pass it off as a BBC but the fact is that the intake ports are not Siamese is a dead give away that it is not a BBC. In the end i would say the block is Chrysler hemi inspired and the heads were Olds/Ford inspired. No BBC though.
@@toddjohnson7133 That pretty much sums it up!
Not any one particular brand of engine. Looks like they pulled different pieces of engine manufacturers designs and incorporated them into one engine.
Just know it's not based on a BBC.
