Well this is billet so kinda different.

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.

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.

Yeah he did!

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.

@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 KZfaq 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

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.

But more related to the video what kind of combos are doing it constantly?

Doug reminds me of Tim McAmis a bit

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. 👍🏻

I think Noonan and a lot of his customers would argue that point.

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!

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.

Bullshit.

4.40s…….for $10k? Lol nah son

@@LilCarterOnDaMic pretty sure that's 10k for engine

Lmao. Um ok.

@@billallen4793 Where do you want me to lander🤣🤣

@@dakotaautosales9673 probably your shop, it's convenient...lol

@@billallen4793 Man already did that lol

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.

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

Good question, I would imagine 98meth and 2nitro

99% depending on your tune and bank account

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..!

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

This message has been brought to you by the Ford fan boy club. So ask yourself if the John Kaase Boss motors are so great. When was the last time one of his great motors won an NHRA Pro Stock event? Or better yet has it EVER won one. NHRA chased the latest version of the Hemi out of Pro Stock by limiting the amount of RPMs the engines could run to just 10,500 and by the way that HEMI motor was turning the highest RPMs in the class, won back to back championships before NHRA decided to slow the cars down with EFI and no hood scoops. The cars have never run as quick or fast since then.

@@CoyoteFTW What year was it that ford made a 426 boss? The next thing is that you ford guy’s can’t seem to understand is that pro stock motors back then (nitro followed right behind the ruling) had to comply with the stock part of the rules. The S.O.H.C. was never installed in ANY CAR from the factory it was an experimental crate motor that ford was trying to pass off as a stock motor, the only thing that motor came stock in was a shipping box and I don’t recall seeing any lined up with the real cars at the dealerships. When Bob Glidden was winning with the 351 motor NHRA had put so many restrictions on the Hemi that they made it unusable, if it was used in a Cuda, Duster, Challenger or any other similar sized cars they had to weigh as much as the truck that towed them to the track, if they tried to make the motors with smaller CID then they had to use smaller valves??? They made it so you could not use the motor in pro stock. But Bob Glidden saw the potential of the 340 Mopar and at the first race with his New Plymouth Arrow he set both ends of the pro stock records with ease, so much for your mighty Cleveland motor. I don’t know where you got the idea that Warren Johnson “made” big Cleveland heads and put them on his Oldsmobile motor. At that point in time NHRA was still sticking to the factory engine designs that’s why him and Bob Glidden were constantly bringing each other to NHRA tech for excess creativity with their welding work and trying to pass it off as “stock”. The DRCE engine did not come into existence until after NHRA greatly relaxed the engine rules, by that time the factory only had to put a part number on the block or the heads and you were good to go. Chevy or GM had as much to do with the DRCE engine design as they did with the design of the Boss 302 Mustang or the AAR Cuda’s. GM knew that there big block Chevy was never going to be able to complete in the new 500 CID rules so all they did was pay WJ a BOATLOAD of $$$ for HIS design work and put a part numbers on it and the DRCE engine was born. The new Hemi engines that Allen Johnson won with in pro stock were nothing like the 426’s from the 60’s and 70’s and I’m sure the “Boss” engines that Bob Glidden was using was a completely different animal than the Boss 429 from 1969. Technology has called for engines NOT to have 10 pound pistons trying to run the near 12,000 RPM’s that engine builder Roy Johnson was making for his son Allen to win back to back NHRA championships with their team cars. Times and tech has helped all brands to be better.

@@CoyoteFTW I have no idea what this triple crown is that you’re talking about.

@@frankjohnson6342 - the rule was simple 6.75lb per cubic inch small blocks and 7.25lb for big blocks. Means Chrysler didn’t have a small block worth a damn. Because Glidden was getting weight added all the time and he kept winning it want just in NHRA either First 3 years of IHRA pro-stock Cleveland’s won 1974 Wayne Gapp, 1975 Don Nicholson and 1976 Bob Glidden. All without factory support from Ford. That’s why they changed to the 500 cubic inch limit with a weight of 2,350 pounds. Trying to stop the Fords too bad the 385 series Big Block Ford we’re just as good as the Cleveland’s. First IHRA 7 second run was Dyno Don’s gas carbureted 500ci Cobra Jet, it was the first doorslammer of any kind to run in the sevens. Rickie Smith Boss 429 also ran 7.9 first national event. Ford kept winning big block or small block. At least Ford used the Boss 429 Chevy made up an engine “DRCE.” Called it “BBC” That’s the only way they could keep up with the shotgun hemi Ford because they didn’t beat it neither did any Chrysler. Rickie smith dominated in IHRA with a BBF and Glidden in NHRA. Only thing that out an end to the complete domination was politics, funding & crooks at NHRA. To prove it to you so you know I’m not being a fanboy. Tim Lynch’s proline 620ci Ford went 6.53 at 231 mph in a 3,050-pound Outlaw 10.5 car in 2008 a record then. Let's put this in perspective: NHRA Pro Stock cars, typically considered the fastest stock-bodied door-slammers, tip the scales 700 pounds lighter at 2,350 (with driver) and use a considerably wider tire than Lynch's 10.5 did. The record in 2008 NHRA prostock was 6.53.. with the crappy DRCE. Tim Lynch’s Big Block Ford would hold the record in NHRA all while weighing 700lbs more and way smaller tire..

@@CoyoteFTW glidden at 2350 lbs with the ok from nhra used nitrous same with the dodge boys that is the only way they could compete look at glidden crash at alanta and watch what he does when he gets out of car. ford and chrysler production engines suck

Valve relief

Are you sure it’s not for a ringed head gasket? I think he was referring to that not the reliefs.

@@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.

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.
