My Dad had a 1968 Dodge Charger with Factory 426 Hemi,Twin Carter AFB 4 Barrel Carburetors, a 3:23 highway posi rear end, a 727 Tourqueflight Automatic Transmission. STRAIGHT ELEPHANT. The car weighed in at 4025 lbs as he ordered it. His philosophy was extra weight was needed for the Top End. He used to say: " Let the Chevys and Fords HAVE The Hole Shot, we'll come ROARIN' BACK! I was 11 in 1968 and he taught me how to calibrate the Air/Fuel mixture on those Carter AFB's...... I've never heard a sweeter harmony ESPECIALLY when youre rollin' along on the highway and you gradually add throttle....and that second carb chimes in right about 73 mph. Now THAT is a HUMMER!

[@sirswerve2493]

For the ones that dont know. This engine design started in 1964 . It is the only piston engine design ever to run a sub 4 second run in the 1320. It has been and always will be the king of the 1320. Long live live the Chrysler Hemi.

[@Grizzly406]

The 426 is a damn GEM! What a sound!

[@djackthatsright348]

Coming from a drag-racing family, I've seen some pretty awesome displays of pure beast performance, motor-wise. A 454 rat motor is probably my favorite Chevy power-plant, it's brutal, and a lot of performance for the buck ~ small block Chevy motors is one of my all time favorites, and that is the 327 with the extra mains. By chance I had an opportunity to get my hands on a FOMOCO all aluminum 427 motor that was hands down the most ferocious Ford motor I had the opportunity to run/own. But the Elephant is hands down the nastiest power-plant there is. I was amazed at just the rumbling of the vehicle, and the ground vibrating/shaking due to it. Other than the gas consumption, my really only other complaint about the 426 Hemi is you've GOT to be a somewhat knowledgeable mechanic, it requires constant meddling, tinkering with to keep it setup. So with that being said, my favorite BB is hands-down the 440 B block motor, this thing is virtually bullet proof, I've never seen a motor take so much abuse, and still keep right on motoring. Anywhos, that's my 2 cents on the matter, and yeah it's my opinion, and you know what they say about opinions, lmao! Peace.

[@nickpanaritis4122]

djack that's right. Yes the, the RB "raised Block" 440 is a great engine to abuse. And 2nd, I like to hear everyone's opinion, which is great. Thanks for watching.

[@sirswerve2493]

When It comes to V8's this one is a masterpiece . A engine designed for racing then sold to the public. It has held so many records in motorsports. Even to this day the design still powers the N.H.R.A Topfuel and Funnycar class. Long live the Chrysler 2nd Gen HEMI!

MODIFIED (over-bored and higher than stock compression) with no power robbing mufflers, factory air cleaner assembly/element, alternator, etc. in place. Also, modern pistons, rings and other parts (as was the case here) are more efficient than the OEM stuff from 50 years ago.

[@guyforlogos]

I love that you built this all stock! Valve job, point distributor, iron manifolds, belt drive and all, it's great to see how the factory masked the ratings by under-revving the engine for the 'official' horsepower! Sure it's 'only' 425hp at 5000rpm... Wink wink... I can almost hear the salesman back in the days, whispering, 'you should see what it does at 6000 ;) '

[@phoenixrising4073]

It is so cool that you kept the motor stock to appreciate what all those designers worked so hard for years ago. I also like that you share the experience with your friend, that is what life is all about. Great video.

[@charliedee9276]

So cool to see an original HEMI on the dyno. I was a junior designer on the original Viper project and got a chance to work with Willem Weertman, one of the original engineers and co-author of the SAE paper in 1966 detailing the street HEMI. He was a very soft spoken extremely intelligent man, one of the highlights of my design career was having him teach me about this great powerplant. He gave me a copy of the SAE paper titled "Chrysler Corporation's New Hemi Head High Performance Engines" dated April 11, 1966. I have hung onto it for all these years and if you read this Nick I would like to send a copy to you if you don't already have one.

Awesome vintage Dodge engine making vintage Dodge power ..but man how the times have changed, when a guy can buy a modern 6.2 L supercharged Dodge engine that makes 840 ponies, and a naturally asperated 5.0 Coyote engine that makes 500hp on E85. We're living in amazing times my friends.

[@ToyKingWonder]

This is why I love this channel. All when I was growing up, we knew it was underrated, and the general consensus amongst my merry band of gear heads was that this was a 500hp engine, more with some mods. And here we are. Basically stock motor and right at almost 500hp. The beautiful thing is that this power plant can put out these kinds of numbers over and over again without worry to the block, heads and internals. Although not quite the mystique and bragging rights of the Hemi, it does remind me a lot of the big 440 I have in my 1971 Super Bee. You can wail on the thing all day and it never overheats or complains, and then ease up on it and drive it like a commuter car and it doesn't mind gently rumbling through your neighborhood. This is why Mopars are such fun cars!

[@tammyforbes2101]

Yes please save as many old mopars as you can they are my favorites and deserve to stay on this earth for long as possible! I hope some day when future civilizations dig us up the first thing they find is 1970 hemi Charger! I honestly can’t think of any other car that is so loved by everyone! Even non car people are like, ha it’s the General Lee, or that’s dom’s charger and their eyes light up!

[@GTX1123]

There is nothing that compares to the sound of a revved Hemi. In 1982 I worked at a repair shop where the head mechanic had a 64 Valiant Coupe with a 426 Hemi. He regularly raced 1/4 mile at the track on weekends. As a Chevy guy, I was mesmerized by that Hemi. For that era, I think Chevy, Ford and Mopar all had great big block's, but whereas Chevy owned small blocks, Mopar owned big blocks. I always loved it when they fired up that beast up and revved up that Hemi.

[@roryvonbrutt7302]

[@thomasdean3400]

You must have had the solid lifters. The way it was made in '68. The dual points never worked when the dealer set them with a dwell meter. I had to set them with a feeler guage or the engine would break up under power. Frank Distaso in LA did a great job getting the most out of it on his dyno.

Regarding how much horsepower the 426hemi produced, the following statement was attributed to Cotton Owens, NASCAR driver and mechanic. Someone was prodding Cotton and asked him if the engine truly made 425 horsepower. His answer "Yes, at about 3000 RPM." Nick, nice build. Enjoy.

[@redphantom70]

My first car was a 1970 Dodge Challenger N code. Back in 1978 when I was 16. My friend and I would go to the Chrysler wrecking yard in North Hollywood CA. They were selling Hemi's for $300 a piece on crates. I just watched your video and it made me think about that time. To think how much they've gone up in value. He had at least 20 re builder Hemi's. My most recent Challenger on my channel is a 440 with a dyno of 468 HP. You sir know how to build a motor.

[@BobbyTucker]

Nick, That's the same way I do my head gaskets, spray on the copper coat. Nothing better to seal them with.

In 1969 I was an 18 y/o kid and US Marine lusting for a 426 Hemi car. I even bought a 392 (old school of course), Hemi engine from a junkyard later on, thinking I was going to put if into a 70 Challenger that I bought, only to find out that it was nearly impossible for me to do, and a ton of money and work for anyone else to do. Here I am at 70y/o still dreaming and lusting. But, I did get my hands on a modern SRT 392 Challenger. I’ve also had 3 5.7 Hemi cars. I loved every second of owning that SRT 392 Challenger though. It was the fastest true street car I’ve ever owned. I made a few mods(sensible) but it was mostly stock. ultimately all of the mania and thievery around these cars forced me to trade it for a truck, Hemi of course. I love my Hemi Big Horn but I do miss the difference in performance and the aura of my former car. Maybe, if I live long enough, and the social climate changes, I’ll get me a Hellcat or even another SRT 392. At my age and health though, I’m not really interested in becoming a target for carjackers or thieves. Still, I love me a Hemi, old or new. Keep the faith. “Mopar or no Car”!!

[@unclemikeb]

The dual point distributor is not to be frowned upon. I had a 69 road runner with dual points and it could turn 6000 rpm. I learned to shift at about 5500 just to be on the safe side. Dual points allow more flexibility. They can be set with feeler gauge but they are best set up on a Sun machine. My Road Runner felt like it had 30 more horsepower after a guy put mine on a sun machine and reset the ignition timing. If I was quick with the shift and popped the clutch it would lay down 5-10 feet of rubber when I hit third gear. But Nicks hemi is so awesome it makes me drool.

I owned a 70 challenger but only had a 318 in it. I had to sell it for cheap to move from Indiana to Arizona. I sure loved that car but when you got family you have to make sacrifices. I sure made a sacrifice with that one. I wanted to put a hemi in it but once again the money reared its ugly head and I couldn't do it, was in the Navy back then and only made $344 a month. I was blessed to have what I had with that kind of chump change. Anyway its very cool to see that motor roar like that and know your putting it into my car not (MY) car but you know what I'm saying. You are a real mechanic and very impressive. Sure would like to own one of your cars. Blessings to you Nick. I knew that engine made more then they said. You built this one for longevity not racing.

Congratulations Nick! Now put the heat tubes back on and run it with a hot manifold. Include some stock mufflers and an air cleaner and lets see the numbers.

[@anoint426hemi6]

Nick, Back around 1968 several of the car magazines rated street 426s more like 500 hp.. There might have even been a dyno feature. As a (nearly 50 years)long time Hemi owner, I wouldn't be surprised if the numbers are higher with better ignition and attention to carb tune. I crank my '68 Hemi Plymouth to 7,000 with no problems. When I drag raced it 40 years ago it saw 8,700 rpm a few times..driver error and never came apart. Still running the stock connecting rods and crank it was born with! I didn't see it anywhere, you might mention Street Hemis had the puniest camshaft stock at around .470 lift versus Chevys that some were nearly .600 lift.

My Street Hemi ran 11.30@124mph with a solid lifter .595/607 mopar parts camshaft, carb jetting, headers, 5.33 gears which from what I recall factoring in the weight of the car, the motor was making 630-650 hp. That might have been what it was with the .700 lift roller.. oops.

@Marty McFly your preaching to the wrong person. Preach to utubers who seem surprised

Truly amazing Nick. I had goose bumps watching. Keep making history please. Dave

About 15 years ago one of the Mopar magazines did this exact same test and came up with almost identical results. The only difference was that theirs wasn't bored .30 over and had stock CR. They got 475 hp and 475 lb-ft. The best thing about this test is that it's a video - totally better experience actually seeing and hearing the tests!

- Yes ! One more time before we all die.. Good times. Waited a real long time for someone to do this. Thank you sir.

[@Stratsrule]

Always loved the carb setup on these engines

[@jameshardin1100]

The rumor has been confirmed. 425hp at 5000 RPM, But near 500hp at 6000 RPM. Great Work!

Dr. Nick, I have watched this video so many times that I have lost count, it is a classic, cheers.

I don’t think it’s possible to like two people more than Nick and Manny without meeting them than I do you could just tell how cool they are!!

And THAT is why Everyone Else was looking in the back window of the Mopar Engineers Garage Shop to see "What's Next?" Well Done Thanks Nick MOPAR Rules
