Facts

[@dtruth5769]

That's short stroke revs so quick. Love them 383 & 400's

[@JustMoparJoe]

And hidden torque! How many times have you heard that they can’t make torque without revving? This one has over 500 foot pounds from 3,800-4,900

[@aaronbarnes8938]

Very impressive numbers for an engine that didn't even make 200 horsepower from the factory.

[@gavinmclaren9416]

I reckon it's all in the compression. The 400's of the mid-seventies would have looked enviously at the compression of a Briggs & Stratton.

[@JustMoparJoe]

Thanks Aaron. This was a 2 barrel beater at one point

[@johnfitcheard7112]

DAMN good power and torque ! Very similar numbers to that 440 max wedge on Nick's Garage

[@JustMoparJoe]

She’s a runner! So much fun to drive on the street with all that power.

[@JustMoparJoe]

Thanks brother. Should have a good 60’ with the right converter

[@drmopar6122]

The street dominator intakes pick up quite a bit if you weld up the spread bore pattern to a square bore type pattern. But they’re such a good piece that the Mopar Performance B intake is just an improved version of it. Holley put a LOT of R&D time into the street dominator intakes.

[@JustMoparJoe]

Check out part 3. Definitely worth the watch.

Truly the 340 of the big block wedge family. I think the TR is as good as it’s going to get this side of a modified Edelbrock STR-15 or a sheet metal intake. There’s probably more on the table with a pair of 650-700CFM 4150 carburetors. But that’s a very happy combination, great job!

Go for it! They have great potential. This is my first, but definitely not last

[@SteveP-vm1uc]

Same here. I wanted to build a 400 simply because it's a lot of cubes in a short package. Far easier to hide a monster without a scoop!! The thing is, back then, even the engine shops were tossing 400's and 383's for the 440's and Hami's. Hell, I junked a Charger and a Cordoba with running 400's in them!! (Don't be crazy, I lived in Western NY and there was zero left of the bodies)!! I sent a Demon to the crusher too! Only thing worth keeping when I got it was the steering column and rim blow wheel and the buckets... The rest was trashed by salt and the pick up that didn't stop in time...

[@JustMoparJoe]

You hit me in the Chevy distributor 🥸

[@gavinmclaren9416]

Awesome! Especially the flat torque curve with the tunnel ram. I think if you went with the TR in your Barracuda you would want to give a lot of thought to converter selection & rear gearing to take advantage of it. I asked in my long winded reply to your comment on the stroker build video how much idle vacuum the 400 is making & I'm still curious. If you recall kindly let us know. I don't think it would differ much with any of the intake manifolds.

[@JustMoparJoe]

Thanks Gavin. I will check it out with a gauge whenever I get it in the car. We never fooled with the vacuum levels at idle, because all the tests were at wide open throttle. I would bet it has good vacuum at idle with the cam specs.

[@gavinmclaren9416]

@@JustMoparJoe Thanks, Joe. I will remind you when you post up a video with the engine in the car. As I mentioned, vacuum will be a critical parameter as I plan this build.

[@gregtough9055]

Great video!!! I am quite surprised how that tunnel ram squashed the performer RPM on torque, I would have thought otherwise. Great job on the engine build.

[@SweatyFatGuy]

longer runners make more torque below 5000.

[@gregtough9055]

@@SweatyFatGuy I get it and it's well known, but typically a straight shot tunnel loses a wee bit of torque

[@SweatyFatGuy]

@@gregtough9055 it depends on how big the port is in relation to the cid of the engine, the opening events of the camshaft, and how much velocity it can make. With a Pontiac increasing the size of the ports increases torque everywhere in the rpm range in engines 389ci and larger. Its so pronounced that one of my engines, a 467 pump gas build with a solid 270/279@.050 110LSA cam was making over 650ftlbs at 3000rpm and carrying it to 5500. Put that cam in almost any other engine, especially one with short runners like small blocks and B/RB wedges and its not going to come anywhere near making that much torque anywhere in the RPM range. The old cross rams made Pontiac like torque on the B/RB engines, they have very long runners. There is a lot going on with airflow through ports and intake manifolds.

Tunnel ram porting video was excellent, good approach to port work, I’m sure there was some nice gains there , those old school long runners always did well with the toque curve, keeping your gearing and convertor in the sweet spot will be the ticket.

[@Musclebuildinglabs]

Great numbers but I bet those valve springs aren’t very good. The power drops off way too fast at upper rpm With that Cam and solid lifters it should rev better and peak around 6200 and carry to 65/6800 no problem. I would call PAC and get a good set of springs

[@JustMoparJoe]

I’m not saying it’s not possible, but it’s not probable. I tossed the edelbrock springs and Ed installed some new crane springs. 165# @1.86" and 400# @.540" so easy on parts.

Thanks Dizzee! You’ll be one of the first people to see the engine run in the car! As for the intake, you can use the 383/400 intake on a 440 with the adapters, but the 440 intake is too wide for a 383 or a 400. Hope that helps.

[@kingnothing8286]

I have a 72 Charger ..New 400... I used an Edelbrock RPM intake #7186 and an Edelbrock Carb # 1407... I have heads from 383/400/440 and they all work on a 400....... Just installed Lokar kickdown.......best idea yet

[@mohanperformance.enginerd.1308]

Is my bet

[@andrewelliot5516]

awesome - again, tunnel rams should not work according "experts" - that just killed the RPM all the !way up - can't wait to get my 400 done!

Thanks Andrew

I can’t believe he though it was going to LOSE torque….

Joe what was the first dyno run

[@JustMoparJoe]

It was my last video up. Definitely worth a watch. I didn’t want an hour and a half long dyno video, so I broke it up by manifold choice.

Thanks brother

Bigger cam!

[@JustMoparJoe]

I thought about that. This cam makes good numbers without overrevving anything, on 91/93 pump gas. That’s a good bracket engine

[@dtruth5769]

@@JustMoparJoe That's true. But there's a lot left on the table. That thing would make max hp closer to 6500.

@@dtruth5769 I have a line on a tame solid roller and new springs. But I won’t change the combination until I can try it at the tracK

Awesome build tunnel ram Rules Looks like someone with years of Experience did all the quality machine work and inspecting all the parts This wasn’t your 3 spring loaded honing stone or ball honed Build

[@JustMoparJoe]

Absolutely true! Thanks brother

[@williamturner8422]

You should NOT loose torque !

[@williamturner8422]

Hey Joe, your 400 block, with Trick Flow heads and a turned down (to 400 size mains)crank can make over 600 horse power. If you check out AR engineering ( Andy Finkbiener) there is a lot of information on big block mopars.

[@JustMoparJoe]

I have no doubt. The goal of this was to see what it would do with the stock stroke. I could probably write a short book on the discoveries of this engine and how it’s such an underrated platform.

[@williamturner8422]

@@JustMoparJoe there is a reason that B-1 heads are almost always used on a 400 block.

[@DragCadRacing]

I'm sorry, I'm about 2 minutes into this video and I'm not liking what the dyno operator is saying and predicting what will happen with the tunnel ram. I understand that there's a common myth that tunnel rams are for high RPM, but that is a myth. (Just look at the first graph.) But someone who supposedly knows engines enough to be a dyno operator should know better. Longer runners tend to produce higher low to mid-range torque. They can also sometimes push up the RPM peak for horsepower.

[@DragCadRacing]

However, Joe I suspect that you already knew that before he opened his mouth. 😆

[@JustMoparJoe]

Thanks brother. I agree,my life of seeing tunnel rams on the racetrack says the same. Aaron was helpful with the dyno and is very familiar with it. But he’s not familiar with big block mopars. The other myth is that the short stroke of the 383/400 can’t produce the torque that a 440 can. I think we are crushing that one too! Hope you check out parts 3 and 4. I promise it all gets better!

[@pokebass1]

I have a hard time trusting a man who thinks that a tunnel ram will make less torque than a Performer RPM. It's as if he doesn't know a thing about high performance intake manifolds.

[@tetedemarc]

I'm not surprised lolll !! I did try similar set in 2000ish . Those Weiand Tunnel works Perfect !!!! When I pull the heads the chambers , piston top were perfect color all over . There was no dark or lighter spot. kzbin.info/www/bejne/emXFm56meLaig5o
