How reliable has the engine been? Valvetrain, Block, lowend, etc.? Stock block or aftermarket?

Just curious honestly. Might experiment with it sometime way in the future.

You would make more power with a W8 headed motor.

I know, I was curious because I want to use it for a future Super Stock GT combo so I wanted to know if anyone else had messed with a combo like this.

Many a high-winding SS 383 has been built over the years. No reason to think it would be different with a few more cubes. Piston selection has always been the issue with the B-crank motors. But if we're talking ab out a super-stock motor, typically we're talking about a "money is no object" type of build, so I would think you coould easily find a way to build sufficient compression.

Joe Alread ran a 1972 Plymouth RR 4 speed wit the 400 engine in SS in the early 1970, ran so good Mopar hired him as one of theire factory racers after that

Dave Wren ran a unbored 400 block in his 1971 Barracuda 383 SS/I car also with the proper carb and head part numbers, it whup a lot of GM cars in that class

Dave and Greg Smith ran the same combination(1971 383) in thier 1971 Cuda in SS/IA also. it was a rocket ship

With todays technoogy and SS class rules pick the year (lowest factory rating with a four barrel, truck or car

) of the engine you want to use and go for it

I have a shortblock sitting here in the shop that I should probably sell since I don't have a need for it. It is a stock stroke 400 with Manley rods and JE domes. It ran really hard with a set of Dwayne ported Edelbrock heads.

Bob Mazzolini is currently running a short stroke small cube B1 motor in his Cuda. Might ask Brain Sloan about it I think he knows of the particulars.

Andy, if I wasn't in college, I would be on the phone with you now but it will have to wait. I might however slowly pool some stuff together and maybe have it ready to go in three years or so. I hope that I can also find someone parting out a Duster that has no idea of what valuable. I then can get my hands on all of the factory equipment needed to bring our bracket super pro car back into Super Stock legality. But it all takes money which I'm not in excess of at the moment. When its all said and done though, i would like to use our Duster to run GT/"?" and since some of the 70-72 cars were equipped with fresh air scoops, I can use on of those scoops on the car in the future.

Sounds good! I've looked at the different years 400 combos in the guide and the 77' looks to be a great option at a 315hp factory rating. Depending on how light we can get the car by that time, I would like to run the lowest weight class possible. Oh yeah, Mr. Andy, we have about three 400's at the house that are within the +- .07 that NHRA allows. Now I need to start saving for some 300cfm capable 203cc runner 452's, titanium valves and valvetrain components, and that oh so wallet friendly jesel rocker arm system unless somebody offers something very close to that performance level. All in all, its gonna be a well traveled journey to the track. Hopefully sooner than later. Maybe I can bump into the right investor at the right time and God can pour some blessings(in form of sponsorship) down on me from that "window" lol. Again thanks for all the info guys.

I don't have any, I got to know Joe after that car was gone in 1975 or so. That car was a Car Craft or Hot Rod magazine "How to build a SS car" project car, they where going to change it to a 1971 RR and put a Street Hemi in it for SS after the 400 build

The smogger 400 ran so good they didn't do that

Bobs current engine is a stock 400 block that is half filled and uses a stock 383 forged crankshaft. We run good steel billet main caps "pro-gram" and aluminum GRP rods. The engine goes through the traps at 9200 RPM. Its been a few years and the engine is still running pretty good. It goes 9.20s @ 143. I did pull the pan to inspect the bearings once and all the bearings looked perfect. However there was still some evidence of "Cap Walk". Still going though.

We used Hemi 6.965 long rods when that motor was built. That trick let us use an off the shelf JE piston. So that makes it a really long rod motor. Smokey would love it. Not sure if was Dwayne's heads, the roller cam we ran, or the long rods, but the dyno numbers were healthy.

Thanks Andy! Those have to be some light pistons
