I know it doesn't have the torque/and stroke of the RB motors, but if it falls in the H, I, J area, (like I think it might), I thought It just may have a crack at being competitive, Thanks for any info.

Sounds like a neat car.
Now, time for a reality check here.
That combo has been de-factored 49 horsepower. If you can't put something together reasonably , that will run under the index , then Stock Eliminator is probably not for you.
On the other hand, if you want to run at the top of the pack and survive a heads up run in those heavily populated classes, it won't be cheap.
Tommy Auger's car is a top end piece ,as are the other fast 383's out there.
There are guys here that will help you to do it yourself, and also plenty who will help you spend a big pile of money.
You need to think it over and tell us what you want to do.
Also , where are you located?

Thanks so much for your info & help. We are in southern Ohio. Very fortunate here; close to Trails in Columbus, Norwalk, Quaker City, the new 42, Mt, Vernon, Magnolia, Marion County, or Larue. Wanted to write more, but could't figure out how to edit, but, how much of a detriment do you Chrysler guys think those little 516 heads & tiny afb, I know I have to run, would be? I'm just not slippery enough to know how to figure out how to get a set of 906 heads, a late model intake & a Holley past tech. LOL! (Bet it would run then) Thanks again. Bob

Build a Pure Stocker so you can keep it streetable.

If you're willing to throw some money at it the Edelbrock 60917

aluminum head is a legal stock replacement.....

Oh, the heads aren't the greatest, and the carb's too small.
That's why its got 49 horsepower off it. Don't think that's enough?

Out of curiosity, is the car a Hardtop or a Sedan? My Grandfather had a brand new '65 383/330 Sedan. It ran C/SA then!

I agree with Mark also, if you think the 516's and the carb are detrimental to the combo, you need to rethink your plans. Plan on spending most of your money on the heads. It's not going to be a "dime rocket" for sure, but it also shouldn't break the bank to build it and be somewhat competitive.

I would think the bowls in the Edelbrock exhaust ports would need welded up and smaller seats put in for the 1.60" exhaust valves. I guess since they allowed "any valve job", welding the area under the seat is OK and then remachined? Or do you have to leave a big step under the seat since welding isn't legal on a Stocker head? Is the NHRA legal head coming with valve seats installed? I think they were, not sure if they still are.

The 915 heads are better than the 516 heads. Those 915 heads are from 1967, where two versions were produced by Mopar, one with a 1.60 exhaust valve, the other with a 1.74 exhaust valve. Of course, you have to use the version with the 1.60 exhaust valve. Dean Oliver does a great job setting up the AFB for stock. We used CP pistons, which were flawless. If you can afford it, use the legal aftermarket rods specified by NHRA.

A few years ago, I wrote a Car Tech book, with huge help from Jim Hale, on building a 383 for Stock for my someday soon '66 Coronet stocker. It might help you decide if you want to run a 383.

Not totally sure but I think those E heads come with the small ex valve and closed chamber. The reason so much has to be done ($$$) to be like a 906. I have a 65 4door Plymouth (273 or 383) that I've been thinking what if...

"Combustion chamber volume: 75cc / 84cc / 88cc
Intake runner volume: 210cc
Exhaust runner volume: 70cc
Intake valve diameter: 2.140"
Exhaust valve diameter: 1.81"
Valve stem diameter: 11/32" "

I think someone said they weren't cutting the seats, so that would help with the standard 2.08"/1.74" valves. Then you need to ream the guides for 3/8" stems.
