what stock eliminator class?

[James L Miller]

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.

Just checked, no seats cut
