for a powerplant, you could go with a stroker (451 or whatever) running 13:1 compression on E85 with a quickfuel E85 carb. big block B or RB with aluminum top end weighs about 470lbs, or a bit less than an original all iron small block

with the chassis set up right, light car, powerplant you would smoke him.

i dont know about getting your cuda light enough, but it might be doable. abodies get a head start on weight reduction.
