Rod length will not make a difference, you'll need about 12.25:1 compression. You're going to end up with what amounts to an average Super Stock engine, but you can use a better carburetor and get there easier. You could use any good shelf stock closed chamber 427 piston. Should be able to get one from Wiseco or JE, for sure.

I found one of my cams but the duration is over 300 .748 .748 112 cn for 250 shot of NOS. I looked in wiseco they have a nice set 4.310 bore. I can use any type of manifold and carb or tunnel ram. Going to scan the cards see what you think.

Thank you very much this is just a build I have always wanted to do for the heck of it. Slick Rick is doing my 291 heads,
