any guesses on the hp and torque




Just built an Indy headed 427 sb a couple of months ago, Indy 230 heads I ported on a bit, Indy intake converted to 4500, 1050, 14:1, cam was 272-278@ .050 and .765-.710 gross lift.
It was 4.125 stroke, 4.060 bore and used TTI 1 7/8 x 3.5" headers...it made 726HP at 7000rpm and 590's TQ. Martin owns it, he's a member here. I think his handle is w2 stroker?

Anyway, this build could have used better heads and headers, larger carb and more camshaft for a more serious effort but having said that....it was a bracket engine that needed to make more than 700HP so that's where it ended up.
Personally the Indy heads need the short turn revised to allow a different S/T shape...until then they will never live up to their potential.

I'd guess your build will be somewhere around 620-640.
