Would like input on a build sheet for a Cleveland with 4v heads. Looking for bullet proof and fast. I've built some small blocks but this will be my first mid. Not concerned about gas mileage and am aware of the higher rpm necessary for real horse power. I've already picked up some parts but would like any input as far as cam, pistons etc.
thanks

Do you already have the engine, and what's the goal for the car? Street car, weekend warrior etc. Do you want to be able to drive it every day? And you don't need a lot of rpm to make power. Port tongues in the 4V heads with a good roller cam and all the other crap and you could make 400hp without the engine really having to try. With good aftermarket heads like CHI you could make over 500hp with a street friendly setup. That's without having to even stroke it.

if you have stock 4v heads i'd use the good port tongues that you have to screw/epoxy into each port instead of the intake gaskets that have the ports built in. then do some bowl work and clean up the short turn radius on the intake and exhaust and you'll have a great flowing set of heads.
