Thanks everyone! I will definitely report back when I get around to tackling this project and find out where the pistons sit then work from there.

What do you guys think about carb after I do the top end/cam swap? I figured I'd go with a 750 demon as I have heard good things about them. I have a Holley Street Avenger on now which is too small and seems to be killing the top end. Would I benefit power wise with something like a 4150? I'm not really too concerned with street manners and gas mileage, as long as it CAN be driven on the street I am happy. Doesn't need to feel great, I just want to get all the power I can out of it on the track.
