i have the ignition takin care of, i have vortech heads, and i am running a 750 on top of a edlelbrock rpm manifold. I'm not sure on the iron pistons.....still checking on that.

If i put iron pistons on would that drop my compression.

I also am not really up to boring the block, but .030 over with a 400 crank would get me a 383, would it be smart just to put a 400 crank in?

I know 900 may not to easy i want to get as close as possible.
