How much estimated hp?
I've got a LM7 that 0.030 over with flat top pistons. We're going to run LS6 heads and intake. Not sure yet about the cam, but the speed shop I'm working with said somewhere around 450 hp. It's going in a 81 Chevy Luv that weighs about 2400 pounds. Should be a riot.
Give or take around 320 to 340.. th400 eats alot of power.. but hp shouldnt matter.. what counts is times.. take it to the track.. i made 380rwhp with full bolt ons and cam and 4l60e in a silverado
