well, if you really want to compare short blocks, I'll need 3.55 gears, 9.5 converter (against your 4 speed), roller rockers, 2.02 installed in my home ported 596 heads, cam change, I'll have to add 5 cubes by boring it .030, you'll have to add 100 lbs to your car, and we'll even leave the tunnel ram out of it. (you really wouldn't want this race.... :D )
