I have a 1970 350 small block. The block has been machined, decked, linehoned, and bored to .030. I want to get as much HP and Torque out of this thing as I can and that includes stroking it. The engine has 4 bolt mains in it. I will be starting new with crank, rods, pistons, everything. I will not be using the stock heads, I have read in this forum they are too small.
