stock small block
Are you sure you want to do this? Is the bottom end stock? Depending on which intake manifold, heads, headers, carb CFM, etc., you could make up to 460 HP at 6000 RPM with the XE274H cam. This sounds like shrapnel time to me if you don't go with a good crank, rods and pistons!
Look at some of the 383 engine kits on line to get and idea of the possibilities.
