400 Hp ( Street 318 ) Build !

You can get to 275+ horse with the right teen, intake, 4 barrel, and mild cam. A horse/cube with flat tops and a rumbly cam. With a little porting and headers even more. Teens respond well to modifications. (like most mild engines do) Nothing wrong with a 300 horse 318. Pretty darned snappy in a A body. More power= more fun.
