Two different motors for two different purposes. The "BOSS 302" was originally designed for Trans Am racing. Those heads had huge intake and exhaust ports not made for low RPM HP. Even when those same design heads were put on the Cleveland, those ports were still too big for low RPM HP. Had Ford made an HP version of the 400 with those heads.......then you wouldda SEED somethin. lol
Even still, the 340 in T/A trim, which was Mopar's answer routinely kicked the BOSS 302's butt and I've always attributed that to the extra cubes.
