Crap ass 2v PI motors make more than old push rod 5.0s. Also no LS motor makes 700 hp RELIABLY. Any 3v is just fine at 450RWHP. I think to many people belive to much of what they hear. LS motors and 3vs use the same materials for the bottom end so think about it. Some of this perception is probably because most LS guys go to cams and heads as some of their first mods and mustang guys usually go straight to boost. Now who is more likely to screw somthing up or blow a motor? I've have many friends who hate Fords and have LS motor and are only making 450ish at the wheels and are always worried that a rod or rod bolt will break and I've seen it happen. I don't know why but GM guys always seem to have more pride then mustang guys and always try to stretch the truth.
More pride? Why do mustang guys always get so defensive of smaller displacement motors? Its like everyone should be so impressed when a small displacement motor hits the power levels that GM did years ago. Think about it...even Ford knew they had to step up the displacement to get to the power levels of the competition.
