LS GM motor in your mopar, 1000 hp no issue and crazy fuel mileage. I call total BULL S#!%. I have been around too many of nuked ls bottle bombs. Take into account the $3000 tpical running engine price
and compared to late hemi cylinder head flow the ls is meager at best. The valvetrain is really to weak to support a serious spring setup without a $2700 jesel or td rocker system. Unless you buy a ls 7 or 9 the heads aint great just ok. You know there are plenty of magnum truck motors with hyd rollercams and blowers pushing 1000 hp too. KRC perf pulled this off long ago. Down with ls crap.
