ive seen a few cummins montes and my only issue with going newschool engine/lsx is all the computers and crap and cost cause im going to actually build the engine so it will be fresh and no worries with an lsx swap id find a lower milage one cam it do a few bolt ons and be done with it
and to the not a huge olds fan you cant deny a 70 442 it was a badass ride
