How long did they last with a stock block @ 1000 hp? :dw:
Considering most well known engine builder's use similar engine parts with there own builds, pretty damn well they hold up. look on MMR or Lethal etc, they use Manley H- and I-beams and ARP hardware for there builds, and there going over 1000hp some of em. if they were shit no engine builder would use em. Like I said its all in the tune. having your timing/ A/F whatever the case may be slightly off and there goes your motor, no matter what hardware etc you have in it.
Actually they came with Zollner Pistons.
thanks
