got my super chevy motor today was reading that they took an old style sbc redesigned it and put new style ls cam heads and valve train in it and it made more power then the lsx 427 on 10.7 to 1 compression like 630 out of the shoot with some tuning 650 easy hp.kinda cool they are going to produce them so the guys who have to run distrubutors can play using the new head technology...:shots:
