Now if you went with a ported head and roller rocker arms that maintains better geometry at higher lift then I could see either cam working well. Not to mention they are harder on lifters because you need stouter springs to control them.

So basically the cam above with a standard dual spring(btr platinum) and LS7 lifter is a recipe for valve-train failure within 20k miles.

Call kip at cam motion and tell him what you are looking to do.

Opps. Do I have to concern about the issue on Lt1 engine?
