Too much lift on either for stock heads and rocker arms. I would personally keep the lift around .600 with stock style rocker arms. I don't understand why companies are producing these extra high lift cam shafts when valve guide scrubbing is a issue. It was a problem on LS and I don't see anything has changed to address it on LT. 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.
