I think the post you're referring to said 102 ICL (intake center line). ICL is different than LSA (lobe separation angle) I think. I agree with your premise (tighter LSA is better for under-valved engines), but is there a company that would even grind a /6 cam on a 102 LSA (and be able to get it to me by end of May)? Not sure if a regrind can take a 108 LSA all the way down to 102 - that's a pretty big change.
In post #31 I was pointing out to AJ the LSA I got using DV's "128" rule formula, NOT the ICL, & it's pretty much right on. The "6681" Purple Shaft I have is 276°/276° .490"/.490" with a 104 LSA & I installed it on a 101° ICL.
