I'm getting ready to test a 280/270 480/460 lift cam on a 109lsa on a V6SOHC 3L VG with 8:5 CR and a target boost of 30-35psi on a big ball bearing hairdryer. (61degree overlap)
what are your guess of its manners?
I've been told by 50 experienced ppl to use high lsa and another 50 highly experienced ppl told me low LSA. soo.. Its all in the air till you test it. I also read somewhere that a poor flowing exhaust manifold will benefit from a low lsa (I need to find that link again.)
My last cam had 50degrees of overlap and was awesome! but it was on a 112lsa which doesn't matter as it was still at a 50degree overlap. Also the Cam Ron Isky reccomed i used showed a 56degree overlap.
