Overall overlap, or lobe center understanding?? ¿.

I admit I'm "low" on this kind of theory. My strategy is to pick a cam that "someone else" has good luck with.

I still remember the old factory Chev 350 hp 327 cam, sold by the tons to guys over the counter, was a "damn good" street cam "back then" That thing went into countless 283, 301's 327's and even 350s.
