Cam choice!

I think one thing that is missing from most of these LSA vs idle arguments is overlap. For those going for stump pullers and low overlap (equates to duration) it is not as important I don’t think. Those who like the longer duration numbers (more overlap) the argument becomes more valid.

from Vizards techniques you don’t pick durations. They fall out of LCA and overlap for what you are shooting for and the duration is what it is. My 225 has low LCA and low overlap and idles smoothly and pulls plenty of vacuum
