Does this prove David Vizard's 128 lsa formula ?

I was having a really good laugh and conversation with Mike of B3. He also thought that everyone leaned on this formula to much. While I do agree with both DV and Mike, I see it as a situation dependent thing as to what the car owner is looking for.

I’ve run cams on a 112 before because I knew that it would idle smooth and pull vacuum which is what I was looking for. Not so much the “Massive Power” gains or losses. Just a certain characteristic..

I’ve used a MP flat oval track cam that was a 106 LSA. It had an idle like a lumberjack on crack withdrawal. It was an insane sounding cam. Being in a weekend toy, I did t care much. The cam had a narrow power band and when it was in it, holy cow did that engine pull!

I currently have a cam on a 108 LSA in my 10.5-1, 340 engine.
241@050 HFT W/about .550 lift. It has a snotty idle, just fine for the once in a while driving hot rod. Not an idle I’d use on a actual ride m driving everyday.
