Does this prove David Vizard's 128 lsa formula ?

If You plug that formula in, many of Mopar's PurpleShafts track pretty close to it, & I'm certain Shepard & Co. did enough R&D of their own.

Can't beat 1960's camshaft tech in 2024.......Good to see DV has rediscovered the 1960's all over again for you guys.
