LSA Question

Exactly right! DV says the 128 formula is the same for all inline valve engines whether they be small ford, Mopar, Chevy, FE Ford, BB Mopar, etc. His tests with “semi hemi” engines of the BBC or Cleveland/385 Ford variety dictates the same formula with “134” instead of 128. So a true Hemi would probably have an even larger number as a staring point. One other thing this formula doesn’t cover is fuels other than gasoline. Mike Jones (Cam King) covers some of the cam requirements of methanol and it’s a worthwhile read for those who intend to race with alcohols.
