Dyno testing a stock(?) 1972 440

Whiplash and thmprs aren't anything new. Been doing the same thing with cams for a lot of years in low compression engines. You get a 108 or shorter LSA and smack it in ahead at 100. Tricks the engine with increased cylinder pressure. Plenty of low compression 360's run damn well with a 284/484 in at 100. And I'm sure the peanut gallery will say what about fuel economy or some other stuff. If you want fuel economy, stick with the stock stick. It's about making things work with what you have.

If you think that you'll get a 420 lift cam with shorter duration to run with a 484 installed at 100-102, Ummmm NOOOOO!!!!
