Quote: The hp BB cams in 70 were 268 on the intake so do you want the same size or bigger?
The modern grinds ARE larger. Because of lift. The old-school stuff was high in duration for a given lift so diveability suffered in the true Hi-Po grinds. Now you can get good lift at reasonable duration. A lunati 60303 is .493/.513 at 268/274 (as I recall---if thats not totatlly accurate its close) Look at the lift of the stock 268 lobes, its not even .480. Modern grinds rock.
