Cam Theory and Application

DFX 340 Duster said
Keep in mind that 69 Cuda is quoting from a 1975 magazine! A lot, if not all, of the racers back then would withhold certain amounts of information regarding their setups and tuning tricks. Same went for the cam manufacturers.

Absolutely correct, DFX

Getting Camshaft information, even from the Factory Techs
at Chrysler Racing was 'near' impossible.

As for 'Crackedback'

Just how many guys could 'tweak' a customers Race Car at the Track.

And there were virtually no 'Test-n-Tune' Tracks.

In the Northeast, you had to have a 'Bear Chassis Dyno', as that was the only
way you were getting the 'optimal' performance, at least on the
Street.
