Well.......”IMO”(which is all it is without testing the theory).......there is likely some power/performance left of the table with that cam, in that combo......especially in a heavy car........and even more so if it’s a footbrake combo.

How much power? Who knows.
Maybe not even enough to justify a change.......but I’m pretty confident there’s a cam that would be better in that motor and car combo.

I just freshened up a set of 572-13’s that came off a 588 from a well known mopar engine builder that had already made pretty big numbers on the dyno. However the owner wasn’t thrilled with a few aspects of the way the car performed, so I made a few changes to the heads and he had a different cam done for the motor........and we’ll have to see how those changes pan out.
