Why Are Edelbrock Cams Unpopular

You can't get the Performer RPM cam in a Summit grind. I couldn't find a summit grind with .488/.510

The regular performer, yes, not the higher lift/duration RPM grind.

THey don't list it on their website, but I'm sure you could special order it. Look at the specs for the SB Chevy Performer RPM vs. the Summit part # SUM-K1107. The grind is the same for a SB Mopar.
