COMP Cams Nostalgia Plus

As I would not argue this point , I believe Comp Cam took advantage of timing when the purple plus series was developed many cam companies were convincing the public that their old single patterns were obsolete a point that was argued by many top knowledgeable cam grinders. But by taking a winning cam grind such as the purple shafts and putting a marketing ploy of improving it by making a dual pattern cam(more modern cam )out of it they were trying to sell Best of both worlds.

Man, I've had a few, and rode in some Badass Mopars that were dailies, with the ol Purple Shafts in em. They Work, darn it!
 
In my experience, the Comp Purple Plus cams are better than the original Purple Shafts, and I have had good results with both. We built a 367" (.040" over 360) with FM hyper/cast 4 eyebrow (9:1) pistons and ported "J" heads (2.02" intake valves) and a "292/.508" PP Comp cam using Rhoads V-Max lifters. I felt the cam (duration) was a little too big, so the V-Max lifters gave me a way to calm it some at low RPM. Using modified 273 rockers (1.6 blueprinted ratio), 1 3/4" Hooker headers, and unported RPM (not AirGap) intake and 750 Holley DP, it ran 7.0/6.90s @96-98mph in the 1/8mi in a lightweight A-body chassis. It sounded like a roller cam, and revved willingly to 7000+ with that lifter combo. We shifted at 6800. Also I have a milder 440 with a 284/.484" PP cam in it, they really do work well. I'd like to try that smaller PP 280/.474" myself one day.
