Mopar Performance Purple Mechanical Camshaft - P4120653AE Cam Card

no such animal as the "perfect camshaft".
I hear that; I got lucky on my second pick. I am now on the third cam, which is just 7* bigger than the previous and from the same manufacturer, but I had to do a lot of fudging to finally like it, and it can't make fuel-economy for no amount of trying; as compared to the previous cam.
The first choice cam was not that horrible; it just didn't work with the gears I wanted to run. And, at that time, I was not ready to commit to purchasing an overdrive. Looking back, it would have been awesome with 4.30s and the GVod that I now run. It didn't suck gas any worse than the one I now have,lol.

Gain in one area and lose in another.
You said it!
Having the calculators available on-line, makes it so much easier to get your choices into the ballpark. Once there, you just call up your grinder and let him confirm or nix your choices, or recommend a better match. And you can then stop worrying about if it will meet your needs or not.
I don't recommend cams; I just give an opinion of what pressure and Ica might be complimentary.
