Nice choice. And I agree that the cam the OE poster has is a nice street cam but way short by 20* @ 050 for making a 500 HP run and at a min.
I also agree with Mopar and Stroker, but then again, you want what? That is the bottom line here today. Though I'd think twice. (Then again, I don't. LOL! :burnout: )
Your engine builder wants you to take advantage of the CNC ported heads with not just duration, but lift! This is why you spent the money on a CNC head. To get the most out of it!
