I meant to say that I only posted my old combo just to give you and idea of how another combo close to yours ran so it might help you compare things with yours. But I did forget to tell you I had the MP .557 cam in on a 104 installed centerline. Hope it might help you some and good luck with it. Ron

Thanks for the info Ron. I'm debating on advancing the cam only because I need more top end power than bottom end right now. My understanding is advancing the cam will do just the opposite. Thoughts?

Why are you shifting at only 56-5800? A 250ish @ .050 cam in a 440 should be shifted about 1000 rpm higher. Also, you mentioned swapping to a 1.6 rocker (assuming roller), but what are you running now?

Anything over 5800 and the car slows down across the board. As I type that, I think back to Cab's comment about fuel or other scenarios that I may be overlooking.

Rocker arms are 1.5 rollers.
