Paul,
after trial and error, carb tuning, lots of tuning, and lots of followup research online, with software programs, etc... I reluctantly stepped back down on my cam. I just removed a very similar profile solid lifter cam after 1500 miles on my brand new 428 CJ motor. Same valvetrain, same intake as yours, etc...only I use E-brock ported/matched heads.. I always wanted to try it and see in the FE what the bigger cams would "really" do. To me, It's a waste on the street when the true power band doesn't start to really kick in till it's too late. How much time do you spend driving your FE at 6000-6500rpms on the street?. After trying 4 different solid lifter / flat tappet cams in my last two FEs, I ended going with a custom grind (stepping back down in duration and lift a bit). I thought I had power before, not so. Wow, what a difference now. Found the sweet spot again, and it pulls like a freight train in any gear 2k-6k, down low, mid, on top, lugging it, whatever. If it were me, I'd be changing that cam out ASAP before the motor goes in. But, that's just my .02 cents after trying (4) different cams now my FE 428s with identical drivetrain configurations and vehicle weight. Bigger isn't better in this case. Good Luck.
