If the motor made 660tq@5600....... that would be 703hp at the same rpm.

I really try not to “race dyno’s”, since there can be a lot of factors that influence the final results, but I’ll put it this way......
If I were testing it here with 2” headers, I’d be looking for 650-660tq in the 46-4800 range and about 630-640hp peak in the 6000-6300 range.

I haven’t run anything yet myself with the TF heads at all..... so just pure speculation on my part.
I’ve added a few hundred rpm to the peaks on my guesses based on the added porting of the heads and the intake being ported.
Otherwise, stroker BB Mopars with short cams and std port heads usually peak pretty early.

The cam is small, based on what the original criteria was for where the motor was going to end up and how it would be used.
If the goal were just to make a big number.......there’s certainly easy power to be made by swapping to a longer duration cam.
