How much power will it make?

"I used this very same cam in a SBM 416 with 9.2 to 1 and it made 517hp 510tq the 440 will make more power than that."

Mike - As stated your reference has no bearing on the engine or cam in question unless you ignore the basic differences between the two. How many of your engines using this camshaft were big block? What heads were on those and what did they make?

I'll admit, my numbers tend to be on the low (or realistic, depending on how you look at it) side. I'm familiar with dyno testing and numbers and I base mine on what I believe it will do in the chassis. My sim programs (Pipemax and Engine Pro) put crank power around 550hp and 550tq but these are designed to mimick dyno results. I don't think with twisty headers, a full exhaust, running at 190° or more, and an accessory belt driving the water pump and alternator that it will make close to those numbers.
