even with a set of 1 3/4 headers, you should be at and over 500rwhp. You can build the badest longblock all you want. Be perfect on all of your tolerances, specs, so on.

But your cam is what's going to determine how that motor will work together. I think you should be fine, actually your combo is very near to mine, it was built a year and almost a half ago and i have a twin with the same combo, but through a m6 and he makes 538rwhp, 470 rwtrq.

Your heads are from ETP...well, we have alot more in common!!

Good luck, you'll be fine..dont worry to much on the numbers, just get your driving technique becuz you'll need to relearn how to drive it.
