I did the 383 496 stroker for my car, great combo, tons of power! you'll love it, made 590 hp and 615tq, and pulls 16in vac, have over 15,000 trouble free miles, and not easy miles!
The power numbers are impressive but the one that stands out is the Vacuum. That is an extremely good number and it absolutely coincides with the 15k miles you have put on it. Someone has figured out a real nice combo for sure. I myself would like to see some intel but I doubt the builder would show his hand on the complete package....
