GMHTP had a 383 with ported stock heads put down (uncorrected) 448.5 at the crank. I have AFR190 street port. Not sure if this is better or worse than the ported stocks. Find out Thursday. My hope when I started this was 400 HP at the wheels. Wish me luck.

how does it idle and drive? should do very well with that. the package holds more potential for sure. yes that cam is very small for a 383, but after what you did a cam change isnt too hard. so heck yeah get out there and smoke some tires
