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.

at this point i see the hydrarev kit as a bandaid instead of a solution. id change the springs out first then if your really gonna beat on it up to max rpms id look into the rev kit. those are my thoughts and how id do it personally.
