I may have to look at CNC porting mine, I only had 367 at .6 and it was only 373 at .700, so I probably will come up short on power compared to yours. Tim



while that isn't bad, it will hurt on the power. tim, and others out there do some pretty amazing sutff with CNC.

it's just what you want in the end. the 472 has mopar aluminum heads that have been mildly ported, and flow about 330 @ .600. when i rebuild it, i don't know that i'm going to spend the money to have them done, or just call it a day and have it be a milder motor.
