Instead of looking to squeeze more power out of a 383 why not squeeze more cubic inches into your caR
I appreciate the info, but I already paid for everything to be done to my 383 stroker so I can't turn back now and go with a bigger cubic inch engine, And yes AFR are really good heads and your saying a durtaion of 244/252 is to much of a split, now correct me if i'm wrong but I thought more duration is better especially for some good heads like AFR to get more HP & TQ.
That's what some big performance guys that I talked to told me. They say its not always about the lift its more about the duration that get the HP & TQ.... (In Joe Sherman words)
