With a shorter 4.125 stroke the 482 using the Edelbrock heads at a 234 cc runner volume made its peak power at 6900 rpm with a 279 at .050/.704 lift solid roller. With the new revised combo and using the bigger High-Port heads John's motor made it's peak power at a lower 7000/7100 rpm with a 285 at .050 /.850 lift roller.

(I'm trying to keep my new street 505 under 6000 rpm. Should dyno next week)

Don't know where my Desk Top sheets are at the moment but it sems it showed a peak HP(7??) @ 7,400/7,600 RPM.
Jack has told me his predictions are about 7,000-7,300 for shift points..
It's going to be a HO tractor motor !!
Think I just graduated from "streetable" motors....
