Reportably the KRE 325 cfm D-ports have about 215-220 cc intake runner volume. With that big cam it will be interesting to see where the motor makes it's peak power at. Any hints from the computer program ?
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)
