Thanks Andy, yeah I've got a 427" sb Ford with heads that flow just over 280 and it made 511 but with a lot less cam than this one will need.

I gotta try to shift the torque up to a higher RPM, I know a few tricks to use on the Victor intake, my gut still says the 370" 3.55 stroke is a better fit for the short wheelbase Rocky but I've been itching to do another big arm SB Mopar since I first took a ride in Tom's F.A.S.T. Challenger.

I'd love to find a worked set of W5's under my workbench somewhere (like the old days).
