I agree that the RPM should work nice for your combo. Mine is a street car and I built a 493 for it. I use the Indy dual plane as I like to race sometimes when I can and it seems to work nicely for my mild 493. But for your 440 cubes the RPM should do nicely. The Indy dual plane can be in standard or Max Wedge ports and it kinda looks like an RPM on steroids. But for the more cubes of the stroker I like the Indy dual plane. Ron
