440RB INDY DUEL PLANE OR RPM INTAKE HELP

IQ52 said
I don't have the 440 M1 single plane to measure. The carburetor pad height on the 2D Indy is 5.25" and the pad height is slanted on the RPM, 4.90" front, 5.80" back and 5.35" in the middle. The Indy is a really good manifold and is more designed for a Max Wedge port.

I would really like to see you get your 700hp, but the cam may be a little small for the rpm's necessary.

Yes the EFI stuff works. We've made equal to or a little less horsepower with the EFI. Certainly not enough difference to even worry about.

I have been reccomended to use the holley stealth 550-440 .
I was told you can tweak it by turning up fuel pressure if engine make 600 to
