"That discussion was around the 724 intake which is the B version of the 725 intake that I'm running on this motor. Those are the M1 intakes with standard runners and 4500 flange."

It was nice to buy the intake for $81 during closeout.


"Still no one makes a RB (or B) dual plane with 4500 flange. I'd run one on this motor if it was available."

I would send you my CH440 to use but someone trashed it in a magazine article and I can't hardly give it away.
