Just a quick question. I have a crate Hemi with the duel plane intake and I have a chance to switch to a single plane one off of a 528 will it be an overkill for my motor? And the guy who has the 528 wants to try the duel plane one how well will it work on his? Thanks



I ran the dual plane for a couple of years on a 472 street hemi with old Mopar aluminum heads and a K8 engle cam. Although it ran OK, I struggled trying to get the fuel distribution equal. The plugs on the same plane were always different colors.

This year I went to Stage V heads and intake with two Edelbrock 650s and a small roller. The plugs are tan, all the same color, the engine response and power is much better, it gets better gas mileage and was still able to make 658HP at 6500rpm.
