Been a looooong time. I'm about to tear into my Plymouth again. It's been garaged the last few of years due to a wicked shimmy in the rear. Figured out finally it was bad pinion angle... or more accurately, zero pinion angle. My rear springs flattened out completely.

Anyway, I'm redoing the rear suspension. While I do that, I'm swapping out my 3:90's for 4:56's. I want to swap out to a single plane intake. But I've been out of the game for so long, Mopar discontinued the M1 intake whiney

So, what do you guys suggest? Block is a .060 over 383. Heads are 456's, ported... but I'd have to dig up my flow sheets to tell you what they flow. I'm running a .528 Mopar cam & a Holly 830DP Mechanical. An Edelbrock Performer RPM is currently installed w/ an Edelbrock Performer RPM nitrous kit.

Any suggestions would be awesome!
