Ok. 383, Muncie 4speed, drag radials, and a 12 bolt with factory control arms.
Let's just say it was not a pleasant experience. It felt like the rear end was going to bounce right out from under the car. Yes everyone says don't do that, but some of us just have to learn the hard way.
So my question to you guys is... How well do the UMI control arms work. I ordered there uppers and lowers to swap in a 12 bolt. And does anyone know what pinion angle to shoot for.

sounds like you need new shocks.

I had wheel hop when I had my factory 7.5. Not fun. Unfortunately only after 2 months I destroyed the stock gov bomb (due to the new 454) so I only got the umi control arms after the replacement 9" went in. But no wheel hop after.

I had a 92 Dodge W250 that did that once -- death wobble! Hit a pothole at 35 mph and the solid front axle started to dance so badly it nearly ripped the steering wheel out of my hands. New shocks and a front sway bar (and an underwear change) solved that one.
