Sounds to me like you may need to tighten the front shock rebound up some to slow the front end rise. If it rises too quickly, it can unload the rear tires and then the front drops quickly. You want the front end to rise in a controlled manner and stay up as long as possible to keep weight on the rear tires, then come down at a slow controlled rate.

You're hitting it harder, and need to make sure you have plenty of pinion angle.

Re: Needing Help selecting Converter.....
 

I already have 4 degree blocks in there does someone make something with more angle?

Re: Needing Help selecting Converter.....
 

You could stack wedges as long as they don't cover up the pin/bolt that locates the axle housing on the spring. Do you know what your pinion angle is?
Are your front shocks already set tight?

Re: Needing Help selecting Converter.....
 

I already have two 2* wedges in each side, I have added 4* total to the angle and now it only has about -3. Shocks are set to 3/4 Stiff in front. They are Koni SPA1's someone told me to put them on stiff because it sounded like the front was coming up to quickly.

3* down is probably good for a factory 3 or 4 link, but leaf springs tend to need more. Slide-a-Links may do a better job of combating pinion angle change, but slapper bars usually like 6-8* down.
The other day, I saw a 70s Ford pickup driving down the road. When he accelerated (not really getting on it much), I could see his axle housing twist up quite a bit. Granted, he had lift blocks and no traction bars, but he wasn't launching to a 1.5 second 60' time either.
