Default Pulling right on launch

I have adj uppers with boxed lowers, all new poly bushings and off the line car is pulling to right.Ido have factory body braces, thinking about switching. I am not running air bags. SEEMS even when heating up the tires car is almost sideways after 5 seconds in the water. Looking for ideas. Running slicks with 8 psi. Car is a 1967 GTO

If I understand this is what your doing ( after 5 seconds in water) you want to pull up to water just blip the tires then move up about 3’ and do your burn out.
Its a possibility you’re getting too much water in the fender wall and its coming back on the tire.

The other possibility is...even with a posi unit, the drivers side tire wants to unload, while passengers tire is hooking. Making it pull to the right. Essentially the driver side lifts and unloads.

Thats been my experience running shock Suspension, with boxed lower control arms and no hop bars ( adjustable upper control arms ) putting in air bags with more air on drivers side although not 100% it help solve the problem.

Another thing that helped, was moving stock shock location. Notice how shocks are on angel were the bolt up to rear end. The sell brackets you weld to rear end, that allows shock to be straight up and down. That helps plant tires evenly, and keeps drivers side from unloading. Some real good 50/50 shocks. Or adjustable ones, just another possibility.

8 psi is to low for a 10 inch slick
Try 12-14 psi
Rear sway bar / anti roll bar would help if your not using an air bag on passenger side.
Be sure to check the rear end is square in the car.

Rich
To check if it's square you need to find and create the centerline of the car and mark that line on the floor or use a string and plumb bobs front to rear of the car.
The rest is basic geometry.
It's all in this picture.
