Hey guys, been busy working on the car. Took the stock 7.5" out springs and shocks. Going to a 9" or s60 still in the air on that one. My question is what for rear suspension should I run for drag racing? I've read alot for stock type springs and double adjustable shocks will get you a long ways. I'm looking for end result of 800 hp. Car will be a street/strip wagon. Wasnt sure how much different a 4 door wagon would be vs 2 door coupe. Any info on the rearends/ suspension would be greatly appreciated. Thank you

I would go for the 9", preferably one that has raised ears on the rear to change the instant center of the suspension. But, I would look into adjustable upper arms, solid lowers, an Anti roll bar, and double adjustable shocks. I think that stuff will get you on a good start. But just as important as the rear is getting the front end to move to transfer that weight. When you put the roll cage in, tie the back bars into the upper spring seat pockets to support the load.

As of right now front consists of v6 springs and 3 way adjustable shocks. I've read that'll work just as good as trick springs?

If the spring rate is right they may work. You can give it a shot, it’s easy enough to change later. I had trick springs in my chevelle from day 1. I went through the 3 ways, to koni spa-1 shocks to strange single adjustables on the front.

800 HP gives a lot to think about. My first thought is getting enough tire under the car for the HP. Your going to need a good cage, the G body frame needs help. If your staying w/ stock rear set-up the mounts need help. A good sway bar. Check out S & W Race Cars and Trick Chassis for ideas.
