I have a 84 Z-28 and have been working on getting the most out of the 355ci. that is in it. I have the motor at about 375hp. at the flywheel so it should be right around 300 at the rear wheels. Now that I have some of the power that I have been looking for I have to get it to the ground! I have only been to the drag strip once sense I got the car where it is at right now, and it was boing quite a bit of wheel hoping on me which was not helping my 60ft. times. I know that there has to be a bunch of you folks out there that have or had the same problem as this and would realy like to here what you may have done about it. I know that there are some products out there that are made for the thirdgens but don't want to get something that isn't going to be of any help. I looked at some traction lift bars that Lakewood makes but just can't see what good thay could do when the rearend is set up like it is, it seems that with the torque arm that is on it would stop the axle windup if there is any. Anyway if one of you folks has any good sugestions as to what would work well please get back with me it would be greatly appreciated. Thanks NORT

 

LCA relocation brackets are the biggest bang for the buck; then LCAs themselves; then a stiffer torque arm that attaches to something other than the trans itself. SFCs will become a necessity once you start to hook up. The first 2 items should cost less than $250 installed.

I beleive that drag radials are the best bang for the buck traction mod. You only need LCA relocation brackets if your car is lowered and the LCA is higher at the axle end compared the the frame end. The LCA should be horizontal, or parallel to the ground. That being said, tubular LCA's with stiff poly bushings will basically end deflection in these parts.

LCA relocation brackets help a stock height car. With a level LCA traction is good. But with the rear of the control arm lower and the front it plants the tires even harder. When I launch, the back end comes up, pushing the tires down into the pavement. I have 1.5 drop springs and 3.5 drop LCA brackets.
I would do the subframe connectors first.

The LCA should actually be lower in the rear than in the front, not horizontal.
