Question 3-4 clutch stack

What is the best stack ? For 4L60E I got a kit and it only came with the standard 6 stack.
So I want a stack that's going hold up to some power a proven stack.
I have a lot of New Hard parts and just need a good proven stack to finish my build. THANKs

My builder recommended a Z-Pak. I don't know which one is best and I know some people have their favorites. I went with what he suggested for my power level.

The stock Zpak (14 one sided clutches) is ok, but the modified one (16 one sided clutches) does better, and is pretty much equal to the Borg Warner Hi-Energy 8 clutch setup. The Borg Warner Hi-Energy 9 clutch would be the best in terms of holding power. I've seen the Borg Warner Hi-Energy 9 clutch setup in a few nine and many more ten second vehicles do well when used along with the modified TransGo Performance Shift kit.

He's right, and to be honest with ya stay away from the Z-pacs all together as they are crap for anything over 400 hp. If you stick with the Borg Warner high energy 7-9 pac setup you should do well.....
