It's got the MMX drop in piston/rod package. I actually didn't even figure the compression, just slammed them in and sent it. Quick and dirty. It didn't really need them but I just felt more comfortable having them for Drag Week because I'd be so far from home with no backup plan.

I actually put another Hellcat clutch in it a couple days ago. Not sure that it's got enough steam to go 9s but it keeps getting faster so who knows? Definitely didn't expect the 66mm to make as much power as it already has.

It's just a shade under 4000 lbs usually. Was 3960 right after the 10.38 pass.
