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.

How much boost/power did you end up making with the stock engine?

The quick pass was on 16 psi. It'll make more but goes slower, all out of turbo. With some fuel pulled out of it I think I can squeak some more boost out of it. And add some timing too. It's a very, very conservative tune.
On the stock stuff it had been 10.50s @ way less mph and a ton better sixty. I forget the mph, sub 130 though. I want to say it was at 10ish psi. It was picking up big power with timing increases but I was afraid of the stock stuff.

I've got a 76mm T6 that I was going to build an EZ headed 400 from parts I have for my Coronet, but thinking more and more about the 5.7. I'm interested in just taking an OEM pull out and starting rather than building one, don't need crazy power (yet). Just a step up from my Fury's very docile turbo setup.

It's on holley HP efi. I went with the cable drive throttle body so that I didn't need the Dominator. Kind of wishing I would have sprung for the extra money now for the extra inputs and outputs.

Thanks! For autocross and street I've got 17x11 C4 Corvette ZR1 wheels. Cheap and effective. And 275/40zr17 Continental ExtremeContact Sports. It's a tradeoff, I could go a bunch bigger but nobody makes a good 17" tire in wide sizes and the 18" stuff gets expensive. It's working pretty good for the budget wheels/tires though.
