Between engine break-in and completely broken trans, it took a while to get the Jeep on the dyno, but worth the wait. :D
Quick details:
PWR 426 longblock
1 7/8" headers
SHR trans
2800 PI TC

Oh, and it was 94 degrees in the shop with the dyno and ECT was around 200, so I'm sure there is some left if it was cooler.

Thanks guys! That was the SAE correction, if I used the STD correction, I hit 500 :D

No supercharger yet, maybe a more aggressive cam. We'll have to see. I'm enjoying it for now.
