Yep UMP is pretty wide open, no aluminum blocks, no mag's & no dry sumps. Everything else is fair game. Rollers, Dart blocks, SB2.2 heads etc etc.

Although one saving grace in UMP that i see is people over powering there cars, i see that alot. Then they are constanly detuning it to run on dry slick.
