NMRA is putting on a 2 race deal (BMP and IL I believe), where it's a limited rules (weight breaks mainly) 10.5 tire class, no holds barred (or close) on engine combinations. Vortech has stepped up to the plate to sponsor it.
Here's one thread that Chris Derrick (aka Mud Duck for those of you that have been around for a while) started on the whole subject.

I think they're going for the Clash of the Titans type shootout, if they pull it off (i.e. get the rules out on time and not drag their feet like everyone is concerned about) it should be quite the show.
