LRP 28 Spec 3 or its close cousin the Dynamite Big Red 28 + a JP-4 pipe. (Lots of other pipes would work...)
The car is an Ofna DM-1.. - like this one... I think. It has a shock conversion if so. Not sure if 1/8 or 1/7.. Anyway, looks like a DM-1. And that engine combo is wicked in anything 1/8, including MT's...
My only gripe with the DM-1 is the absolutely stupid clutch bell design. You need to get an Ofna shim kit and go ahead and order a tenner of the small baby front clutch bell bearings..
