As Cobra II pointed out in the thread about the UNOH modified, UMP rules exclude the only V-8 Toyota uses in their production vehicles:UMP 15.1 – EngineA.) Any American made engine (yes they are assembled in the US) will be permitted as long as the rear of the engine bell housing flange is mounted at least 72”-inches forward from the center of the rear axle. The engine offset must remain within two (2”) inches of the center line from the cross member. The minimum engine height when measured from the ground to the center of the crankshaft is 11” inches.B.) All engines used in competition must be able to be used in a conventional passenger car without alteration (none of Toyota's cars are V-8 powered). Alteration of motor mounts will not be permitted. Alteration of the castings and/or fittings will not be permitted. Any machine work on the outside of the engine or machine work on the front or rear of the crankshaft will not be permitted.C.) Aluminum blocks will not be permitted. (All Toyota truck V-8s are aluminum blocks.)Once the UNOH car replaces the Chevy engine that is powering it to victory lane at Speedweeks with the rice burner that has its decals plastered on the car, I would think every GM/Ford/Mopar team has an excellent chance to protest. Unless some yen is being sent to UMP that pays to open this loophole:L.) There may be specific engine rules issued for each region of North America that deviate from the standard UMP Modified Engine rules included herein. Has any team or engine builder asked UMP about this?
