UT3 GX120 Quarter Midget Nascar Youth Series USAC25 QMA POWRI legal engine

Brand New UT3 GX120 engine, prepped for Quarter Midget Racing. This is the same engine as our Heavy Flywheel engine. Without the super heavy flywheel. This would have a flywheel over 1620 grams but less then 1700 grams. WE WILL NOT SELL light flywheels on engines! Light flywheels slow your lap times. All light flywheels are removed from service. Cam timing, ignition timing, compression is all optimized for best performance. Engine includes Billet Air Filter adapter and billet throttle linkage.
