This is the O.S. Max 30VG(P) Rear Exhaust Monster Truck Engine
                    with the new 21E carburetor (OSMG2493).

FEATURES: Same mounting dimensions as .21 size engines making upgrading easier
          Advanced Bi-Metallic Liner (ABL) cylinder liner construction
            This process uses a double layer of plating material rather than
            one thick layer. This helps the metal bond to the cylinder and is
            more durable. Also, the plating process is more consistent,
            resulting in a more precise fit between piston and sleeve for
            better compression and longer life.
          Machined aluminum piston, 3-port cylinder liner and double bushed
            knife edge connecting rod
          21E single needle slide valve carburetor (OSMG2493) with insulated
            sleeve to prevent fuel vaporization
          SG (pilot) type oversized crankshaft with rubber-sealed front bearing
            and oversized rear bearing to handle high torque loads
