These are rear exhaust and devloped for mainly Monster Trucks.They are the largest displacement in the O.S.line up for model cars and offer overwhelming torque and power.The new 21E carburetor is a single adjustment type and fitted with a thermo insulator.It offers stable running.
The engine mount size is the same as the 21size and easily replaced in most models.
