Quality, performance, power much better than OE. Easy tune. Does not overpower but enhances and potentiates the overall driving experience on the Revo. Included exhaust manifold and reuse of stock (or aftermarket) clutch assembly make for a easy upgrade. Racing or bashing you can't go wrong with this drop-in engine.

O.S. .21 TM Monster Truck Engine with Revo/Slayer Manifold
I bought this motor and installed it...I broke it in really slowly and easy...then tuned it in and this engine pushes my revo to its limits , over the limits lot of times.. this engine is very quick and fast..once I got it tuned in I have ran it for 3/4 gallons of fuel and haven't (had) to adjust it any..two times I could tell it needed to be leaned a hour cause of the heat outside..it would have still ran good had I not have tuned it in..never ever have to set Lo speed needle or idle again..it holds its tune as well as a few of my hi end Italian engines bb's also... They cost more than the 3.3 but for the ease of tuning and the tremendous amount of power you gain makes it worth it everytime you pull the trigger..you have no chance of goin wrong..
