The power for climbing. The speed for racing. The engine for both. Torque — or speed. Time was that an 1/8 scale engine was designed for one or the other. However, monster trucks and truggies need both — and that requires the O.S. 30VG.
With its virtually perfect balance of bore-to-stroke, the 30VG offers unrivaled adaptability for 1/8 scale and the perfect power plant for almost any application. Put it in a monster truck or truggy and it excels. Put it up against .21s, .25s and .28s, and it blows them away in big-block performance — and drops into the spaces they occupied for easy, no-mod retro-fits.
Engineered for 1/8 scale — designed and tested for O.S. dependability on-road or off.

Savage owners can upgrade to 30VG power and speed with no mods and minimum work. It's not only designed for use with the Savage clutch assembly, but with the Roto Start Ignition system, too. |
