LOSR2200 Losi 454 Engine with Combo Pull/Spin Start. The Losi 454 Engine is designed to produce unbeatable low end torque as well as high-rev horsepower for insane top speeds. Dyno tuned and ported for the highest level of power from the first startup, the 454 big block engine can pull a 1/8-scale monster truck from a dead stop up to speed without a hiccup.
 The Losi 454 Engine is a terrific power source for ready-to-run vehicles, and will fit all existing big-block applications. The Losi 454 Engine also offers the convenience of a dual Pull Start/Spin-Start backplate. Get the engine spinning with a few pulls of the pull start, or use a hand held, push-button Spin-Start unit to ease the process.
