Engine was completly done by Split Second performance. It started out as a 670 and was bored out to 703cc's. It has been race ported and has 46mm carbs on it. The compression ratio is form the heads is 13:1. Pipes for the engine are custom hand made pipes from Neil's Power Pipes in Edmonton and were made to fit in a Rev chassis. The engine put out 152hp and 94lbs. of torque on the dyno. Fuel for the engine was Vp's C12. I am open to offers on this engine.
