got action at a 20mill t-rex pv motor used. motor had less than a hour on it when it was run lean. needs to be bored out and new pistons. no tranny gears, no clutch, no carbs, whats a good price to pay and what kind of hp do you think this motor will make on race gas. the motor made 143 hp on alky, b4 the lean issue happend. thanks for your good info. also i want to drag for fun and not run alky.
