Has Jesel belt drive, bullet cam, Jesel valve train, comes complete with megasquirt fuel injection set up tuned for Vegas. Comes with downswept headers. Headers custom made. Motor has 20 passes on it since it was freshened up. Comes with water pump, vacuum pump, crank trigger, starter, alternator. Made 700 hp with a smaller intake and a 950 carb.
