Asking this for a buddy. The vortech supercharger that jegs is selling, part # 933-4GP218-050L is that any good? his motor is a reman 350 from GM. Its bone stock. He plans on slowly building it up as time goes on. But already baught that supercharger. Would this be something he could bolt on and beat around on and build as he goes or should he build the motor first? Its a street car. Its a 1986 chevy caprice wagon with a t10 4speed and 3.73 gears. Thanks any help would be great
