Blower has sixty degree cast GM small bore rotors that ride in precision ball bearings with helical steel GM gears to insure accurate rotor timing and work well for engines that are under 500 cubic inches. The blower uses double lipped rotor shaft seals with billet alum. bearing plates, a billet front gear cover for maximum strength and gives the supercharger a superior polish. This blower case is cast alum. TBS with the bottom outlet being machined to help keep the airflow in the blower manifold and one of the best polish jobs on the market.
Blower includes a pressure relief valve as well as a oil sight glass. A single or dual 4150/4500 carb. adpt. can bolt to the top of the blower. The blower case has the extra length added to the front of the blower case so the buyer can still fit a small cap distributor or magneto in the rear with no clearance issues on the supercharger.
Blower puts out 360 cubic inch's or air per revolution of the supercharger.
