MSD 50903 Details

MSD's DynaForce Starters feature all new components beginning with a three horsepower motor. This power is used to crank over the reduced 4.4:1 gear set to deliver great torque to the engine's ring gear to get the engine turning. The compact housing clears most headers and oil pans, but just in case, we made the billet mount so it can be clocked in different positions to help in tight applications. The assembly is powder coated black and will stay looking good, even though it's underneath your car.

Features:

Fits Ford 289 and 351W
Black
Mount can be clocked to assist in mounting
Compact design helps clearance issues with oil pans and exhaust
Ball bearing supported armature and pinion gear
Three horsepower motor provides power for high compression engines
Gear reduction of 4.4:1 improves torque for great cranking
Durable, powder coated finish for great looks and corrosion resistance
