It is also slightly longer in lenght than the 1.9hp starter. Aeroflow starter motors have high heat resistance and are powdercoated black for extra corrosion protection. Small & Big Block Chev XPRO Super Torque Starter.
This starter is a great upgrade on my 86 C4 Corvette, It will also help for any engine upgrade or extra compression. Just had to add the 2 shims provided and a little adjustment to the cutout where the sump pan goes. Very strong unit.
