It’s smaller, lighter and offers several mounting options. Perfect starter for race cars with clearance problems in the chassis or around header pipes. Chevy 153- and 168-tooth applications. Starter has 1.4kw permanent magnet, weighs just 9.6 lbs. and includes bolts and shims.
Tech Tip: Due to variances in design between manufacturers (Flexplate, Block, Starter, and Crankshaft), you may need to install or remove starter shims between the starter mounting block and engine. If the starter is engaging too hard, install shims at the mounting point. If there’s not enough engagement, the starter is not catching enough teeth on the flexplate, and you’ll need to remove the shims. Some starters also have shims between the mounting block and motor to adjust the reach of the gear to the flexplate.
