Who It's For

This starter is best for enthusiasts and mechanics installing or replacing a starter on Chevrolet small block and big block engines where a compact, heavy duty unit is desired, including race car builders and street rod owners who use 153-tooth or 168-tooth flywheels. It is particularly useful when weight savings and a billet mounting option are priorities.

Those who should look elsewhere include casual DIYers uncomfortable with electrical or engine work, since the product ships without instructions and professional installation is highly recommended.
