Are all small block Chevy starters the same?
Small block Chevy starters are not all the same. While most starters may look similar, there are slight differences that you need to be aware of. Chevrolet developed two starters for different applications: a standard-duty starter and a high-torque starter. These differences mainly revolve around the nose cones and the flywheel diameters. Most small block Chevy blocks come predrilled for use with either starter, which can lead to confusion .
The high-torque starter is designed for engines with high compression, significant initial timing, or hard-to-start engines. It provides more torque and is generally used in applications where there is limited space, such as tight header clearance or kick-out oil pans. The standard-duty starter, on the other hand, is used in other applications.
