## Description

This transmission to engine bolt kit includes all of the bolts needed to bolt most GM transmissions to SBC / BBC / 90° V6 engines. These bolts surpass grade 8 specifications and are rated for severe duty. They have a flanged head to spread the load evenly and do not need a washer. They are phosphorus treated and have a light oil coat to prevent rust. All kits are designed and tested for use with stock style components. In most cases they will work with aftermarket components, but may sometimes require washers due to increased tolerances on aftermarket parts. Please verify correct sizes before ordering. Some applications may have either metric or standard bolts depending on year. Please verify which you need or contact us for assistance.
