Chevrolet LT-1 Flexplate Internal Balance Small Bolt Pattern 153 Tooth.

TCI stamped flexplates for Ford and Chevy applications are .035in thicker than stock, and the starter ring is welded to both sides of the flywheel for additional strength. Constructed from a high tensile strength material, these flexplates resist elongation and cracking. 168-Tooth flexplates have GM dual bolt patterns and are sized for stock 3/8in mounting bolts but can be easily drilled for 7/16in diameter high performance torque converter applications. Ford applications are balanced specifically for their appropriate engine/transmission combination.
