TSP Gen 5 LT1, LT4, & L86 376 CID Rotating Assembly – No Balancing

TSP Gen 5 LT1, LT4, & L86 376 C.I.D. Rotating Assembly – No Balancing

The Texas Speed & Performance Gen 5 376 C.I.D. Rotating Assembly is designed for LT1, LT4, and L86 engine builds. Multiple component options allow the assembly to be configured for your specific engine combination, with crankshaft selection determining the required main bearing setup.

Key Features

• Designed for Gen 5 LT1, LT4, and L86 engine combinations
• 376 C.I.D. displacement configuration
• Available with GM or aftermarket crankshaft options
• Uses aftermarket connecting rods with Clevite connecting rod bearings
• Bearing selection must match the selected crankshaft
• Rotating assembly is supplied without balancing

Important Notes

• GM crankshafts require GM main bearings due to the different journal chamfer. Narrowed aftermarket main bearings will not work with GM crankshafts.
• Clevite connecting rod bearings are used with the aftermarket connecting rods.
• Clevite does not currently offer a Gen 5 LT1-specific main bearing set.
• The Clevite LS main bearing set can be used but requires minor block modification at the center thrust bearing.
• Verify that your machine shop can properly perform the required block modification when using Clevite LS main bearings.

Note: This rotating assembly is not balanced. Be sure to select the correct main bearings for your chosen crankshaft. Product image is representative; actual components may vary based on selected options.
