7090 454 BBC GM TKO/TKX COMPLETE TRANSMISSION INSTALLATION KIT

This Holley Complete Transmission Installation Kit, MPN 319-502, provides all necessary components to install a TKX or TKO manual transmission onto a 1970-1990 Chevrolet vehicle equipped with a 454 big-block engine. The kit features a lightweight cast aluminum bellhousing with a stamped steel dust cover for a factory-like fit, a 36 lb, 168-tooth billet steel externally balanced flywheel for strength and reduced weight, and a roller-style pilot bearing to enhance shifting performance and reduce parasitic drag and transmission wear. It includes a 26-spline, 11-inch organic clutch disc with a heavy-duty hub spring assembly, capable of handling up to 500 horsepower, and an adjustable hydraulic release bearing for easier installation and reduced pedal effort. This comprehensive kit also provides all required hardware, making it a complete solution for driveline conversions. It is compatible with both OE (original equipment) and MSD High Torque starters.
