Show original supplier description
The American Powertrain MD-401-1211 is a Quick Draw, HD aluminum bellhousing engineered for the Tremec TR4050 transmission. Constructed from durable A356 aluminum, this bellhousing offers a cost-effective solution when a steel housing is not required. It is specifically designed to bolt Chevy Small Block, Big Block, LS, and BOP V8 engines to the TR4050 transmission pattern. The bellhousing is engineered to accommodate a factory GM flywheel and a 1.125-inch (1 1/8) 10-spline clutch, ensuring compatibility with common clutch setups. The package includes all necessary hardware and installation instructions for a straightforward integration into your drivetrain. This aluminum bellhousing is suitable for street cruising applications with engines producing under 500hp. For racing applications or engines exceeding 500hp, a steel bellhousing is recommended for enhanced safety. The bell housing features a hydraulic clutch release type.
