Description
GM Performance Parts 10134400 400 Aluminum Bare Block

Less weight and the same great horsepower are the benefits of a GM Performance Parts Aluminum Race Block. GM Performance Parts Aluminum Race Blocks provide the same competition-level strength and reliability of our cast-iron Race Blocks, but their lighter weight improves chassis dynamics. The super-tough A-356 aluminum competition blocks are CNC-machined to +/- 0.001-inch tolerances. GM Performance Parts Aluminum Race Blocks are ideal for road racing applications or high horsepower turbocharged engines.*
