This start solenoid valve heat shield is for 1965-1997 small pieces , 262 ci, 283 ci, 302 ci, 305 ci, 307 ci, 327 ci, 350 ci, 383 ci and 400 ci. and 1965-1976 Big Blocks, 396 ci, 402 ci, 427 ci, 454 ci, 502 ci and 572 ci. engine. Installing this shroud protects the starter and solenoids from heat generated by the exhaust manifold or header, making the starter assembly easier to start and longer life. 0.032 aluminum shrouds are packaged flush with instructions. This design reduces any disturbance to surrounding components while maintaining an air gap around the starter and solenoid to reduce operating temperatures.
