Discontinued - LS6 5.7L Base with Camaro/Firebird oil pan kit

Want to put LS6 power in your Corvette, Camaro or Firebird racecar? This long block assembly is the ticket. It comes with a Corvette oil pan installed, but includes a Camaro/Firebird oil pan and all the necessary components to fit it to the LS6 engine. The engine does not come with the intake manifold, throttle body, balancer, flexplate, exhaust manifolds or electronics.

Customize it to your tastes—knowing that it has the heart of a 405 hp titan. Includes hollow-stem valves, and the powerful reciprocating parts found on the LS6.
