LS6 Intake

Lightly tap that casting date with a metal object when you see it..

This intake has been sitting for years and wasn't even cleaned up after removal from the engine. I doubt very much that there was anything done to the intake. Being a tool and die maker, I'm not so easily fooled. Not impossible though. I've seen pictures of numbers and such made up from epoxy and filings for cast iron intakes. Even a magnet wouldn't help once the intake was painted.
