Did some 300hp 64 Corvetts come with the breather tube that runs around and down the side of the bell housing? My early 64(#4013) has this configuration. also, the underside of the air filter does not have the fitting to connect to a breather. It looks like the 63.

Re: 64 Breather tube
My early 64, built approx 1400 units before your 64, has the fully closed system. Looks like Bubba's been sneaking around while you're at work.Comment

Re: 64 Breather tube
63 and 64 engines have completely different PCV design architectures. The AIMs and shop manuals have the details on how they are configured.
