1968 L79 intake manifold part number
 

I'm looking for a '68 L79 (327/350hp) intake manifold part number. I'm finding different numbers online and need some knowledgeable assurance.

Welcome to the forum. I'll check my old 1973 Parts Catalog.

Bear in mind that the number I'm giving you is from a 1974 Chevrolet Corvette parts catalog. This is for a '68 327 Rochester - 3931575. There is a note that says it might be necessary to plug the water temperature switch hole with a 1/2"-14 pipe plug.

That's the only part number in the catalog for a '68 327. While that number may have changed over the years, a Chevy parts guy can pull it up and can tell you if there is a new number for it. That's not unusual. Hope this helps.
