This all can be for the Monte but not for it, '78, '81 Pontiac & '79 Olds CSM's. Got them for reference reasons & found out they have more usable info than the Chevy ones. Then I got a fair deal on a used GM Performance intake just because. I could just swap out the Edelbrock or just add it to the '68 & about '76 iron intakes on the shelf.
