1964 manifold, identified visually and by the date code.

Carbs I can’t say, however the center carb has the inlet on the side where it should be towards the front so likely not a Tri-Power carb.

Pictured below is what a 1964 center carb should look like, the end carbs happen to be 1966 on my 1964 setup.

Thanks for the help. Dick Boneske is putting together a complete 1964 tripower for me, with the correct carbs. I saw this one for sale locally, and contemplated picking it up just to have on hand. The seller wants $1000 though. Not sure what to offer for this one.

I’d offer maybe $600.

If the center carb was correct it’d be worth closer to the asking price.

Ask Dick what he thinks.

The Pontiac race book lists all the intakes, up to 1979
