I’m trying to sort the mystery out. So I went out to the truck to check the numbers. I mic’d the bores. Here’s what I have.
Bore of intake manifold-1 11/16”
Bore of the carb base-1 11/16”
Intake Manifold cast numbers-3835580 GM on the left side, 24 on the right side.
Bolt centers-2 15/16” center to center
Carb lower side of base-7005608 (faded)
Under carb base-15018
Upper side of carb base-6
Engine-0329620F54X
Head-3835913 GM1
I am very appreciative for all the help sorting this out. I will continue on this quest for a running AD Chevy. All advice is welcome.
