GT-750 intake manifold inner diameter?

thought someone might have their carbs off, or have a manifold laying around loose, and be able to stick a set of calipers in them to get an ID measurement - even an OD on the carb inlet that slides into the manifold would work as well - trying to figure out what size plug to get for the intake side, I'm putting together a cylinder lead down tester. exhaust side takes a 2" test plug from a plumbing supply shop or a box store.

TIA

The inside diameter of the intake boot for LMAB models is close to 1.75 inches. You should be able to get an expanding freeze plug at the auto parts store that will work.
