I think the carb for the 292 if correct should have the same bore as the manifold at 1 5/8". 250's used a smaller bore carb at 1 9/16 on the same manifold.

We had a 292 in a 67 1 ton and I don't remember any carb problems. It burned lots of gas but then again it was a work truck with a heavy dump box. Lot's of torque in those engines.
