T-Bird, the engine might run, but I doubt that it would run well. The issue would be where the 36mm manifold faces up against the 32mm intake port. There would be a 2mm step around the circumfrence of the port with the face of the step facing back up to the carb. The result would be an accoustic "echo" back up the intake manifold which would be bound to mess up the carb. It would basically be a "worst case" porting scenario. I could only imagine that this set-up would have an awful reversion problem.

BTW - having this set-up on the exhaust ports on the other hand can often be a good thing. In this case the step from the larger diameter exhaust pipe to the smaller diameter exhaust port can often help when cams have a lot of overlap. The step reduces the tendency of the cylinder sucking the exhaust back during the period of valve overlap.
