Quote: I know it was a 440 center but I think the blokc and the bowl are from the 340 carb. That being said what issues could that cause? Again, I have had no issues with the way it actually runs, if it hadn't been for the surge I would not have started tweaking it at all. Granted it doesn't run like a EFI vehicle but I don't expect it to, most of my cars are carberated so I am well aware of the differences.
The metering blocks need to match the carb. # Mismatching them can drive you absolutely nuts Take the time to look very closely at all the holes and passages in the main body and the metering block, then remove the jets and see if yours has the emulusion tubes in it like the 340 carb. metering blocks have
