Checked my carb number and its 17066605 with a 1435 under it. I would put a pic up but it's too difficult to do with an iPad. Would this be a service replacement? It seems to have the right base for a turbo motor with all the right ports. No other letters or numbers. And the stamping is clear, numbers are not 8's. Doesn't match a 1980 Turbo 301 Trans am. The car is a First week of December 1979 build date. Maybe a turbo Monty Carlo carb?
