OK so I pulled the engine code (front passenger head boss) and mini VIN from under it. I cant find ANYTHING about the TDS suffix. I know its a 1978 something (350 I would assume) and was made on July 7 at Flint Mi. Was wanting to know the rest of it as what size and what TDS is and isnt the C supposed to be T for truck? Maybe Im wrong.
