Greetings everyone! I am just joining the Gbody family with my 84' Monte Carlo SS (see pictures below). I have been trying to figure out how to decode the vin number 1Z37-LES-111812 and the engine code is ES-111812. I know my car came with the 350ci, 4 barrel qjet carb that is inside of it but I can't figure out the engine specs. I also know that 1Z37 corresponds to 75 and newer corvettes. Can anyone help me out?!?
