Thanks for the help guys
also a rebuild kit for the carb. I should be able to take my carb to O'reilly's or Kragens and give them the number and get a kit right? Are there better rebuild kits out there??? Manufacturer?

 

66-33867 LAN: '66 Cutlass Convertible built in Lansing

612: is this after that "LAN"? If so, the body sequence. *Very* early build
088-C: interior code, have to look further, think it is black strato bench
C-1: Provincial White paint, black(?) top
W - tinted windshield
S - power trunk
2X - column shift automatic
T - power rear antenna
4F - remote driver door mirror
C - Chrome side window sill molding
5Y - deluxe seat belts

 

Sorry the 612 is supposed to be C12 it had a white vinyl top and maroon ish reddish interior. it does have a tilt column and a 2 spd glide also power antenna power top and I think it had a remote mirror but no power trunk. Im still having problems decoding the motor..... Thanks

 

Okay, start with the number on the block behind the water pump on the "shelf" in front of the intake manifold. What is it?
