Re: 1985 TBI Canadian Plainsman
The VIN plate is attached with rosette style rivets, which normally is a good sign (because they are not readily available).
VIN decodes as follows:
1 - Country of origin - USA (make sense, since all Suburbans were built in Flint MI)
G - General Motors
8 - Seems like this should be a "C" for Chevrolet
G - Brake system 8100 - 9000
C - series, 2wd
2 - 3/4 ton
6 - Suburban
W - engine code (I didn't check)
4 - check digit (randomly calculated value)
F - model year, 1985
F - Assembly plant - Flint MI
numerical portion of VIN corresponds to build sequence number
The sticker has been messed with; pulled off and replaced. You can tell because the "typed" notes should be legible, and yes it should show the same VIN as above.
To answer your earlier question: no TBIs on fullsize trucks in '85. We've had this discussion before and I can answer with confidence, because I 've had conversation with the GM Powertrain guys who did the calibrations for these TBI engines. They have said no TBIs until 1987 model year.
