Paging Mr. Devilbiss...


FYI, Olds didn't use engine codes in the VIN until the 1972 model year. There is no such thing as a 1970 or 71 "U-code".

Thank you Joe. I have read people posting X code, V code, U code and wondered.

Brandon, shoot me some pics and info if you don't mind - I have a few U Code cars tucked away on my hard drives with the V Codes and SXes. I get inquiries about them from time to time. Thanks.

I've had two U code 72's and they are a desirable engine size. My first one sold for 38000.00 but had documentation all the way back to first owner. I have one now and people like that it has the big block. No value yet unless you've advertised it. Good luck with it.

I am of the understanding that part of the 72 442 package's redefinition was that the engine size became independent of the model/package of the car.

Thus a 72 normal Cutlass could be ordered with a 455, and I believe this was not the case in previous years, as it was tied to the 442 model only.

That's correct about the 1972s, but the L-33 455 2 barrel was available in the Cutlass, Cutlass Supreme (with or without the Y-79 SX package) and Vista Cruisers in 1970 as well.

And for completeness, in 1971, the L32 455 4bbl motor was available in the Supreme (with Y79 SX package) and the Vista, but not in lesser Cutlii that year.

Were optional rear gear ratios shown on the window sticker in 72? If yes does anyone have an example of this that they can post?

They were an extra cost option, so yeah that would be on the window sticker.

Because the first one is the TH400 as used behind big blocks. The second one is really the TH375 used behind small blocks in the Vista and D88. Both were coded RPO M40.
