Thanks joe!

More specifically:
1971 Full size, Chevelle, or Camaro 402/300 with Turbo 400
1972 Full size 402/210 with Turbo 400, 1972 Chevelle, Monte Carlo, Camaro 402/240 with Turbo 400
What's the partial VIN?

you didn't state if big block or small block
-
I think the (402) would be a big block which is just the late 396 bored out that they continued to advertise and call the (396). The smallblock would be a real (400).
-
small block as a CLB code and big block as a CLB code

Learn something new every day. I always thought the 402 replaced the 396.

I always thought the 402 replaced the 396.
It did. There weren't any 369 engines installed in any production car or truck after mid August, 1969. They were all 402 engines. A lot of sites post incorrect information and even Chevrolet literature continued to call it the 396, the 402 AND the 400!
Per the September/October, 1969 Chevrolet Service News and the NOVEMBER 16th, 1969 PRODUCT SERVICE BULLETIN (http://www.camaros.org/images/ref/PSB_69-00-32.jpg), big blocks with the 1970 and later 3 digit engine codes are actually 402 (or 400, depending on what document you look at) cubic inch engines. This included the late 1969 Camaro big blocks. However, some Chevrolet advertising and sales literature still referred to the 402 (or again, the 400) engine as the 396. Not sure when all that ended, but it sounds like they had a heck of an argument about "size" in the marketing department!!

The 396 turning into a 402 but still 'called' a 396 was a MARKETING issue... They had built up the customer base/market for an SS396 and I guess they didn't want to confuse us... :) Does anyone know WHY they changed the size (Bore I think?)... Was my 383 RR beating too many of those SS396's?? :)
-
I think they changed it because the 396 had a bore of 4.094, which was kind of a strange bore. The 402 bore was 4.125, which was more in line with their tooling.

-
That makes sense Ed.. Thanks!
-
400 small block is also 4.125 bore.
-
I think the change was for emissions - over 400 ci had different requirements. But I can't find anything to back it up....
