1970 L-78 Engine Code & Car Vin # Question

[Rowdy Rat]

The "W" is actually GM's Willow Run plant which is located in Michigan. While many 1969 Norwood Camaros used the area near the oil filter to stamp the VIN derivative, I can tell you (with reasonable certainty) that Willow Run used the pad in front of the right cylinder head exclusively. I have not seen or heard of anything different on a Nova.

I know that the Willow Run plant built other cars besides Novas (Corvairs come to mind, but that would have ended in 1969), but I wouldn't rule out an error in the Colvin book either. I'm with Joe - I never heard of an L-78 Monte Carlo, but I guess stranger things have been built.
