1970 L-78 Engine Code & Car Vin # Question

[JoeC]

ElCamino - Thanks for your input. I believe you are correct that it is a Nova L78. I disagree that the digit 2 is "just" a sequence and does not indicate any model information. The first digit of the sequence number can be different for different models. For example the 1970 Nova VIN sequence begins 100001 the 1970 Camaro begins 500001 and 1970 Monte Carlo built in Arlington begins 200001. That made the "2" digit look odd. The vin W274985 is the 174985 Nova built but the engine date code is February. I thought that also looked odd because of such a high VIN number until I looked up the total production units of 1970 Nova's. Willow Run built over 307000 Novas. That's a lot of Novas. I guess this car being the 174985 unit built could have had a February engine date since it would have been assembled during a little over half the production year.
