First of VIN is V8, does this indicate V8 engine?

If I remember right about the AB numbers, 30 is a 273 2 barrel, 31 is a 273 Commando, and 32 is a 273 Formulas S with Commando motor.

In 64 30 under AB is 273 2 barrel. In 1965 30 under AB is 273 2 barrel and 31 is 4 barrel. In 66 31 is 273 2 barrel and 32 4 barrel.
