14010207 is probably not not a Corvette motor. It's a 350 - could be 2 or 4 bolt (as you already know) and was used in all passenger, i.e., Camaro, Malibu, Impala, etc as well as light duty trucks. 190hp in the 2 bolt configuration and 230hp in the 4 bolt. It would have been a late production for 1980. If you can you get the number off the front pad (passenger side) as that could help us decipher when exactly it was made..
