What size motor you got motor number c302-10114182?

The first part of the number you have there is the date code. C 30 2 translates to March 30, 1992. This is a 454 Generation V Big Block Chevrolet. You should find a VIN number on the pad by the head on the passenger side on the front of the motor. You can use that to help decode where the engine came from. Hope this helps. Tony Shields
