You have a 77-80 block, head, and crankshaft probably NOT 76. I can't help with the cam number.
Check your block vin stamping. The first digit will be a 3 it indicates oldsmobile.I believe the second digit is the year. the 3rd will be a letter which is the assembly plant, the remaining numbers will be the serial number of the vehicle in which the engine came from.
