engine indentification

I have a motor out of a 1970 chevy truck: however, it is not the orginal and I am trying to indentify the motor. The block cast number is 3970010, piston # is 6271096, front of block is V0803 CUB, the head # is 333882.The motor appears to have been casted in 1976. I beleive the motor came out of a car and is a 1976 nodel.
