I recently puchased a 1970 El Camino and beleive the motor has been replaced. I am trying to determine what engine I have to include the year and what it came out of. On the left front of block I found 2 casting numbers. One is V0928TBM and under that is 0901l2484. The driver side rear shows 3970010. Can anyone help me identify this block and what yeat and model it came out of?
