Gm 3970010 the model?
a 350 or 327 that is the question. A 350 or a 327
you need the date code on the side of the block it will be a series of numbers and letters first its the month, then day, then year
it is a 1969-1979 motor it was used in cars, trucks, and vettes
those numbers are the date that it was built k=month .... 24=day ..... 5=year November 24 1965 or 1975
No. That number was used for 302's, 327's, and 350's. (4" bore)
A81 should be January 8, '71,'81,'91.
