1969
1996
casting number 3970010 is a 350 block from 1969 - 1979 but in 1969 302 and 327 have the same casting # and im not to sure about the other #
a 350 or 327 that is the question. A 350 or a 327
i called the Chevy dealership and they told me the year
The back of the block will have a series of letters and numbers cast into it. That is what determines the date.
1969 to 1979 I've seen those blocks up to the mid-80's.
Look again, could it be 3970010? If so it came out of a 1969-79 car, truck or Vette
That engine could be anywhere from a 1969 to 1972 350. Some of them were 4-bolt mains and some were just a 2-bolt main engine.
That should be a 4 bolt main 350
What Chevy engine has the casting number 3970011?
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
