1969
1996
i called the Chevy dealership and they told me the year
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
The back of the block will have a series of letters and numbers cast into it. That is what determines the date.
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.
Depending on what the engine was used for, most likely dish top pistons. But flat tops ARE possible.
1969 to 1979 I've seen those blocks up to the mid-80's.
350 and a 327
what year is my 350 chevy engine K1201KRH
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
