Hy olezippi and guys, I'm sure most of you realize that the Chevy V8 302, 327 and 350 are all four inch bore blocks. 302 has a three inch stroke, same as the 283, 327 uses a three and one quarter inch stroke, same as the 307, 350 has a three and a half inch stroke. All of these engines were available in small and large bearing versions. In the good old days we used to bore 283 blocks out to four inch and we would create 301 cubic inch engines.
