Thats not possible to put a large journal 350 or 327 crank into a small journal 265-327 block unless you have the block mains machined (line bored) to fit the large journal crank. unless you ment you can buy (from where?) a bearing spacer set for putting a small journal 283 crank into a large journal 327 or 350 block making a 302? otherwise the only bearing spacers we've seen is for putting a 350 or large journal 327 crank into a 400 block since a 400 has larger main journals than a 350 or large journal 327. But the small journal engines were the 265-283-302-327 1967 and older when the 350 came out in 1968 chevrolet switched to the large main journals 307 and up. 1965 an older 265-283-327-348-409 had stock forged steel cranks and its rare to see a stock motor with a forged crank after 1965 when they switched to using stock cast iron cranks.
But otherwise its what i talked about at the machine shop with the guys and i thought i'd share it with you all.
