If you spend a substantial amount of money having the crank turned down from a large journal to a small journal sbc, If you can get a machine shop that would even do this!! After a substantial amount of material is removed, the hardening of the metal tends to be erased, a more accurate assessment would be that its got a small journal 327 crank in it, I'd have to do some research, but I believe this makes a 301 cid engine.

Adding a small journal 327 crank to the 283 was common, however using the 283 crank in the 327 block is how the DZ302 was built. SCCA high revving race motor back in the late 60's.

In all probability your 283 block is a large journal crank block ( 2.45 main journal size), chevy made them both ways. Only the early 283's had the small journal crank thru about 1967 (2.30 journal size). After that 283 blocks were all large journal cranks ( 2.45 main journal size).
Now with that said installing a 350 crank into a 283 does in fact stroke the engine size. Going from a 3.00 stroke on the 283 to a 350 crank at 3.48 gives you more cubic inches, but is this a good way to go? Me I will take the high winding 3.00 stroke every time.Protected people will never know the intensity life can be lived at. To do that you have to understand completly the meaning of the word "DUCK"

Pretty sure it was meant as 1967 was the last year for the 283. 1968 brought the 307.
