Re: 307 Chevy motor

307 uses the 327 crank with a 3.25 stroke
307 has a 3.875 bore
350 has a 4.00 bore is
230 has same stroke and bore as 307, so pistons should fit-check part numbers
250 bore is 3.915 not 4.00
you could bore out the 307 to 4.00 but need thick cylinder walls (different 307's have diiferent thickness) so you need a sonic check
