This is incorrect information. the 307 has a 3.875 (3 7/8") bore, while the 350 has a 4.000 (4") bore.. Basically, the 307 is a stroked 283 with the same stroke as 327.. A 350 is a stroked 327 using a 3.47 stroke crank. Meaning a late 327 and 350 are the same block. The short lived 302 had a 4" bore and the same stroke as a 283... The only thing in common with ALL these engines was the rod length -- 5.7".
