Re: 307 ?

Yes, a 307 and 327 crank are the same. (all 307 are large journal, while 327 is small journal except 1968 and heavy truck) The internal balance is a bit different, but if you have it balanced it will be fine. Kinda the same thing with a 305 and a 350. Same stroke, but mixed results if you don't rebalance the assembly.
