I am in the process of swapping a 250 6 into 58 biscayne that has a very tired 235, I have read that the flywheel and bell housing will need to be replaced with one from a 283/ 327. But i have not been able to confirm this reliably. you folks were such a big help when i was building the 58 apache that you were my first thought to get the information with any degree of reliability.
any other words of wisdom on this subject would be appreciated also.
thanks Mike Bourg
