I hope that you are planning staying out of the gas pedal. 327s are short stroke engines and rev up real fast. You have 4 u-joints and a transfer case designed to handle a low RPM 125 HP inline six 235.
I am not trying to dissuade you from doing your swap, I just know a guy with a '57 NAPCO who went with a 300 hp 350 crate motor and could not keep the bearings in the transfer case or was blowing out U-joints.
Granted, he could not keep his foot out of the gas.
