On my 57 bel aire with a 350 crate engine, when I run the car from cold, the dash water temp gage gradually rises to full hot and stays there. Installed separate water temp gage using a different port and it reads normal

Assuming you have the stock electric gauge that came with a 56 the Delco sending unit should read about 555 ohms at 80 degrees and 95 ohms at 200 degrees. You can put an ohm meter on the sending unit with the gauge disconnected from it,run the car from cold to operating temperature and check for about 95 ohms when at operating temperature. If it goes much lower then 95 ohms it is either a bad sender or the wrong one. Keep us posted Good luck.
