will any SB fuel pump work on a 65 273

Change your fuel pump and always check the pressures. A buddy had carb bleed oner issues with 2 cars, same pump transferred to a 440.
We checked the pressure and it was at 6 1/2#. He went down to the local parts tore and picked up another pump and installed it. No! it was 8#. He took it back and got one for a 383 this time. (less pressure we thought) Well, it was at 10#. He found a regulator in a parts tote and turned it down to 5#. Within 30 seconds the thing started idling smoother and cleaner. Sorry to ramble on. It's a story that needed to be told. LOL
