HI,I` M NEW TO THIS, LOOKING TO BUY A 455 BB OFF THIS GUY &WAS WONDERING IF ANY ONE KNOWS ANYTING ABOUT REMAN LONG BLOCKS&IF IT WILL FIT IN MY 1972 CUTLASS.THANKS FOR THE HELP

 

A 455 will fit in your 72 Cutlass. You just need the right engine mounts. I believe there were different motor mounts for big blocks and small blocks. By remanufactured do you mean that it has already been rebuilt by the current owner?

 

The big and small blocks had different mounts but they are interchangeable as a set. Just retain the existing frame mounts, use the 350 motor mounts, and bolt them right to the 455. Once again, prior to 1969, both big and small blocks used EXACTLY the same mounts.
