I have a 57 block that ends with the letter C that has been magged and cleaned, Also have a brand new small journal 3 inch stroke crank.

57 blocks had no side motor mounts.

57 blocks had no side motor mounts.

Side mounts did not show up until 1958.

The block I run in mine is a 3720991(1956 number) but it has the neoprene rear main seal so it must have been a service replacement unit. No side mounts.

The '57 265 is a 3731548 and the number on the passenger side(on the pad in front of the head) can be either a "C,CD or CE". Mine is a "CD" which I believe meant it came with a 3 speed overdrive manual transmission. The car it came out was a 2 door wagon.
I think "CE" meant heavy duty clutch.

I call it a "Poor Man's" Bow Tie block.

Crank is part #3735236.

None of the 265's I own have side mounts.
