A sure way to identify a 55 (only) block is that the road draft tube runs right down THROUGH the block while 56 and up road draft tubes are held down to a hole at the rear of the block with a long 1/4-20 bolt. If either block you have has an oil filter mount on the lower left corner it is NOT a 55 265. I think I have access to a 55 engine if the lady hasn't disposed of it yet; she's cleaning out all her deceased husbands toys. As others have said, ANY swb 55-57 frame is correct and 58,59 with a little tweaking. Here is a 57 we did with a generic frame that wins just about every show it's been entered in even though it gets a magnifying glass going over by so called "expert" judges. The last picture shows original frame that was torn, butchered, and rusty (just front part).
