Default Turbo ID?

Can someone help me identify exactly what these turbos are on my car? I'm not sure they are matched to my engine (427 built by LME), but before I can figure that out, I need to know what these are exactly. These are rearmounts, btw.

Meanwhile, I am trying to find out if the turbos on the car are actually of suitable size for my 427 engine. What I was told by by the place they came from (Turbos Direct), is the following when I asked them directly about the turbos:
Looks like they are T3/T4. 57 trim on the comp side, and stage 3 on the turbine side. Each one is good for about 425-450hp at the crank.
Looking at pics I took of the turbo housings myself, I see the following info stamped on the housings:
  • Turbine (exhaust) housing - A/R .48
  • Compressor housing - A/R .60











Appreciate any advice I can get here.
