I tried to search with no sucess. I am replacing the BB on my surly steamroller with a Phil Wood. I will be using campy record cranks. Which size do I need?

Which model Campy Record crank? Older square taper or the newer Ultra-torque style? If it's an Ultra-torque, you have no choice as to spindle width since it's built into the crank arms and I don't think Phil Wood makes the bearing cups for them.
If it's an older square taper, why not ask Phil Wood? They should certainly know what spindle width you need.

Is this the crank you will be using? It says in the description 111mm track spindle (different from a 111mm road spindle based on what I've read).
BTW, I'm assuming a track crank given the Steamroller's 120mm rear dropout spacing.

Its an older 80s square tapered crank. I Guess asking Phil Wood would make sence although it had not occured to me

You might also have success talking to Campy even though it's an old crank. How the crank sits on the taper (i.e. what spindle gives what chainline) is a property of the crank, not the BB. Sugino was able to give me this info about one of their cranks when I was spec-ing my current good bike.
Phil Wood BBs are less of a sweat, though, as the BB can be moved left and right a bit in the shell. So you could probably wing it.

If it's a track crank, I would suggest trying the 111mm track bottom bracket as is specified for the newer Record track cranks. It would at least give you a starting point. If the chainline is off, you'll know exactly what length you need to make it right after measuring the chainline.
