Im running a 4bbl on my 1990 LO5 with no A/C or A.I.R. but im running the same multiple belt style as your's the numbers i saw on my belt 100 / CR the belt might be about 12-15" long. But im pretty sure that any part store should be able to help there are two setups: Power steering to crank to water pump thats what im running and the second one Power steering to crank to water pump to A/C unless some how the A.I.R (smog) pump is included but the store should be able to help.

Run a long piece if twine of string around the pulleys in question. Measure the length where it meets. That'll tell you what length you need.
