I was given a set of crank pulleys that were said to be BBC with power steering and short water pump, would someone with a parts cd or book verify the application for me please. 375232BB, and 3744043BA. Thanks in advance. Jason.

3774043 I show listed for 66-67 Chevelle w/A.I.R. (396), (exc. El Camino, C.A.C.) and 68 Chevy (396). Pulley (double 6 5/8" O.D. stamped 3774043)

Don't find the other number...yet. Dinner time so I have to quit searching for a bit.

My GM parts book shows the 3751232 to fit:

64 Chevy, Chevelle w/P/S, (327) (exc. Air Cond.)
64-68 Chevy, Chevelle, Camaro w/P/S (327)
65-68 Pass. w/P/S (327) (exc. Sp. H/Per.)
...with note PULLEY, front (stamped 3751232)

Neither pulley is listed for a 327 Sp. H/Per. (L79) and one pulley is listed for a small block and one for a big block. Not to say the pulleys wouldn't physically fit or work together, but I don't think they're for a L79 as the eBay seller claimed.
