I have a PCM/Sea Maxx marine engine that was installed in a 1997 Shamrock. I’m in the process of rebuilding the engine, and I’m trying to determine the correct specs on the cam. The numbers on the end of the cam are 395 WB37 and 317 96R. Can somebody tell me exactly what these numbers mean?

Thanks.
 
likely to refer to GM PN 14097395 - their default marine cam for a 350HP marine application. should be .431/.451" for lift but my notes don't show the rest of the data...I'm sure a quick check in the GM performance catalog will fill in the blanks
