Thread: L31 RPO Code???

  1. #1

    Default L31 RPO Code???

    so, im decoding my RPO codes, and so far all is well...except when i got to the engine code which is "L31." this is what it says:

    L31 : 409 CID V8 400HP (SPECIAL HIGH PERFORMANCE-SOLID LIFTER CAM)

    i thought that it had a Vortec 350? can anyone clear this up for me please, thanks!
