    Can you ID this SB Oil Pan

    Not sure if this is a run of the mill small block oil pan or something to a specific car. Any ideas?

    Thanks,
    Dave

      Drain plug in the wrong place for anything C1-C3.

        1975-79 Corvettes used oil pans with a side drain. However, this pan is definitely not one of them.

          This is not a GM oil pan. Based on its overall configuration I would say it's an aftermarket pan of the type which would be called a "one size fits all" sort of pan. It would work for many 1963-79 applications, including full size passenger cars, Camaros, and Corvettes. Likely others, too. It is similar in configuration to the 1975-79 Corvette pans but would never be mistaken for an original by anyone in-the-know. With change of the oil pump pick-up it could be used for 1963-74 Corvette small blocks but would not resemble the original pans.

              The pan in the foreground is one of several GM pans. These are as follows:

              GM #3854788
              GM #3900416
              GM #3912396
              GM #3937914
              GM #3961399
              GM #3974252
              GM #360010
              GM #465221

              GM #3916369
              GM #3927134
              GM #3961398
              GM #3974251
              GM #360009
              GM #465220
              GM #360450

              These oil pans were used for many Chevrolet applications. If you could post a photo of the underside of the pan and also measure the front oil seal radius, I could narrow it down.

              As far as Corvettes go as well other applications, the GM # 360010 was used for 1975-76 Corvette L-48. The GM #465221 was used for 1977-79 Corvette with L-82. The GM #360009 was used for 1975-76 Corvettes with L-48. The GM #465220 was used for 1977-79 L-82.

              As far as external configuration goes all of the above referenced pans are virtually identical. The differences primarily involve internal baffling and front oil seal radius.

                    AFAIK I believe the pan in the foreground is 465221 according to my Chevy Truck Parts Book. Larry

                      That's a possibility. It depends on a lot of things, though. What application it came off of would count for a lot. There's no way to say it is a 465221 that was originally installed on a truck unless you know that's what it was originally installed on.

                        Thanks Joe; It did indeed come off a 1977 Chevy Sport P/U LS9. I had to buy another one since time did not
                        permit to repaint this one. The Corporate Blue Powder Paint shade was a little different from the original
                        tint. So to match up everything I had to go this route. Just curious did pan#360009(L-82) look a more like my
                        GM #360866 ("5 quart") Corvette Service Replacement Pan in the picture?? Larry

                          No. The GM #360866 has the same external configuration as the 1963-74 GM #3820000. The only difference is the front oil seal radius. Both of these are Corvette-only oil pans and were never used for any other Chevrolet application.

                          The GM #360009 has, essentially, the same external configuration as the GM #465221 or 465220. I don't know exactly what the configuration difference is, if any, between the 360009/360010 and the 465221/465220. All of these pans were used for many 1975+ Chevrolet applications, including 1975-79 Corvette.

                            Dave,
                            Your aftermarket oil pan looks somewhat a 1969 Chevrolet-Chevelle-Camaro oil pan (painted red in my photo) and a 1970-1974 Chevrolet-Chevelle-Camaro oil pan (painted gray). The two oil pans in my photo are almost identical but not quite.

                              As I see you have it marked, the pan on the left is likely a GM #3961399. However, depending upon internal configuration, it could also be a GM #3961398. The latter is much rarer, though, as it was only used for 1969 Z-28. If this pan came off a very early 1969, it could be either a GM #3912396 or GM #3937914 if a non Z-28 or a GM #3927134 if a Z-28. None of these pans were ever originally used on a Corvette.

                              The pan on the right is a GM #3974252 or GM #3974251 depending on internal configuration.

                              The pan pictured in the original post of this thread is definitely a "one-size-fits-all" aftermarket pan designed to work with a wide range of Chevrolet applications. It was even cataloged for 1963-74 Corvette small block though it does not even resemble the original pans for these applications. Note the "squared off" configuration of the front of this pan. That's a dead-giveaway that it's non-GM. Note also the difference in configuration at the oil drain.
