Can you ID this SB Oil Pan

[David S.]

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

Thanks,
Dave

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.

Here is a comparison of some of my "ManCave" Oil Pan Decorations> Background pan is
GM #360866 ("5 quart") Corvette Service Replacement Pan. Foreground is a stock Chevy 1977
Pickup LS9 350 CI Engine. (Was Corporate Blue Before we Powder Painted it Chevy Orange)

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.

Corrections to my above post (would rather have edited but editing has lapsed for that post):

The GM #360009 was used for 1975-76 L-82.

The GM #465221 was used for 1977-79 L-48

Thanks guys. Always worth checking.

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.

Re: Can you ID this SB Oil Pan

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.

Re: Can you ID this SB Oil Pan

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.
