4wd oil pan different than 2wd?

[TimmyG]

Is this a factory oil pan for 4wd 720? I'm not familiar with them. 

[Charlie69]

Yes because of the front diff.

Thanks. That makes sense. I bought the truck with the engine sitting in the bed, so never seen it in the engine bay yet.

Depends. The Z series were bulged on the right and the 1980 with the L20B were bulged on the opposite side...

Should have said it's an 84 with z24

[Charlie69]

It does not matter L or Z as the 2wd and the 4 wd pans for both series engines are different because of the front diff.

If Z24 then it matters that you have the Z series oil pan if 4x4. The picture I posted is for the '80 4x4 which had an L series engine.

 

This looks like the right side of a Z series engine, bulge on the right.

 

This is the front on an L series 4x4 oil pan, bulge on the left.

 

 

2wd pans are all more or less the same for all Z series. The L series is similar but leans about 18 degrees to the right side at the top. See above picture.
