Which pan is this?

[Brian Monticello]

I bought this thinking it was the extra capacity SHP oil pan for use with mechanical lifters and now know it isn't. Anyone know the model year(s) and engines it was used on? I've searched the archives and the subject is confusing.

Here's another pic:

It looks okay. What is wrong with it?

Joe,
There is nothing wrong with it. It's just the wrong one - looking for the '65 SHP pan with the trap door baffle. The deep portion is about 3/4 the length of the pan while the one I habe now is about 1/2.

It's a 3820000, used on 63-5 Non-solid

lifter motors and a number of motors after that up to about 1972 - 4 quarts plus 1 in the oil filter

It may be the GM #3820000 pan that Loren mentioned. Or, it may be the GM #360866 SERVICE replacemement for the aformentioned pan. Without a doubt, it is one or the other. The GM #3820000 was used for most 63-74 Corvette small block applications except 63-65 with SHP engines, early 1970 LT-1, and 70-72 ZR-1. This pan was not used for any other application besides Corvette.

The GM #360866 is a nearly identical pan released in about 1976 to replace the GM #3820000. The only difference between the 2 pans is the radius of the front oil pan seal surface. To check this, place a straight edge across the front oil pan rails immediately above the front oil pan seal radius. Measure from the center of the radius to the bottom of the straight edge. If the measurement is 1-1/4", then the pan is the 3820000; if the measurement is 1-3/8", then the pan is the 360866. It's as simple as that.

Joe,
I checked the archives again and found that you posted something similar and probably meant 2-1/4" and 2-3/8". Anyway, i got lucky and have a 3820000 pan. Anyone want to trade for a 3820001?

Thanks for the information.

Yes, I was too hasty in preparing my response; obviously, it should have been 2-1/4" and 2-3/8". That's what happens when I'm trying to get out of the house quickly. Haste makes waste.
