Is this the 359942 pan?

[Steven H.]

This is on Ebay, and I need to know if it's the 359942 6 quart correct pan for the 69 L46.

Seller only has it listed as for 327 and G281.

GM shows 359942 for 63-65 327 SP HP and 697-72 HP.

All others show to use 360866 5 qt.

This pan is NOT a GM #359942 or, even, a GM #3820001 which was the original pan used for 63-72 "6 quart" small block applications. This pan is either a GM #360866 or a GM #3820000, the original pan used for 63-74 "5 quart" applications. The only difference between the pans in each pair of part numbers is the radius of the front oil pan seal surface and I can't tell which this is from the photos.

Also, 1969 L-46 DID NOT use a "6 quart" pan; it used the "5 quart" pan. So, even though the seller has, apparently, mis-identified this pan as to part number, it is the correct configuration for a 1969 L-46, save, possibly, for the front oil pan seal radius which is extremely difficult to discern when mounted on the engine.

You confused me just a bit, please help straighten me out.

If we leave out the original numbers to get this straight:

My GM 1983 catalog shows 360866 as 5 qt base motors for 63-74.

And 359942 for 63-72 HP apps including L46.

My confusion from your post is to why you say L46 only used a 5qt and or is the 359942 not a 6 qt?

I've read about the front seal issue before your post; but figure I should get this qt issue solved first, then move to the seal issue.

This one on Ebay is listed as NOS 360866 (3820000); it looks near the same as the first rusted to my untrained eye.

Re: Is this the 359942 pan?

I'm with Joe, Only mechanical lifter engines used the 6-quart pan after '65, so the l046 would be a 5-quart pan 3820000 or the 360866

Please study this 1983 dated GM Corvette catalog and tell me why you contradict it?

I have no issue with the 327's; but why would you say no on the L46? There were only two 350's in 60, ZQ3 and L46. The only thing I could see is that you are suggesting the catalog is incorrect and should have read 70-72 W SP HP and meaning only the LT1?

You're going to find a lot of confussion in the parts catalog in regard to base/ HP/ SHP for 69 and 70. SHP does not refer to the L-46

Your ebay pic looks correct internally. As said the difference for you would be the need for the thicker front gasket IF that is a later pan. BTW the 492 pan would have a hinged trap door to the baffle

Since the LT1 was slated for 69, the catalog lists SHP,(LT1), for 69 in the SB. That 69-71 SP/H/PER reference for the 942 pan is for the LT1. There wasn't a "w/ SP H/PER " in 1969. The 360866 would be correct for you.

That is about what I was starting to suspect.

Are the other two involved in agreement?

Re: Is this the 359942 pan?

Yes, the '83 catalog is difficult to interpret, if not incorrect, I referenced a '71 parts book to provide my answer.

Re: Is this the 359942 pan?

Unfortunately; the 1983 was the only one I saved when we dumped printed catalogs 20 years ago.

Excellent, case closed and very much thanks for the help!

Now the only question is whether to get the rusted one for $75 or the NOS for $400.

Re: Is this the 359942 pan?

Trust me I've been through this with my 70 L-46 for years. If you want to check this go look at a carb for 69 SB in the catalog(3.725). you'll find the same holley carb as listed for the 70.(LT1).

[Steven H.]

Re: Is this the 359942 pan?

To make matters worse; the line used 70 parts on late produced 69's.

This has to be one serious nightmare to judge.

Re: Is this the 359942 pan?

Steve, the "rusty" one really doesn't look too bad if you have a bead-blast cabinet. I'd trade a half-hour for $325 anytime.

[Dennis D.]

Re: Is this the 359942 pan?

One last thing. Search the archives. I thought there was a thread that discussed the vertical indent differences from the early to later pan.

[Steven H.]

Re: Is this the 359942 pan?

I got the rusted one.

Cheap enough I'll chech it out and deal with the seal and pick up part as needed.

Oh, what about the main cap mounted baffle, was that LT1 only as well and nothing was used on the 69 L46?

Corvette Central has all the cap parts; I just need to know if my app used it.
