Six quart oil pan.

[Tom H.]

Can anyone give me the correct dimensions of a six quart corvette small block? Is there any way to recognize one other than dimensions, and did they make six quart pans in more than one configuration. I'm looking at years 69 thru 75. Thanks, Tom

Check out the following eBay completed auctions for numerous pictures of the "6 quart" small block oil pan. Pay no attention to the descriptions, though, as there is much "inaccurate" information presented there:

2439027750
2454813175
2456333593

The "6 quart" oil pan was produced in only 2 very slightly diifferent configurations. These were GM #3820001 which was the PRODUCTION "6 quart" oil pan and GM #359942 which was the SERVICE "6 quart" oil pan available after about 1976. The 2 pans are identical EXCEPT for the front oil pan seal radius. The original pan used the 2-1/4" radius used on all 1955-74 small block oil pans; the SERVICE oil pan used the 2-3/8" front seal radius used for all 1975+ small block oil pans.

During the 69-75 period that you specified the "6 quart" oil pan GM #3820001 was used for only a VERY limited number of applications. These included, possibly, very early 1970 Corvettes with LT-1 and all 70-72 Corvettes with ZR-1 (a total of 53 ZR-1s were produced over this period). So, as far as ORIGINAL PRODUCTION applications for the pan over the 69-75 period, there were VERY few used.

NO other Chevrolet car line used ANY of the 1963 to 1974 Corvette oil pans, so none of them, including but not limited to the "6 quart described, will be found originally installed in any other Chevrolet car.

Joe
Can the newer pan beused on the older motors? If so what do you need to ask for in the way of gaskets?

Re: Six quart oil pan. Joe

Terry - the new pan can be used on any of the engines, the only difference is the gasket radius as Joe describes. For leak free usage the Felpro one piece gasket comes both ways, I don't recall the Felpro part numbers offhand, but Joe will know them....Craig

Yes, the SERVICE pan, GM #359942, is designed to be used on ANY 63-72 Corvette which originally used the 3820001 "6 quart" pan. When using the SERVICE pan, the 75+ gasket kit must be used and this gasket unit was supplied with the SERVICE pan.

The following gasket kits are applicable:

ALL PRODUCTION 1957-74 Corvette small block oil pans, including, but not limited to, the "6 quart" 3820001:

GM #14079400
Fel-Pro 1 piece= OS-34509-T

ALL PRODUCTION 75-79 Corvette oil pans + 1957-74 SERVICE oil pans GM #359937 (57-62), GM #360866 (63-74 "5 quart"), GM #359942 (63-72 "6 quart"):

GM #14079399
Fel-Pro 1 piece= OS-34510-T

If purchasing an aftermarket gasket set for the 57-74 SERVICE oil pans, either have the counterman cross-reference from the numbers which I provided OR ask for a gasket set for a 1975-79 Corvette small block.

Re: Six quart oil pan.

Joe, Thanks for the information. I looked up the pans on ebay, and they don't look like this one. I hope the seller will take it back, as it was advertised as a six quart. Thank again, Tom

Re: Six quart oil pan.

Tom - it may be the 5 quart pan, they had a shorter sump but were otherwise similar in appearance...still had the "longer" section corvette type sump..and they are getting pricey too these days....Craig

[Terry D.]

Thanks Again Joe *NM*

If you can post or e-mail a picture I might be able to ID it and let you know how far "off" the seller was.

The 63-74 "5 quart" pan, if that's what it turns out to be, is, generally, worth more than the "6 quart". So, if that's what it is and you got a good deal on it, don't send it back. I can tell you that if I see a photo of it.

Re: Six quart oil pan.

Joe, I will get a friend of mine to assist me with getting pictures of the pan posted for you to look at. I don't have that capability yet. It will probably be Sunday night at the earliest. If it is something to keep let me know. I really appreciate you and the rest of the members assistance. Tom

Here's the outside of the "6 quart pan" and a link to a picture of the inside.


I learned the hard way as I purchased a 5 qt. that was advertised as a 6 qt.

Re: Six quart oil pan.

Thanks Brian. It looks like I did the same. This pan does not look anything like that one. Thanks for the picture. Tom

Tom please remember that the 6 qt oil pan & power steering are not compatable. Scott
