1968 427 L-71 correct oil pan

[Scott R.]

I am looking at the TIM, pg. 143, no listing for the correct oil pan. I am looking to purchase one, but require part number. Scott

Scott,
All '65 - '74 BB Corvettes used the same oil pan. There are used ones on E-bay or new ones from several of the vendors. Pictures below of what a BB Corvette pan looks like.

The original oil pan was GM #3872429. However, I highly doubt you'd ever find an NOS example as it was discontinued and replaced in October, 1969. Used examples are usually "beat up" or otherwise compromised and have no part number on them for identification.

The last available GM pan was sold under GM #14091356 which included the pan + the external baffle that must be used with this pan for 1965-69 applications. The pan, itself, was GM #14095705 and was never available separately. This pan is virtually identical to the original 1969-74 Corvette oil pans except that there were no welded-on oil pan rail corner reinforcements. These are available in reproduction and can be added without welding and are indescernable. However, the 14091356 is now discontinued without supersesion.

All of the 1965-74 Corvette big block oil pans, including the replacement 14095705, were Corvette-only oil pans and never used or cataloged for any other Chevrolet big block applications.

I followed this same advice from Joe several years ago and ordered a new GM pan for my 454. IIRC I had to order the reinforcements from a repro vendor. Works and looks as original.

Joe,
What are the differences with the other Chevrolet applications that would render those pans useless on Corvettes?

Re: 1968 427 L-71 correct oil pan

Hi Joe, there are several pans for sale on ebay that have trap door, and look ok. I have not found any corvette parts folks who have one, will keep looking thanks for the help, Scott

Re: 1968 427 L-71 correct oil pan

Back maybe 15 years ago, maybe more, I ordered the GM Bigblock Oil Pan from my local Chevy Dealer and that's going on the 427 that's about to go into my 65 L78 Roadster. You can just make out the first '5' part numbers stamped on the pan.

Scott,
Looks like a good, honest candidate. Strip and repaint, make sure the sealing surface is flat...

The non-Corvette big block oil pans can be used on a Corvette except for the following:

1) they will not be correct

2) they are "5 quart" pans whereas the Corvette pans are 6 quarts.

Re: 1968 427 L-71 correct oil pan

Hello Scott, I just completed a rebuild on a 1969 427/435hp engine for a friends 1969 Corvette. He supplied me with a brand-new GM oil pan that was stamped with the number #14095703 and had a "Made in Canada" sticker on it. It is identical to the one pictured on the new engine shown in the previous post. It also came with the windage plate that bolts to the main cap studs. Possibly Joe Lucia can cross this number and give an application for this pan. If it is the same as the #14095705, he has another identical new GM pan with the same numbers stamped on the bottom. If this is correct for your application, I can ask him if he would consider selling it. Again, it is identical to the pan shown on the newly painted engine with the number stamped in the same location. It is possible that the last number on that pan is a 3 and not a 5. The numbers on the two pans my friend has are very clearly stamped. If this helps, let me know and I will contact him.

Re: 1968 427 L-71 correct oil pan

Hi John, Please ask the gentleman if he wants to sell it, my email address is: woodboatfan@gmail.com or he can call me 562-619-4016 thank you very much for all the help you all have given me, Scott

[John P.]

Re: 1968 427 L-71 correct oil pan

Hello Scott, I called and left a message with his wife to call me. I'm sure he will call me tomorrow and I will ask him if he is interested in selling the oil pan. Do you also need the windage tray? If your engine does not have a windage tray installed, you will need to purchase the studs that replace the main cap bolts to mount the tray. You still may want to contact Joe Lucia to see the correct application for this number pan. I will e-mail you as soon as I get an answer, John

sent you a PM.
Looks like you are in Long Beach?
Go see David Sokoloski in LA, Last time I was there, I was amazed at the number of oil pans that guy had!

Re: 1968 427 L-71 correct oil pan

Scott,
If you need an original windage tray, I have one. It is an original "cruved tray" that was used on early 427 engines (including L-88). it was only available in serviceuntil 1969 when it was replaced with the "flat" tray. Below are a few photos. If interested send me a PM.

This early baffle will not function properly with the 14091356 (or the other 1970-74 Corvette oil pans) oil pan due to the relocation of the pan's internal baffle. These pans must use the 3967854 "flat" baffle.
