Going through my stuff and I came across a BBC rear drain bolt type and the pan has a trap door type thingy with baffles... I have a couple of race pans with the same things... Did this come from GM as manufactured this way, or, was Bubba hard at work??? Real neat job of cutting away materiel on the pan bottom.. Can send 4 pics, but, I need an e-mail addy as my computer is a dynosaur... Bought a new Dell Inspiron with Windows Vista replete with Hi-speed, but, that is another tale of friggin' horror dealing with customer service people way way overseas.. Blasted 'puter has been outta service since Feb. and after spending close to a G note, they refuse to send a tech rep to fix the beastie... T.

I believe it is a Corvette piece .
-
If it is what I think it is, that is a Corvette SHP oil pan. It should also be a 5 quart pan.
Nuch

Here's a '65-'74 Corvette BB oil pan - they were all the same.
-
Do you have a pisk of the drain hole?

Red67l78, looks like Pacecarjeff beat me to it... The thing that gets me is, this must've been a heck of a pan with the baffles and "trapdoor" on a hinge type affair, and apparently there was a windage tray that was in fact, specific to this pan. This was a 5 quart rear drain pan... T.

How and where did the windage tray go??? Were there 2 available with this pan or just one, the flat(3967854)??? Ted

All '65-'74 Corvette big-block pans used the 3967854 windage tray (baffle).

Goin' further on the oil pan subject: did GM at one time or another ever extend pan capacity by cutting the sump and re-welding it back together whist adding material, thereby gaining more pan volume.. I guess they did not have the space to go the "kickout" route and starters at this point in time were of the large Delco variety.. Does anyone have a picture of the welding done by GM on an original BBC GM pan??? Why were the oil drain bolts changed from the side of the pan to the rear of the pan or vice versa, from back to side??? Ted

Nope - GM never did any cut-and-weld modifications for added capacity on any production oil pans. Have no idea why the location of the drain plug moved around.
-
bracket racers with little or no money in the racing budget would modify the pans by cutting and welding a section of metal to increase pan capacity. the drain plug was moved to avoid oil flowing on the header tubes when draining the pan.

John,
I saw a MarkIV windage tray on ebay earlier this year that was more rounded than the traditional flat version. If memory serves me, that went for much
bigger bucks than normal for a BBC windage tray. Wish I saved that auction........

Good afternoon!!! John, were the Vette 5 qt. pans all rear oil drain? The one that I have here is "rear" and it looks original, meaning I can't see any side drain hole that is covered up.
I have another BB pan where someone has cut and welded more material back to gain capacity. Pretty bad "hack" job, but, I guess it worked... Again question is, were original Vette pans of 65 - 74 vintage all rear oil drainage types??? Thanks!!! Ted

Yes, all '65-'74 Corvette BB oil pans were the same, and all had rear oil drains; none had side drain plugs. The same was true for SB Corvette oil pans.

Thanks John!!! Ted

Ted,
John Z. is absolutely correct that GM (Chevrolet) never made a (production) cut and wielded pan. However Chev. did make a cut and wielded deep sump pan you could buy over the the counter, used with the following parts:
#3879633... 6qt...deep wielded sump...plug on driver side.
#3879640...semi circular windage tray (Corvette discontinued late 70) I think #3967854 is the later flat version.
#3964255...HD ZL1 pump w/pickup and screen...for deep pan.
This was a drag race pan and not intended for the street. It was used buy the factory teams ( Oh! forgot, Chev. wasn't in racing) and anyone that need a good deep pan for a reasonable price.

Good morning Big Iron aka Bob C... Could I send a few pics of this pan to your E-mail addy as my land line is toooo slow, but, I can send under G-Mail with no problem. I just might have this semi-circular tray you are talkin' about... Thanks! Ted

Sure Ted,
I will try to find some pictures of the deep pan in my files and post them there for those that are interested. The pictures will be scanned so they will not be as good as digital.

Ted,
The pan on the top is the six qt,bottom pan is standard and also shot of 6qt pan by itself.
