If you google those numbers everything indicates they were used on the L88.

Great to hear from you........searching for 427 GM Deep Performance Oil Pan, 6 quart GM #3879633, in NOS or excellent condition. Also searching for its corresponding windage tray - GM #3879640 and oil pump c/w pick up - GM - #3946023 or GM - #3964255.
Trying to confirm if these part numbers were the same part numbers in the over the counter 1969 GM Hi-Performance catalog. I believe they were.
....one last part to complete my DANA camaro build.
Thanks !

For a friend, I try to be fast! I do get side tracked like I was looking at a Factory part number 3257804 oil cooler installation!
In these old catalogs
Berger lists it as an 8 quart
Nickey as a 7 quart
Motion as a 6 quart!
Thus I think some are adding the filter and probably that oil cooler!
Nickey has a disclaimer- lists under 3369 (or reverse Nickeys number to get your 9633, say Super Duty deep Sump 7 quart (not for Vette or II)! Interesting! The recommended oil pump was Nickey part # 6023 (3946023) (so the real part # would end in 3206????? I will try to look this up, find more, as some of the part numbers in the Nickey catalogs didn’t get reversed).
They were here trying to throw off their competitors, by just listing the last four part numbers and flipping them! In their catalog, I find a few parts where they mixed themselves up and listed the last four as a Nickey part number, without reversing. This pump #3946023 looks like one of those anomalies!
They do show the 3964255 pump (Extended screen pump) is listed, so they sold it with that! All kinds of instructions on mounting it for competition usage!
Pickup should be welded. A flat round pickup shield similar to production should be used to keep from picking up air in the oil. They say drag application, position in back of pan, oval racing right side of pan to be accurate! The road race cars, I have all of the ZL-1 Dry Sump stuff out also!
I bet many of those Muscle Car Dealership builds had the pickup swiveled around to the rear to do it correct to period!
The largest failure as per Traco notes, was any cornering and air getting into the oil pickup! Dry Sump for road racing was a must!
The preferred systems were Weaver and Avaiad.
Back to wet
The pickup should be 1/4 to 3/8 from bottom.
If an oil cooler run, may be necessary to shim oil pump spring 1/8” or install stiffer spring to restore 60psi hot. If spring is shimmed, place shins inside pressure bypass valve rather than at the other end of the spring.
Say run semi circular baffle 3879640 or the Corvette flat tray! The initial L88s only had a 5 quart based pan!
I found some cool Traco Early L88 and aluminum head failures in my notes about a month ago! The two most interesting other than the porosity issues and the weak rod bolts. And other things, is they missed on providing valve clearance on that first patch. Also the aluminum collapsed under the Cylinder head bolt torque! After the initial compression under torque, sometimes you could retirement after letting them sit, and that was good! The head bolt torque though was compromised on the initial single head torque.
The 1968 generation, they corrected these issues!
Back to oil pan, they do recommend on a performance build a magnetic drain plug!
I write all of this, as I wanted to cover the options, as these Dealerships (Dana, Berger, Briggs, Motion, And others were putting these tricks into the Tuner 427s that they were offering!
I am liking the research on what each guy was using on their builds from the Aftermarket. He had their particular favorite parts.
The baffle and pan are listed as Passenger application 396-427 Family!
I am going to look up the motion 482 ZLX next, and the Aluminum 454. I also have out a lot of the Reynolds stuff too!
I was just looking at the Briggs Greenwood parts, and they had a full floating pickup as they couldn’t Dry Sump under the rules! They offered Special built Pans, depending on drag or road racing!
Nickey at the L88 intro was offering a Chevelle and a Camaro Special Go Fast Oil pump Part #7284 (so if we flip that to get the real part number, it ends in 4827!
3469 (real part ends # 9643) oil pump in this same near end 1967 parts catalog, says use only with pan 3369 (real part # ends 9633).

Berger lists it as an 8 quart

those parts were from a 366 cu in heavy duty truck engine. those are the correct part numbers from the 10-3-69 heavy duty parts list. the correct oil pump for pan 633 is 023 as the pick up was welded to the pump. the baffle was 640

Look here: It says "(exc, corvette)" for 3879633

Damn you guys are fast, I didn’t even get a chance to add more edits!
I will add, for correctness, it depends on exactly what time frame the engine was assembled, and from who! As you could generally get like short block or complete, or semi Conplete! Each dealership, played some with cost, and swapped over the production pieces!

Cool I found the 023 pump too! It looks like the early pumps were sold with the pickup loose, so you could configure to your application. When they made it a definite Production car replacement part, they welded it were they thought you should have it positioned!

I grabbed the Grumpy Jenkins stuff and he tried the ZL-1 and scrapped that idea and ran the Can Am Reynolds blocks in his Drag cars!
I just got done done looking at like Kelly Chadwick, Doug Thorley, Pisano Brorhers, Bruce Larson, etc notes! Fun fun fun! Now I am trying to figure out who ran the fastest Fuel Funny Car, well Gas is interesting to, as some tracks weren’t insured for fuel!
I will I’ll now be up all night into this new path of Drag race 427 Rat Funny Car evolution, before the Hemi Aftermarket Engines ended all Chevrolet engine installs! And don’t get me started on Jr Fuel Dragsters or Jr Gas, as I am a Small Block guy by nature!
And I got to go, I am going to reread about Peters Freight Train build!

Also I would ran the later ZL-1 oil pump with the 1.3 inch gears (Part # 3969870). And Pan #3977591 and baffle #3967854. I only have high end Small Block parts in real life, and only dabbled with Ownership of one 396 Big Block 1966 Chevelle, so I haven’t and never had a chance to lay these down side by side and compare Big Block evolution stuff! These parts just mentioned became the RPO L88/LS7 stuff.
Just saying! I like the most modern rendition for the engine Family on things. Just saying!

I appreciate everyone chiming in to help clarify the Hi Performance GM part numbers. My engine was assembled in Jan /69 from DANA Chevrolet. So my original assumptions were close with the exception of the #3964255 pump (I have seen this pump on a few 67 427 vettes).
The factory part numbers for the 69 time frame would have been:
6 quart GM oil pan - #3879633
Windage tray baffle - #3879640
Pump - #3946023, c/w deep pick up tube to match pan. .........

I got a whole lot more stuff that I can dig out! I think I remember Vette Vues article on ZL-1 parts! Don’t know if this is the later aftermarket (GM Parts supply) or the original build. I do know I have ran across specific ZL-1 lists! I will get into this a little more. As I was working on this about a year or more ago! We had threads going on Penske, Motion, Traco, Etc etc etc.
I m liking this Drag history stuff! I over the last hour got side tracked on the 1966 NHRA season relegating Funny cars or A/FX blown on Fuel (nitro mixes) to run with the Dragsters, while AHRA was recognizing a Funny Car Class. AHRA tracks started making the money with the match racing. 1967, started running the big 16, then 32, then 64 Car Fields! I grew up with this s my Dad ran a 64 Corvette in B/SP gas class in AHRA mostly at our neighborhood track Lions! He drove mostly the run what you brung Wednesday nite stuff, but did a few Saturday night qualifiers to get into the 8 or 16 car typical brackets. He made one or two 16 brackets. So this hits home! OCIR wasn’t opened yet, but was getting built (opened Aug 1967). They were all modern, and went NHRA opposite of Lions with Irwindale (NHRA sanctioned too). My Dad had to sell that car, and then got the DANA Chevrolet C3 from Armstrong, entered that in the 2nd All Corvette Drags in 1969. One bad picture of it only.
But I will keep an eye out for Big Block development for this thread topic as I relive SoCal action! The C2 had Mondello done heads, the C3 got modded more with Blair ported heads, and Reath balancing!

Ok back to drag racing!
Oh oh we haven’t emailed in a while! But I have been Anti Social to everyone of late!
I found a copy of the Dana Sales Pamphlet from those years! I also discovered the Can Am car and USRRC car engine guy. Slipping my mind right now!
My Dad’s DANA Chevrolet car, I decided to not buy it from my Porsche loving brother, after my Father passed. I decided to just keep my own C3 for now, instead of selling it to do the deal! It is now getting the CVC/Apex 5 Link from the 1970s, a all new Tom’s Differential 10 bolt unit (fresh), and a full Bowtie engine, pulling the Production stout 010 4-bolt Main LT-1, and the mostly Guldstrand suspension goodies and dual adjust vintage Konis, keeping the Global West, Pole Position, Herb Adams, Guldstrand’s 5-Link, Koni coilovers on my race C2 with the HD ROD 6 Speed, and Toms Diff 12 bolt (new NOS unit)!
I also found the DANA ad for my Red on Red used car C2 Slalom Car!
So making progress! I also scored the limited Special Offering 1/18 Scale yellow DANA Chevrolet 1969 Camaro! Had to pay some bucks for that thing! Ouch! So I now have an impressive row of Chevrolet muscle (Harrell 69 Pro stock, Grumpy cars from the Nova Chevy II to the the Vega Pro Stock and all of the Camaro, The DANA Camaros in between, a bunch of Motion cars, the Liberman Jungle Funny Car from Briggs Chevrolet and an Honest Charley sponsored one too, and a Bruce Larson USA-1 Funny Car Gen 2 Camaro! I hope the Chevelle one day gets done! Having fun, but the DANA yellow Camaro was a find!
I was also also trying to find a guy on the modeling 3D printing Shapeways site to cut out of maybe aluminum DANA emblems!
So like you, always having fun !
