Wow that's interesting. It looks as if it holds enough oil near the pickup to avoid running dry from a quick sloshing like a hard corner.

Thanks for the pics! This has got me thinking about building a better oil pan using something like this with trap doors for keeping oil in there.

What's really interesting and why I call it a variant, is that it has a side drain plug like Jeep oil pans.
I bought this from a forum member many years ago - I finally got around to cleaning it up, so I thought I'd take some pics before installing it on my engine.

How tall are the walls? Using that pan, I can see why the spec was 6qt so there is always enough oil to get over the walls.

The pan may be a bit better for cornering, but for drag racing its worthless.

That is interesting. All the ones I've seen have the center oil drain plug.

The 'walls' of the baffle are approx. 3" in height, HOWEVER, the oil doesn't need to get over them - the baffle 'leaks' through to the drain plug. I tried it by filling the pan with water and then removing the drain plug, just to confirm that any oil in the baffle would drain out. There are 5 factory spot welds placed in an arc around the oval cutout of the baffle attaching it to the oil pan - the 'T' shaped cutout has a 'bump' in it creating a channel between the baffle and the pan to allow it to both drain and fill up. It's hard to see in the photos but it's located at the bottom RH corner of the 'T' cutout of the second photo. Edited by sweatlock - Jan/01/2019 at 10:32am |

Agreed. It was supposedly intended for cop cars - and maybe Jeeps? Lol Although as delicate as it is being dependent on the contour of the pan and without a skid plate, I doubt it.

All stock AMC pans are really 6 Qt. The original design calls for 6 but that was one more than the other big 3 makers cars took for an oil change. The marketing hit that AMC would have taken for the increased maintenance cost as compared to the others was deemed unacceptable. The engines were tested at 5 qts and in most situations, they found it didn't hurt to run a qt. down. AMC could not be found to be more costly to maintain, so all literature said 5 Qts. In high speed driving, this lead to oil starvation. Fill a stock pan with 6 Qts and see. It is still below the baffle. Now take away at least 2 Qts for the top end and galleys and see how much is left. Always run 6 Qts in all AMC V8 G-ll/lll engines.
