I have a customer who needs an oil pan for a BB A body drag race car. The car is a 1975 Dart so it should have all late model suspension and steering on it. I'm not sure which K frame that he has, I need to find out. The car isn't super fast, maybe 10 or 11 second car. He is making around 650 hp. I think a 7 qt pan would be fine if there is one that actually bolts in and fits.

Last time I built a late model A body with a BB I found that very few oil pans fit. I ended up using a reproduction OEM pan. It worked, but I would've liked to have more capacity.

I actually just bought the milodon one on the left for my 383 Demon project. I've used a moroso 7qt deep sump on a 440 Duster too. No issues.
I'm using a small block 68-72 style k member with Schumacher mounts. This will be my 5th bb a body I'm building.

Do you know if the car sits very low or does it have a decent ride height?
I had a low deck big block in my 75 Dart Sport using the Moroso 8 quart oil pan I originally bought in the late 90s. Looking at current pictures on Summit Racing they appear to have changed it to a very square shape, so I do not know if it would still fit the same.
Mancini Racing currently has oil pans under their brand name that appear to be the same shape. I don't use a very low ride height because it is mostly a street car. And it never bottomed out on anything anywhere I went on crappy Michigan roads.

I don't know if the flared sump on 7 qt. Milodon big block pans will cause the same problems, but on their 7 qt small block pans a little "V" has to be cut out of the K-frame lip to help the right-front corner of the pan to clear during R&R. Also, most small block headers won't work on the passenger side, again, because of the flared sump. TTI & Dougs clear. I think there was one other particular Hooker or Hedman, but I don't recall the brand or #.

Gotta watch speed bumps, edge of pavement drop offs & wheelstands. The extra weight of a big block will be less forgiving.
I believe OEM style Hemi pans are 6qt but not sure about the fit and Steffs has a 6 qt, but it's very expensive.

Not just R&R. The Milodon small block pan you refer to won't even go in without hard contact. That V is to make it fit. I had to do that on the current setup with my 360 in the same 75 Dart Sport.
 
I did a BB Duster project several years ago with the Mancini pan and it required mods to the pan before it would fit. A notch had to be cut for the idler arm clearance. I tried the Milodon road race pan in my '72 Duster and it wouldn't fit. It hit several spots including the K frame and the steering linkage.

I think the idler arm and pitman arm are different from 73-76. One hangs down and the stud points up and the other is higher and the stud points down, going by memory. I should clarify, mine was a 75 model year Dart Sport, slant six k-frame, and it was using the Schumacher slant six to big block conversion engine mounts.

Sorry for leaving that out of the original reply.
 
I ran a 7 quart Milodon pan on my 440 Duster, I don't recall it having any clearance issues, but with how deep the sump was, I sure had ground clearance issues and the pan got beat up. I switched to a Hemi pan, which required switching to the later style steering, and I ran into issues with the idler arm and center link hitting it.
 
milodon road race pan, 400 in a 68 cuda with 73+ K, 68 linkage, manual box, schumacher mounts, tti headers. K is modded per their instructions.

it fits but everything is *tight* down there.
 
My 68 has 73-up steering gear so this should be apples to apples. The 511has a 440 Source 66-69 hemi pan which is 6 qt + 1 qt filter. It hangs 3/4" ish below the factory k. I planned on modifying a b body hemi skid plate. That plan didn't materialize due to the QA1 k swap and belly pan requirements. If you'd like I can get some pictures. The 73-up steering linkage game some clearance instead of the very very little I had with the 68 steering parts.

I’m pretty sure the Milodon Super Stock pan fits, but the center link goes through the pan and some guys hate that.
 
I’ve used the aluminum deep pan from 440 source. 74 duster with dc k frame. These are the only pics I have. There was a windage tray and a 1/2 inch thick BCR girdle sandwiched in between the pan and block. Kim

Andy, I have a ‘75 K. The standard Milodon deep pan fit but hung down below the K.

The road race pan you have pictured on the left required me to cut the corners on the K-frame spool mounts.

Here you can see how low the standard deep pan was hanging down. Which became a huge problem when I hit a monster pothole in a rainstorm. It almost ripped the drain plug out. I lost several quarts in a minute. Realized what had happened before I lost oil pressure!

Modification to passenger side spool mount and notch in the lip:

With pan installed showing clearance on driver's side after modification:

Biggest plus is that the pan is above the K now.
