bigbluthng,

I've used the mid sump pan in rwd '67-'72, but I modified the firewall to allow more room at the driver's side head, and allow moving the engine back a bit more. Not sure if the pan would clear w/o that.

The rear sump pan from an early 80s Caddy 368cid engine will fit on your 500cid, but you will need a oil pickup tube from a 70-76 rear sump Eldorado 500 cid, which may be available at your auto parts store. The 368 PU tube will not work on a 472/500cid.

Keith,

The '68-'78 eldo rear sump pu tube is no longer available, anywhere, afaik. Melling made it for everybody, and they stopped making it.

Keith,

  Could you explain why the 368 pick up will not work on a 472/500?  The reason I'm asking is because I was told earlier that it will fit a 472. I have both a 75 Eldo 500 pan & a 81 Eldo 368 pan. The 368 pan is at least 1" deeper than the 500 pan. I do not have a pick up for the 368 pan. The rear sump 368 pan looks to be about perfect for a 4X4 application. It has a small lip around the sump to help keep the oil in the sump & looks to be the easiest to modify.

Thanks
~JM~

JM,

Luxlx did a nice job converting the front sump, but you still need a pu tube for it. It looks to me that
a modified '79-'84 [rwd mid sump] pu tube is out only option at this point for a rear sump pan, be it
a 68-78 eldo or built pan. The mid sump pu tube is still available.

Btw, iirc, flashcraft sells pre-cut kits to do what luxlx did with his pan.   
Dave
p.s. - if anyone finds any old stock '68-'78 eldo pu tubes on a shelf somewhere, please let me know.
There's a thread here somewhere, in which I posted part #s from every source that used to sell the
Melling pu tube for 68-78.

yup, i sure can. i thought about fabbing up my own but i needed to see a pan up close so i can get some ideas. i have access to a brake, and shear, and my buddy has a tubing bender so i might be able to pull this off. i just saw luxlx's pics. he's my new hero!  :yes:

k10caddy,

Not sure, but it looks to me that the mid sump pu tube could be lenthened for rear sump. You can usually find misc used pu tubes at any engine shop for cheap/free to use for extension parts. Make tube joints nice and flush and de-burr inside. A tight square fit will prevent weld from burning through to inside, blocking flow.

Btw - I find it interesting that the 68-78 rear sump pu tube's pickup screen is toward the front of the sump, and the tube heads rearward, before making a u-turn and heading to the front. Not so with the mid-sump tube.

The rear sump 368 uses a pick up tube which bolts to the passenger side of the block whereas the 500 bolts to the driver's side. I can't see any way it could work. However, I was able to bolt up a 368 pan to my 500 block with zero modification. For a 4x4 application, a 368 pan offers the most rear sump available in a OEM pan. If 70-76 Eldo tubes are no longer available, I would think a 425 tube could be modified to fit.
