Have a 351w out of an econoline will the dual sump pan still work? Or do I have to get a bronco specific. I have a 1 in body lift and 2.5 in suspension lift.

I'm running a stock 96 E350 van pan on my 351W. Same BL and SL as you.

No issues for me BUT I don't offroad. Street only......

I don't believe there is an EB pan for 351Ws. The OE 289-302 EB pan can have the rear main cap portion of a 351W welded on to make a real 351W EB pan. Duff's did this 45 yrs. ago. Now the best choice is the Ford '80s Panther (Crown Vic) body duel sump 351W pan. The front axle/differential will hit these on full compression, but that's the best production pan there is for the 351W.

It looks like Wild Horses and Duffs sell a 351W oil pan for the early broncos that clears the D44 and cross member. I am about to do a 351w swap myself.

I just used the 351w swap pan from Wildhorses. My only advise would be to buy an oil pan stud kit and oil pan stiffener rails. I am not sure I would have gotten it installed leak free without both those things, maybe if you oversize the holes one size. It wasn't a perfect fit as with most aftermarket parts these days. I still think it is the easiest way to get it done and I would do it again if I had to.

A body lift has zero affect on oil pan fit.
A suspension lift doesn't change the dynamic clearance, unless you change the bumpstops. the static clearance will go up with a suspension lift, but you need to account for dynamic suspension travel as you drive.
Econolines actually had a couple different oil pans over the years. There is a mid-sump Econoline pan that also exists. Pictures of it are in the Tom Monroe small block ford rebuild book.

The fact remains. There is no 351W pan made for the EB chassis. ALL the vendors sell the '80s Panther body 351W pan. The only difference is the price and the distance it needs to be shipped. ALL these pans will be hit by some part of the front axle when the suspension is fully compressed. I'm in the same boat, running the same pan. The difference is that I'm not happy about it. There are some of the early James Duff 351W pans, converted from real EB pans, but I haven't found one yet.

Milodon makes a 351w 4x4 pan. Its also got a notch in the back corner for the driveshaft if you run a high pinion 44. The pick up is sold separate. I think it's like 450 for the pan and pickup.

I will agree there is no FACTORY pan. But there is an aftermarket pan with the clipped corner for diff clearance that is specific to a 351W in a Bronco chassis. So it does exist, just not a cheap stock replacement or off a junkyard engine.

I've seen the Milodons. That's just their 351 Mustang duel sump pan with a corner of the rear sump cut off. It's clearly not a pan designed from the ground up, for the EB chassis. It's a cheap short cut, something Bubba would make in his basement. It's not well thought out and not worth 460 bucks. I would pay that for one of the early Duff's 351 conversions of OE 302 pans, not the for the Milodon.

As I recall Stacey David use that same pan when he built Crazy Horse nearly 20 years ago. So that Bronco specific off-road pan from Milodon has been around for a very very long time

Crazy Horse was a stroked 302 (347 I believe). Milodon makes both pans for the Bronco chassis, 302 based and 351 based.

There's a guy who shows up to the long beach hot rod swap meet maybe once a year with like new milodon plans for about a third of the price. I think they're demos or something. I think I paid 100 for the 351w pan without the pickup. Swap meet is tomorrow morning(7/14) for any of you so cal guys. 75and older vehicles park in preferred free. If you're in preferred you can bring your own cooler.

To up date my earlier post. I ended up cutting the rear main saddle off the EB 289/302 pan to fit the 351w engine block. Few welders are willing to even try welding this. I did find one and have exactly what I wanted. The dip stick is in the same place as OE. In fact, so far, no one can ID the 351 swap. I use the OE intake and exhaust manifolds, front dress, and air cleaner. It only reaffirms the fact that Ford should have offered the 351W as an option starting in 1969. I remember reading that Ford couldn't do that, but clearly they could have. They never understood the enduring appeal of EBs. The 2020 up Broncos couldn't reestablish the EB mystique.

This is what my 351w pan looks like. I run a 2-1/2" suspension lift and it only on one area it "self clearanced".
This pic was taken when I did a "gasket delete procedure" with my mig welder where the dipstick tube mounts.

Do you have any photos of the modified pan? I have a Canton deep sump pan on my 351W stroker. They market it as being an early Bronco-specific pan. It also has a cutout at the left rear corner for clearance, but it's not enough. With the suspension compressed the front driveshaft barely clips it. And they don't fabricate the pan from scratch, it appears to start out as an aftermarket copy of a rear sump 351W pan. Not a great one, the drain ports are poorly made with a rough sealing surface so they leak despite fresh copper washers etc.

I also have a dented Ford Performance, AKA Panther pan, and the corresponding oil pickup tube. I could use it as the donor for the rear saddle. Tempting to make my own "Duffs" pan. What oil pump pickup tube are you using?
