351W oil pan

[hunter1]

I have this oil pan that was on a 351W in a wrecked 72' bronco that I got for parts. i've noticed that the pan is damaged on one side and looks like it had been rubbing. I am currently building a 351 for my project. Can anyone tell what this was originally in and would it fit? After looking more closely at the damage to the pan, i was thinking it may have been massaged with a hammer for fit.

It either self clearanced on the front axle diff or someone massaged with a hammper to clear.

It is from a 1969 mustang. That is why it does not have clearance for a 4x4 axle. You can buy a pan that will fit (aftermarket) or maybe from a 4x4 truck or full sized bronco.

It's not from a '69 Mustang. The only Mustang that had a 351 double sump pan was the '95 Cobra R. Those pans were designed for '79-'91 Crown Victoria police interceptors, where the vast majority were used. All the '69-'71 351W Mustangs had front sump pans. The duel sump 351W pans turned out to be the low buck choice for 351 engine swaps into Broncos. They're not Bronco pans either, but Ford never made a 351W pan for early Broncos. So the double sumps work "most" of the time in EBs, or until the front suspension bottoms out.

Makes sense that it is from a 79’ vehicle. The engine numbers came back as a full size such as an LTD. the oil pan was originally gray and had a more modern looking calibration sticker on it.

D9 for an engineering date code means it first saw service in '79 and so long as nothing changed was used for years after that. Mid 80's had a lot of 351 full size cars with that pan on it. Nothing special.

As mentioned, clearance can be an issue. Typically there will be a dent in the pan from either a hammer or the front axle, either one will do it. Even with a lift, unless the bumpstops have been raised.

I still think it's a shame Ford or even someone else didn't make a stamping die based on the 289/302 '66-'77 Bronco oil pan, with a larger rear main bearing saddle and a deeper front sump to clear the 351 oil pump. With that the 351 engine swaps would be far easier and the pan wouldn't be hit by any part of the front axle. The pick up tube has to be modified too. I did all this with the help of a talented welder. So I know it works. From '69 on, Ford had the 351 and the Broncos needed the low end torque that 351s offered. Why they didn't offer it is a mystery.

1970s Ford Econoline van with a 351 Windsor that is your pan.
