Rick, I found a text in web about pan.
"The first consideration is the
oil pan on your engine. Ford engines of the 1960's and 1970's generally used front sump
oil pans. These will not fit the Ranger/Bronco II chassis properly. Instead, a rear sump or dual sump
oil pan must be used. Rear sump oil pans are originally used on full-sized trucks and Econoline vans and hold 6 quarts of oil. They are the preferred oil pan as the extra quart of oil is of somewhat of an advantage for performance and off-road applications.
The other choice is a dual sump oil pan. These are easy to spot because they literally have two sumps, one at the front and another at the rear with a drain plug on each. The front sump is for clearance to the oil pump and the rear sump is the reservoir for the oil. The biggest advantage to the dual sump pans is that the engine may be situated about half an inch lower in the chassis. Dual sump pans were originally installed on vehicles like 1979 and newer Mustangs, 1980's Crown Victoria's and Grand Marquis, and a few others.
Please note, 1980's Crown Victoria police cars are the only vehicles with a 351W that use the dual sump oil pan. If you need the dual sump pan for a 351W, you'll have to find one from a police car or order one for that application.
Ford Racing is currently offering a dual sump oil pan kit for the 351W which contains the oil pan, pick up tube, attaching main stud, dipstick and tube. You can get it from Summit Racing Part# FMS-M6675A58 or just the pan as Part# SUM-123458."
Do you know if exist dual sump oil pan for 429 engine?
And what is your opinion about. Is it better than front sump that is most used?
Thanks again.
