I would like to install a Ford Racing rear sump kit M-6675-A50 in a 1947 COE with a one ton van late model front clip. But the description states it fits only 83-01 engines. I have a 1973 block and am wondering the problem it has with the earlier blocks?
The 5.0 type pan uses a casting lip and dipstick that goes through the side of the block. Otherwise you can use the old pan on the newer engine but you need to make a custom setup to go the other way.
Thanks Algon. Since my dip stick is in the very front, can I just shorten it to work in the rear sump pan? Is there any oil level in the front to measure?
Side of the BLOCK? Think it's the side of the pan. If the pan you want to use has the tube in the side of the pan, use it & tap/plug your stock dipstick hole. If the rear sump pan doesn't have a DS in the side of the pan cut one out of a pan & weld it on yours. On the 318 Mopar the rear sump pan used a 3' long stick that has a guide channel on the oil pan for it to get the proper measure, don't think you can just stick a longer stck in it. You might put 4 qts in the new pan, off the engine, & see if any oil is @ the front of the pan.
Side of the BLOCK? Yes side of the block. The kit uses a late model ford block and you cant use the dipstick in the timing cover to check the oil. I just used this kit and got lucky with my block it had been changed over to late model. My machine shop said he could drill a dipstick hole if mine didnt have one. You might check your local machine shop. Your other option is a early pan with a dipstick in the side of the pan. I found listing for it but had no luck coming up with one.
The late blocks have the dipstick in the side of the block,I have 4 sitting here,2 5 liters and 2 351s.You will not be able to use your dipstick in the front,the oil goes to the lowest part of the pan.If you can find a mid 70s Van they had the dipstick in the side of the pan,I've had 3 of those Vans. ROY.
No!!! The front sump will always read full on the dip stick if you use a rear sump pan and a timing cover dipstick. Been there, did that. 79-80 Fox body Fords use a rear sump with the dipstick in the side of the pan, Mustang, Fairmont, T-Bird with V-8.
Moroso should have a kit to install the dip stick anywhere in the pan you like, very simple solution, and NO you cant measure the oil from the front small sump. TR.
Thought he was talking a real rear sump pan, not the double sump. Some have drained only the front one & wondered why the oil was too high!
I used the dual sump on my 302 and welded a drain back tube from front to rear since front drain would have been right over the crossmember.
I see now where the small sump in the front would give a false oil level reading. Too bad Ford Racing just didn't design a true rear sump oil pan. Guess that small sump in the front is there for a good reason. I would really like to keep using the front dip stick. Looks like it would work well for my COE. Maybe someone makes a stock looking oil pan with without a mini-sump in the front. A van oil pan maybe a great option.
Old Ford motors are front-sump because they have their distributor and oil pump in front. Old Chevy motors are rear-sump because they have their distributor and oil pump in back. The Fox 'rear sump' pans need enough of a front sump to provide room for the pump, and a long pickup to extend back to the rear sump. Unless you want to dry-sump it with an external belt-drive pump. It used to be typical to put the pump in the pan (BMW pumps were chain-driven off the front of the crank), some engine designs have the pump externally mounted (e.g. Buick V6 with the distributor, oil pump drive, and oil pump on the front cover) but starting around the late '70s IIRC most newer designs (including the gen3/gen4 Chevy V8 that have no distributor) make the pump a flat gerotor ***embly that fits over the crank snout and takes no pan real estate. There's production pans for those things that put the sump in the front, the middle, the rear, or dry-sump LS7/LS9. Part of the reason you can put an LS2/LS3 in anything from a Miata on up.
The reason for the dual sump was the pan was shaped to go over the stock crossmember in the FOX cars. They needed the clearance in the front for the pump itself and then raised the center to go over the crossmember, then back down for the rear sump. This is the infamous E150 Van Pan
