390or391
I've built a 390 and am installing it in a 1967 F-100.
My problem is that my oil pan does not hold enough oil for the engine, it is the right pan (5qts with filter).I'm thinking about installing a 391 oil pan but I don't know if I have to raise the engine up 1 inch or if if will fit as is.
if any one has any info or input, Iwould like to here from you.

Burman, There is a train load of FEs with 5 qt. pans that have held enough ooil for them for over 40 years now. Why is it not enough for your's??

I believe the pan can hold an extra quart and it was a racing trick in the 60's to help prevent the pump from sucking dry under hard acelleration. It may also be that you need to have a baffled pan instead of a windage tray, if you are accelerating hard enough you might just be pushing the oil away from your pickup, did you also check and make sure that your pickup was no more than 1/2" off of the oil pan floor?

I have a high volume pump in my truck and probably looser bearing clearances and the only time I suck dry is if I'm quite a bit low on oil. You might also want to take some #76 or so holley Jets and just put them in the hole in your head where the oil flows into your rocker shafts, it might help a little, doesn't show on the gauge much, but it helps if the shafts/rockers let much oil out, and should at least slow down how quick your pan runs dry.

Can't answer your original question since I've never seen a 391 pan, but I know that there are aftermarket high volume oil pans out there. They are a little pricey, but it sounds like you've got a lot invested in your set-up so a couple hundred more shouldn't break the bank. At least it will protect your investment.
If you restrict the oil flow to the rocker shafts make sure you clean the shafts out extremely good first. My machinist did mine, but he warned me that he has seen a lot of burned-up rockers and shafts.

[font size="1" color="#FF0000"]LAST EDITED ON 30-Jan-01 AT 01:01 AM (EST)[/font][p]only problem is I think most of the aftermarket high volume pans wont fit the crossmember that's about a inch below the bottom of the stock pan, maybe baffling will be your only option, because to me 4-4 1/2 quarts of oil is a lot of oil in the top end of a engine, almost too much, like it sucks up two quarts but the rest is pushed out from the oil pan pickup so the pump starts sucking air

My 1969 Ford Truck Shop Manual which is published by the Ford Motor Company states that the oil capacity for the 360/390 engines is 5 Qt. However, I think a lot of people miss the little footnote below that says " *Add 1Qt. when changing filter."

I have the HV/HP oil pump and I went with the Milodon 9 qt pan. This is a deep sump that sits lower than the stock 4x4 one. It's a rear sump with baffles and cost about $350 with the required pickup tube. I also run the windage tray and fast return spring shields under the valve train.
The Milodon has the large part at the very back of the engine, the front part is about 4" and the back part is about 11" It is designed for the 4x4 but it might work on the 2WD. Rear sumps are much better for the FE (if they'll fit)
Milodon makes the front sump if you can't run a rear sump.

I's a street truck that towes a gross combine weight of 12,500lbs,and it does accellerate hard enough to pop the front springs. And it does some weakend racing.
A 391 pan holds about 8qts and is almost square but has a rear sump. You will find 391's in F-600 and larger truck. I have talked to the machine shop(since the engine has already blown-up)about restricting the oil to the heads, and baffling the the pan. He said he would talk it over with his fellow ford racing buddies,but he thinks it is the way to go..
FE427TP- your right. None of the aftermarket pan manufacters make a larger pan to fit the cross member clearance problem on 2wd F-100,and the rear deap sumps for 4x4 won't clear the steering linkages.I always thought that any time you had the orginal under hood sticker that gave you the engine specs. that the sticker superceadethe repair manual, especially whwn the dip stick agreed with the specs. on the sticker.My sticker says 5qts with filter. As far as the cost of this engine, right now it stands at $9,790 and that does not include what is coming.
jowilker- Any info you bud can spare wil be welcome.
I would like to thank everyone for you info and ideas. Thanks..
