Oil pan question
I am putting a 351w and c4 in my 1960 F100. I have a mustang II IFS with a power steering rack already installed. I put a fox body oil pan on the engine and when I lowered it into the engine bay to measure for motor mounts I noticed the front of the Pan is almost touching the power steering rack. And I need to move the motor back about 2 inches to center the motor mounts on the engine over the cross member but I can't cause the pan will hit the rack. Should I be using the old stock oil pan? Any suggestions or input is appreciated. By the way, I bought the universal IFS motor mount kit from Sacramento Ford. Thanks

Which crossmember are you talking about where the engine has to be centered on? The suspension crossmember? Or are you using an engine mount crossmember kit in addition? You certainly don't need two crossmembers there getting in the way of each other. And if your mount kit is just side mounts, they don't have to be centered on the suspension crossmember.
I'm with BB in that it's better to fit your engine where it wants to fit best, and build your mounts accordingly. Worry more about firewall clearance, fan to radiator clearance, header clearance, etc., and let the oil pan work around your suspension crossmember.
A front sump pan will be much deeper and cause even bigger problems than you have now, if you don't think it's fitting the way you want, currently. I promise that's not the answer, unless your plan is to go back 6 or 8 inches, or more, putting the entire sump all the way behind the crossmember, which would likely mean cutting into the firewall.

The crossmember I'm refering to is the mustang II suspension crossmember. The motor mount kit I mentioned is just two brackets that are welded to it. I think your suggestions to place the engine where I want it and build the mounts around it is a good one. Thank you. I did notice that the fox body oil pan straddles the crossmember so closely that if I ever need to remove it I'd have to lift the motor to do so. Is that normal?

Yes. That is the intended fit and design of the setup. That's exactly how the engine fits in a Fox-body car.

The Fox chassis designed oil pan is basically a double sump pan. They are made to fit Fox K-members.
That said, have you looked into using a 351W pan from a 1980's 4x4?
Here's a link to an example: http://cgi.ebay.com/ebaymotors/Ford-...item2eb3dcb57f

The 4x4 pan is fine if you've got the height. It won't let the engine sit as low as the fox pan would. The front "sump" on the fox pan is really just a pocket for the oil pump. It has a drain plug to drain the cup of oil trapped there, because the bottom of the pan over the crossmsmber area is too high for it to all drain back to the main sump. The 4x4 pan has a much lower 'floor' area, about the same level as the bottom of the pump.

It was just a thought. My thinking was along the lines that the sump being rearward, would hang below the crossmember on the backside, since the engine would be moved back a couple inches as stated. I've never used the MII, but do have a Fox.
But the 4x4 pan does have more "bottom"

I was simply adding some clarity, for the folks following along at home. ;-)

Different views all compiled for a common goal to be achieved is what it's all about, IMO. The pictures tell a better story. Also on Epay, where I got that link from, there are true rear sump oil pans.
