I am rebuilding a 1955 ford f100. I am having trouble getting a 351 Windsor to fit. I have installed a Mustang II IFS and the oil pan is hitting the cross member. Has anyone had this trouble and what are possible fixes?

 

Do you still have the front sump pan on the 351w

 

The oil pan is the original. It came out of a 1983 F150. Is there a better oil pan to use. I am new to this but having fun doing it.

 

That f150 pan should already be a rear sump. Do you have any pics of where its hitting and of the engine placement

 

I will get some Thanks

 

You might want to check into a fox chassis Mustang engine swap dual sump oil pan.

 

I have a 351W engine with a MII IFS as well. I used the Ford Racing dual sump pan with the rear sump pickup but found that there were still issues with clearance and the front sump drain plug. I modified my pan so that there was minimum clearance between the pump and the pan. I also moved the drain plug from the bottom of the front sump to the rear. I thought that all was good, I tested the pan by putting lacquer thinner in it...any cracks or crevices SHOULD have shown themselves at that point but no, when the engine got to operating temp the pan seaped. No slam on the pan but I had spent too much time on modifying that pan to go any further. Here is the pan that I bought to replace it...I wish I had gone this route FIRST. No front sump, no notch in the center of the pan, extensive baffling, and an additional quart of oil capacity.

also thanks to CharlieLed and Fordman75 for your suggestions

 

A few issues:
Engine is sitting too far back.
Oil pan is a center sump and not a rear sump. Try one like this Ford Performance 351W 5 Quart Engine Swap Oil Pan Kit Rear Sump | Brothers Performance
Here is a pic showing how your engine should setup with the firewall. This is as close and as high as you should go.

 

I will try that Thanks

 

From the photos of my build , you can see that I have a rack and pinion that comes into play. Will the Brothers Performance pan you mentioned fit with that also.

 

I have the oil pan figured out. Now, does anyone know of a good place to get a heater core?

 

I used the following Oil pan from Summit. Worked very well! on my corvette front end install on my 56. Came with everything to do the swap. From your pictures this one would work very well for you and let you get the motor much lower in the chassis.
