Im putting 88 mustang 302 ho in my 77 f100 and the mustang has a rear sump oil pan and the motor in my truck is a front sump oil pan . Will i have to change the oil pans out or can i get away with the mustang oil pan (rear srump)?

 

Come on guy's , some one has to know!

 

First what engine do you have now? Check your engine mounts and perches...and also what type of transmission do you have? Keeping it or replacing it as well?

I just did almost the same thing...I put a 351W in my 78, (had a 351M front sump). I was told by lots of people I would have to change my oil pan to a front sump...never could get a clear answer as to what would work (pan wise), so I tried it...guess what it worked. Have about 3" clearance with the rear sump pump 351W. Don't know if that will be the case in your situation...but just yesterday I put mine in...Hope it helps...Everyone on here gives great advise and are SUPER HELPFUL! The best place for info you will find! Use it!

 

I just swapped, over the weekend, a 351m w/ the front sump to a 400 with a rear sump in my 78. No problems at all!! Its actually alot better because now when I change the oil it won't run out all over the x-member. No clearance issues at all.

 

The motor in the truck is a 302 as well
