I am going to put a mustang II front suspention under the front of my 65 in the next couple of months. I got to looking at the oil pan on the 300 that is in the truck and I am afraid the pan is going to hit the new mustang II crossmember. Is there any way I could convert the 300 from a front sump pan to a rear sump? Any help would be appreciated, THANKS

 

My 90 has a rear sump pan on it, so I would expect to find a rear sump set up on anything from 88-96 and maybe a few others. The only problem might be getting the pan to fit your block; I believe all the EFI engines use a one piece rear main seal that requires a different pan.

 

79-earlier 4wd, all 80-later trucks use rear sump pans. Make sure to get the pickup tube, special main stud with the pan. Rear sumps also use a different dipstick/tube.

 

I'm doing the same thing on my project 300, Except I'm going from a mid sump to a rear. If you do indeed have a front sump, that may be worth some $$.
The rear sump pan will fit fine (bolt up wise). I have not looked into the rear main seal - I've only seen one piece seals...the newer gasket should work even better that the old 4 piece. You will need the rear sump pickup too along with the a main bolt that has the extra length of thread on it to support the longer pickup tube. The biggest obstacle I've seen so far is fabbing a custom dipstick mount in the pan. Some select late eightyish rear sump pans have sticks in the pan - that would be ideal to find. I have seen an older 70's motor once with a rear sump too - very rare. I'm holding on the stick holder fab work untill I get the low end assembled. Good luck!

 

(tetra) Are you also installing the mustang II in your truck? If so what model is it and what crossmember kit are you using? I just got my air ride kit in with the tubular lower control arms, but I have not ordered the crossmember yet.

 

If you want a dipstick, get a pan from an 80-81 F-series pickup. Everything else had the tube through the block. I have one of these pans on my truck right now. I would higly recommend that if you get a used one, re-seal the plate that the dipstick tube goes through. They tend to leak like a sieve.

 

My project 300 is going into my 79 F100. Sorry I can't be of help regarding the Xmember.
