73 F100 Advice

Howdy!
I just got myself a 1973 F100 shorty 2 wheel with a 360 (87K), 4 spd. I live in Denver (now) and the body and undercarriage are pretty much flawless.
The motor runs rough and leaks oil though. I found a few bolts on the oil pan that were only finger tight. Even after tightening them, there is still a leak that appears to come from the rear of the motor somewhere. Any advice?
Eventually, I'd like to put in a smaller, more fuel efficient motor so any advice on that would be appreciated too.
Thanks in advance!
I'll go out and take a picture or two and post them soon.

welcome to FTE!

if you want a smaller more efficient engine go with 302 V8 or a 300 I6.

Determine exactly where the leak comes from (wash everything down so you can see the fluid). Wherever it's coming from, replace the gasket.

Thanks Fellas.
Besides new motor mounts and bell housing, what else do I need for an I6 install? (besides tools and knowledge!)

Just to cover all bases, is there any cost benefit of having the existing 360 fixed?

I tried to post a picture and couldn't figure it out. Any advice on this would be appreciated.

Welcome to (FTE)!


I think it is your valve cover gaskets leaking at the rear, and running down
the back of the motor. If not that then back gasket of intake,or rear main
seal!

Personally I would go with the 6 cyl. for efficiency over the 302. My 9 mpg 302 is hardly efficient

what do you do, drive around at 90 mph?

if you were to take those headers off and put the stock muffler back on then you would be gettin' about 3.5 mpg.

I don't drive 90 and I didn't see much of a difference between dual exhaust and manifolds versus dual exhaust and headers honestly. Around town 9 mpg is about what I get.

No I get a little better on the highway, but most of my driving in the past few years. I did get ok mileage when I did an hour long trip on highway loaded down with a jetski in the bed. I'm not too concerned personally with having a gas friendly car honestly, but personally I think I'd give up my 302 for a 6. I do like the sound of the 302 when I get on it though
