i hace a 360 in my 72 f250 and am considering switching to a 390 what are your opinions or what should i do to beef it up both 360 and 390 for best results on and off road.
All a 360 is is a de-stroked 390. Same block, same pistons, same head, etc. I believe the difference is in the crank and rods. No point in exchanging a 360 for a 390. Now, building that 360 up to a 410 with a 428 crank, THAT would be worthwhile. You will find all the info and more that you need on this in the FE forum, btw.
just build your engine to obtain maximum low end torque rather than a high reving hp monster. but its all relative in what kinda 4 wheeling you will be doing. a mudbogger will need high horsepower.
Get the crank and rods from a 390 put them in the 360 block you have. This will increase torque. add some headers 2.5" dual exhaust with a H pipe. Get a 4V intake and a 650cfm carb. while you are in there you might as well upgrade the cam too something that makes alot of torque.
i have heard the 390's have oiling problems. they tend to wear out faster b/c it can't get the oil around as much as it should. that's why they didn't last for very long. stick to the tried and true 460, hehe

I don't know about oiling problems, I have had several 390s that were still running strong after 200k miles without even pulling a valve cover, and they still had plenty of oil preasure, and I know of one that went 320,000miles before the oil pump went out put in a new pump, and kept going.
as to not lasting very long (I assume you mean ford quit building them) the lasted alot longer than some engines, and ford quit because of the epa not because of problems with the engine, by the time they put the smog pieces required to pass epa standards they were so choked down they couldn't make any HP out of them. which is why they quit putting them in the cars first, the pickup standard were a couple of years behind, and they could still put them into them for a couple of years.
that's just what i have heard man! i dunno! I do know that the truck in my galler (the one in the pic w/o the front tire/wheel, lol) has a 390 and he has blown it up 4 or 5 times in the past year and everytime we rebuilt it it was b/c lack of oil!
He may have a problem with that particular block. Restricted oil galley or something. If you put a HV oil pump in a stock FE without restricting the oil passage to the rockers you can pump the oilpan dry at high rpm. I have spent alot of time in the FE forum, it is not uncommon for people to drive these engines with little to no oil pressure at idle. But the FE keeps running And like memtioned above, They seem to run for a very long time. More than 200,000 is common place.
I have a HiPo 390 with edelbrock Performer RPM heads , intake, cam, SpeedPro forged pistons, Edelbrock Performer 750Cfm carb Melling HV oil pump. No oil mods at all, the Edelbrock heads come with smaller oil passages to the rockers. It is doing just fine. And it is 230lbs lighter than a stock 460..
The FE oiling system design is not the most impressive. Because of this there are a few common steps that are typically done to improve the system when the engines rebuilt/built up. However, the system is plenty adequate for the stock/mild FEs and they will run darn near forever without any modifications to the oiling system. FE's are great engines, just an old design. I wouldn't say that they have a "problem" with their oiling system, just that theres room for improvement.
