V10 swap
99 f250 sd 4x4 245000 miles
It was orginally a company owned farm truck. Just picked it up around the beginning of the year so I could have a winter beater. I live in Michigan so the winters can be a little rough. The truck runs decently for having the right manifold blown off after the cat. got clogged up. The cat. has just been cut off and I gotten, what I could, the studs replaced. Currently 3 of the 5 cyl. have only 1 usable stud. I'm still getting 15mpg but the exhaust leak is so bad that people that don't know think it's a diesel. With the amount of miles and not knowing what caused the cat. to become plugged (by oil). I figured just getting a reman'd engine would be the best bet. Can I put a newer PI engine in without changing a lot of stuff?

A 5 cylinder manifold would belong to a V-10
I would not replace the engine without spending a little time determining the condition of the engine. A few broken exhaust manifold studs are not cause to get a new engine. If you can't repair the studs yourself have a garage do it. Ask them to replace the studs with stainless steel studs.
Catalytic converters wear out and clog. There may not be a reason, it just happens. I had one in a 1995 F-150 clog up. I replaced it with a universal and drove the truck another 80k miles. The truck still ran like a top when I traded it in (240k miles).

He's talking about one bank, where of the 5 cylinders in one bank, he has one stud on each of 3 cylinders.
You can put a newer PI-head engine in, but I would suggest getting the entire wiring harness from a 2000-2001 and the PCM (engine computer) and changing it all out unless you are going to get a custom tune.
The '99 probably has an EGR and DPFE, and the 2000-2004 F-series engines do not. The only way to get rid of that is to use the later wiring harness and PCM, OR get a custom tune that deletes that stuff.
I am not entirely sure if the '99 intake manifold will fit the PI heads, otherwise it would just be a bolt-in.

I did the PI conversion.
You do need the 2000+ intake manifold. The intake ports are quite a bit different. No changes on exhaust side.
You should be able to retain your EGR on the 2000+ intake. The one I found had an EGR blockoff plate on it. Pop it off and put your stock EGR in it. A properly functioning EGR is usually worth at least 1/2 mpg.
'99 wiring harness worked perfect for me. I chose to use brand new 2000+ fuel injectors, but if yours are in good condition, should work fine.
All that is bolt on. Most difficult part is figuring out a new heater coolant hose... '99 uses 5/8" hose at back of right side head. 2000+ has 3/4" at front. Not absolutely positive on the sizes, but you should be able to figure it out. I just used bulk hose and a 3/4 to 5/8 adapter halfway along the run.
It's that easy.

I just purchased an 01' with 224k so please let me know your outcome and how much you pay. I got a great deal on the truck and am now saving to rebuild the way I want to (intake, exhaust, lift, tires, etc.). So im definitely interested in what you end up doing and how much you pay.
Thanks,
Abel

Yeah I guess I took for granted not everyone on this forum would be mechanically inclined. Next time I'll spell out every little detail.
I HAVE A V-10. THE V STANDS FOR THE SHAPE OF THE BLOCK AND THE 10 STANDS FOR HOW MANY CYLINDERS.
Now knowing that there are now 5 cyl. from FORD, I gathered you would have figured I was talking about a single bank of a V-10.
Now that I got that out...
I'm averaging about 15mpg with my V-10 in it's current state. Manifold leak is so bad I've had people ask if my SD is a diesel.
So I was wondering what MPG you guys get from your PIs?

If the exhaust leak is that bad it could have thrown off the A/F ratio on that bank and help seal the fate of the converter. On these modern vehicles with O2 sensors you do not want an exhaust leak before the O2. As a result of the leak your power output is probably down also.
The way it sounds I would assume the truck was driven hard and put away wet so to speak and the truck may not be in the best condition. If that is the case a more viable and cost effective solution would be a slightly used donor engine or to repair what is wrong with the curent engine. If the OG engine is a goner look into a donor further. The 2V PI 6.8l was available in the E-series vans up to 2010(maybe even longer) and the 2V PI 6.8l from 00'-04' in the SD and 00'-05' in the Excursion. If you do some looking around I am confident you can find a donor engine for far less than a reman.
Honestly if your gettin 15mpg I would wager the engine may be better off than you think. I don't get 15mpg out of mine.
