swapping a 99 from f250 into 97 eddie

[Nightmare99]

just wanting to know any info from people with EXPERIENCE with this swap or close type of swap. i bought a 1999 5.4 out of a f250 (vin L) and already im noticing some changes i have to swap from old 5.4. like the Remote oil filter?cooler setup..what else? and my old 5.4 the intake throttle body is straigtht forward, the f250 5.4 is at a 45..will throttle body change correct this or not...and yes i know "just compare them etc etc" but my old 5.4 is 100% in individual pieces and have yet to get out to shop to start, just wanting alil info first...and also for those thinking it..This is NOT my first engine swap or build.....by far

Is your vehicle the same year?

I'd think you'll probably be ok. You may have to swap out your throttle body and a few items to match up to the intake. Neither should have the PI heads and both should have the aluminum intake. I'd compare all the cooling ports and hoses though. Just a quick look at some pics on the internet shows that the radiator set ups are different. If all the sensors are in the right place you should be good. Biggest thing Id think will be the intake system and throttle body since you have sensors in that and the bypass for the IAC is there.

actually shouldnt the 99 5.4 have pi heads n intake? and yes i figure the obvious comparisons. just wanted some experienced info as my old 5.4 is completely disassembled and its been about 6 months since i took it down so i dont remember.

 

[tcwaltz]

Yeah I think you are right. PI's started in 99. And there is a PI cast into those heads so you can confirm it.

Any time your swapping motors from different vehicles, theirs always going to be something different. I swapped a 1976 Datsun 280z motor for a customer years back, with a 50k motor from Japan. Nothing was the same but the block and head. I had to transfer literally everything off the old engine to the new one. If it was me, and I was doing swap, I'd transfer any old parts to the new that look different, or you think might cause an issue,so your not out here on the forum, trying to figure out why it's not running right. Just my 2 cents from an old man, that's r&r'd my share of motors. Keep us posted how it runs after your all done.

did you start reassembly yet

Head F.Y.I.

1999-’01 SOHC "Power Improved" Heads The "power improved heads" with the square intake ports were introduced in ’99. They had bigger intake valves, different springs and a heart-shaped chamber with a modified swirl-fin behind the intake valves. They’re all XL3E castings.

NOTE:
The "PI" heads weren’t used on everything in ’99, so be sure to you actually look at the intake ports.

Block F.Y.I.

1997-’01 The original block for the SOHC was a F75E-AC/AF casting that’s easily identified by the "X" gussets just above the pan rail on both sides of the block. The 5.4L still looks like the 4.6L Windsor with the dowel pins for the main caps, but the deck is about .350˝ taller to accommodate the longer stroke. The DOHC motor came with a F75E-AG casting that’s identical to the F75E-AC/AF block except that there’s one hole on the driver’s side not drilled, but it can be used for a SOHC application as long as this missing hole is drilled.

Juan, you really know your engines. Are you a a machinist? Or a mechanic for Ford? Pretty impressive cred's

Thanks 1955moose, but no none of the above just been working and restoring personal, family and friends cars for 30 years. Went to ITT Tech for mechanics never finished they taught me basically what I already knew. Hate throwing money at shops who guess there way through a repair and charge over $100 an hour when I can do that for zip. I did this a swap back in the summer / fall of 2015. If you got the time and the funds, I swapped out everything with replacements even changed out some of the bolts with some stainless steel, and chrome ones. Repainted the fire wall and any parts that were black. Had time to kill waiting on one motor mount. The wrong one kept getting shipped three times. The job was ported here on the forum.

 

[1955moose]

It's funny how many of the knowledgeable techs I read on this forum, are a in a totally different line of work. Well good to have your talent on the forum, Moose.

sorry guys, been busy with other trucks n motors, no i have not started the full swap yet, just noticing litle things like intake is at a 45degreee angle as where the original intake is straight forward, the oil cooler and filter assembly is different, etc. hopefully can get back to it after these next few overly hated days....and im not exact sure if new 99 motor is PI or not, just hoping. i needed a complete motor anyways lol.

 

[juan214]

No worry's just watch your post and ask away someone will answer. The heads should be PI's as I posted here on the forum 99+. Filter relocation is straight forward as long as the f-series motor filter is located in the front left (drivers) of the motor and not in the back. When you go to swap it out make sure your get the gasket from Ford. The one I got with my gasket kit kept leaking I R&Red it three times. All the after markets are the same one, there are also different gaskets so check the fit. Ford's is different and did not leak at all cost is about $15.00. Sell the your spare oil filter adapter on eBay it'll help with your costs.

 

[Nightmare99]

the f250 oil bracket is at the rear of the motor but connects to block at front, but eyballing it, it has the same bolt locations at front as the older cooler/remote filter setup..i do say finding gaskets has been interesting to say the least with swapping them lol....when i order headers, that should be fun as the manifolds are different too lol. ill get her whipped, and ill keep all updated, was going todo a tutorial with pics, but i noticed not a whole lot of ppl do this swap

 

[juan214]

Oh, I forgot the leak was anti freeze not oil. Got the block on a stand yet. This block is heavy as crap. Grab a pic of the adapter and post it.

There are a few differences between the 2 as far as the "options" go. The PCV system may be different depending on where the engine came from. The upper intake is different. PI engines came from the 99+ 5.4s and yours was a NPI setup. There is no problem making it fit as long as you have the correct intake. The rest of the stuff can be "tweeked" to fit. I'm not a fan of the PCV system on these rides. The 3 hoses on the pre-00 (I think) PCV system was changed to a 2 hose system for the later years. I cant remember all of them, but if you have the original add ons to the intake, they will swap over. I recommend doing exhaust at the same time...

That is correct the whole top end (intake up) on the Expy and F-series are different easy swap over though. If you tear it down top to bottom use care when pulling off the hose at the back of the motor behind the throttle body. It's a pain to get at, hard to come off. It is a hard rubber reducer type connector for the hose. It will be hard to pull off and will tear. If it tears or cracks and you don't check or see it the engine will not run due to the leak. If you tear it it's not available at the dealer start hitting junk yards. When I did mine I pulled the whole top end up in one shot. I pulled the fuel system, coil packs, throttle body, plenum, and intake manifold off in one shot. I have the entire assembly in my basement just have not listed the parts on eBay yet.
