Everthying else from the newer 99+ engine will work. You will have to drill out the header flange holes in your y-pipe because the PI manifold have larger studs along with a slightly wider bolt pattern. You also have to remove the y-pipe hanger at the back of the transmission to allow the y-pipe to slide .5" forward.
Tractive55LS, - don't remove anything, plumb your ECT as I posted ealier....keep all that kind of 98 stuff.

On the exhaust I know there is a difference. I actually measured them when I did the my pi swap. The exhaust ports are larger on the manifold for inlet and exhaust.. Npw the ECT/CHT i get them confused. Because I eliminated it in turning.. I just run off the one sensor under the intake.

Wow alot of bad information. To use the PI 5.4 in a NPI equipped truck you only need to reuse the the throttle body elbow. Everthying else from the newer 99+ engine will work. You will have to drill out the header flange holes in your y-pipe because the PI manifold have larger studs along with a slightly wider bolt pattern. You also have to remove the y-pipe hanger at the back of the transmission to allow the y-pipe to slide .5" forward. Dont worry about the CHT because in 99+ they stopped using the CHT. Just have it removed in a program.
The 98' plastic elbow will not work, why? I have both the OE 98' and 03' throttle bodies to choose from? What do I use?
I have SS shorty headers to install, no more darn cast iron warping, rusted out exhaust manifolds to deal with.
I'm fairly sure I'll be buying new Y-Pipes/cat assemblies, will I need them to fit 98', or 03' F150 when ordering? Was thinking Flowmaster, both about $600.00 L&R.
There's no more cylinder head temp sensor or threaded hole for one?

Bad info, your tellin me lol.. -It would easier, but that's about it.
No NonPI and PI are identical at the exhaust port side...just have the OP confirm that one for yuh.
Since when ? Oh 99...NOPE wrong again lol. In 99 they illiminated the ECT sensor. So, everything thing then was routed to the CHT sensor which they used 99-04.

I thought it was "EngineCoolantTemp" Sensor ?
Anyway,correct. The 98 5four has an ECT, -front upper intake closer to drivers side. The 98 also has CHT just below inside front drivers side head. You can see this if you look down into the block cavity in the general area.
The 03 doesn't have an ECT sensor. So you just purchase a brass T-fitting and integrate into the hose on the passenger-side of the engine. I have pics of that somewhere. I'll have to look for them. BTW, - clean that brass buld up well before installing.
Just so you know, - not all 03's have the updated plug chambers. In fact, I haven't seen one that has personally. But yea, I know Ford fixed that problem in 03. Looks like they wanted to clear their stock of 02 heads before using the upgrades in 03.

BTW- You'll be able to drive the truck just fine after the swap, - IF you keep the 98's electronics. If you don't, your dash instrumentation won't even work right, - nothing will lol. Anyway, yea. It'll drive fine without tuning it for heads or exhaust if you have headers. You should run a good intake with all that...the best. Like a Amsoil nano fiber filter..dry high flow element. But, make an appoint with a tuner and ask about price. Dyno time can be pricey, -unless you have your own tunage and datalog... yourself.

Your saying every 98' electronic F150 plug 'will' plug into the 03' injectors, COP's, TPS, knock sensor, coolant temps sensor etc....?

Maybe, but I don't think they're phased,- which is the only difference between resistance and impedance. both deal with the magnitude. You may be right, but that's news to me. I've run 3.8 Ford windstar injectors in the past and have been running 04 crown vic design III's since 08 in my 98. IMO a orange body 19lb injector is just that and the injector drivers control flow..software.
You will need to use the knock sensor from the 98. I used the 03 knock sensor but used the proper release tools and just changed the connector. Some of the vacuum port on the 03 arent used on the 97-98 elbow. The throttle bodies are the same if I recall. You can use either y-pipe setups for the 98 or the 03. the 98 only have 2 cats in most configurations where 03's have 4.
BTW- ALL 97-03's have 4 full catalytic converters on there v8 petrol trucks factory. No pre cats, - those don't exist for these trucks. That hasn't changed until 05 when they ran a single3 (they named it lol).
