It will be roughly the same hp limits as the 4.6. The limiters again being the connecting rods / pistons
+1
The 4.6 and 5.4 are essentially the exact same engine.
5.4 connecting rod is longer isnt it?
im using some forged I beams in place of the stock powered stuff dont need fully forged no FI or nitrous, wanted to know how strong stock rods are.
thats my plan i have a used set of ported pi's and gonna pick up some cams, HPS intake manifold, maybe 24# 30# injectors, and other supporting mods. i know it wont make power like any push rod h/c/i setup but its a daily driver and has some of that wow factor cause its not really that common like supercharged 4.6 is.

I like it, all i want is a mild street car and a fun project total ill speend maybe $2000
Got motor for $100 from friends salvage yard, already have the pi heads assembled (been in my garage for couple of years), gonna use 24# injectors off my MachUsed PI ported heads $ 500 to 800
New valve springs and misc
Cams $ 600
Timing components $ 500
HPS Intake $ 700
Injectors $ 180
Other parts $ 200
Tune $ 400
Junkyard engine $ 800
Total $3880 to 4180
I would do more research if I were you on pricing, I just did a quick search and this is what I cam up with minus all the time and labor.

heads an valve train-nothing
cams- 400 to 500 used

tune-200 an buy my friend dinner so 250
complete engine-100 85,xxx miles
and labor is free cause im doing it so lets say an even $2000
For the heads are they ported like you want, because they will cost about 500 to 800 to have a local shop port them. Or about $1200 on a trade in program.
For timing parts do you have the Romeo? Because the 5.4 is a Windsor block and they have pressed on timing gears they you can not use on an aftermarket cam. Plus you must degree your cams, and that requires some equipment.
A engine with 85,000 I would replace all the timing components with new items, a new oil pump as well as fresh gaskets all around. Cheap insurance to make sure you don't have to pull it out down the road.
I forgot to add that you will need to modify the exhaust in some fashion, Long tubes will not work and the H or X pipe needs to be widened.
Like I said, $3000 grand is the number I am sticking too. Good luck with the swap.
You're going to be very disappointed in your results.
