I was the guy who started that intake mod and the gotts o2 mod and I believe that I am the only one to put a FACTORY 4r75e into the 97-03 body style truck as well.

You are correct on the HPS intake manifold. There was a guy on a local forum that had one and I went to take a look at it. There are issues with the HPS intake as well. You cannot use an HPS on an NVH block because of the ribbing in the valley. You must grind it off and take a lot of the integrity out of the block itself. I am not a fan of it at all. All the dyno results posted by HPS and independent people who have went from the adaptor plates to the HPS intake. I haven't seen anyone use the truck intake manifold other than myself. I haven't kept up on what was happening because I started the project nearly 2 years ago now. I really hope the adaptor plates work out for you.

Your converter should bolt onto the 5.4 flex plate. I believe all the trucks have the same size converter

 

for another $1800 you could install that partial setup...



and I hope you install all new o2 sensors

 

is right. thanks for bursting my bubble!!! and that dosnt even count in the cost of my trans that would blow apart.

so all i need is the 8 bolt flexplate (which is only 35 on rockauto)
cant wait to see how the higher stall TC works with the 5.4

im curious what the hp difference between the 4.6 manifold w/adapter plates v. 5.4 truck v. HPS intake actually is- or even just the 4.6 Adapters v. 5.4
if it made that big of a difference i think the stang guys would run the 5.4 and cut a bigger hole in the hood. Idk


new o2 s at least in the front sounds like a very good idea

 

Why are you dead set on using the 4.6 intake with adapter instead of the 5.4 intake? Not insulting you, just curious.

 

this way i dont have to source out a intake manifold and everything *should* bolt right up, NO modding. if i had a pre 04 4.6 to look at and compare to my 04 4.6 to make sure of the similiarities. i think this way is less chance of failure and sheer simplicity.... now im starting to double guess myself.
only time will tell.

so 123 engine has not sent me a conformation. Eli s mechanic was suppose to call me about the timing stuff. maybe i shouldnt have confused them with it.

 

I would think that the NBS 4.6 throttle body would just bolt right onto the 5.4 intake, or not.

 

I agree with your reasoning for the adapters



some of the lightning guys have been running some incredible times at the track with 'em

 

This is reassuring

apparently i missed the call last week from eli's mechanic.
motor has been shipped.

 

at least they got a cool logo- a ape with a mohawk

 

thinking about porting and polishing the inside flange to get better flow. some of the welds stick out

 

what happened to my poor plug????
thats one expensive plug!!!

 

not really part of the engine swap but here are the rims im putting on. kind of a whole transformation. still at the shop, somehow there balancing machine broke so the trucks spending the night.

i ll update with pics as soon as i get it back.


the old ones are for sale!

 

nice RED X's

in the process of getting the timing set...
can anyone confirm the if timing set for a 03 e250 van with 5.4l engine code L is the same as 03 f150 engine code L. ??????
on rockauto- an 03 f150 has one timing set for sale for 158.oo and 03 250 econoline has two, the same part number and another which is only 108. im hoping they are swappable. iordered the latter.

also have on the way 02 expedition 5.4l timing cover used ebay deal 60 shipped

everything is bought and paid for part wise- other then the dual exhaust im going to weld up
