Hello!

I do a lot of reading on here, and have a couple questions that I can't find solid answers to (maybe I'm not searching the right words?).

I have a 2003 Expy 5.4L, and I'm wondering if rebuilding my current 5.4L Triton would be worth the time, or if buying a Lincoln Navi 5.4L engine and doing a swap would bebetter? I hear a lot of good things about the Navi engine, and very few about the Triton...

I'm also looking to rebuild the trans, or swap if needed...

Can someone point me in the right direction?

Thank you!

I will be doing all the work myself :) Just want to get something solid I can put a turbo or supercharger on in a couple years and not worry about it blowing up.

The Lincoln 5.4L InTech looks pretty good with a 40hp increase over the Triton that I currently have, and sounds like it'll bolt in without too many mods. Does this sound right?

I remember reading a post on here where someone rebuilt the tranny and added some clutch packs to each gear to increase hold? I've been looking for two days and can't find it...

I appreciate the information a lot! I'm not a mechanic, just mechanically inclined.

Yes, a crate engine would be more practical for you. It would serve you well for a longer period of time.

The 5.4l short block engines both should be the same the external parts would be different. Double check with dealer for interchangeability.

Thank you juan214 for those part numbers! Very helpful.

I'm doing more homework and probably starting this next spring.

Is it easier to pull the engine and transmission out at the same time? And is there a write up for that procedure?

Engine is a PIA by itself. It barely gets out by itself we are talking fractions of an inch of play. To pull both at the same time you'll probably will need to pull the front of the truck. I have a engine swap on here under "Expy Knock". Check youtube for some videos.


Good luck

Hi Wolf, the 5.4 tritons seem to be an either or. Bulletproof or issue plagued I happen to be in the lucky category with 266k and runs great. I bring this up has a judgment call has to the miles on your vehicle and which of the two categories they fit into. Even with my good motor I am most likely going with a crate motor that I will most likely put a supercharger on.

Reason is that these engines have built in flaws that need to be remanufactured to remedy and with so many horror stories about block integrity I personally do not want to take the chance, secondly I would go remanufactured trans to remedy the baked in issue, Plus when rebuilding trans no one replaces all components so a reman would.

If I would to rebuild I would have my block checked and Scanned for integrity and rework the needed areas so it would probably cost about the same as crate from my research.

Best of luck and just my opinion

Great advice! I'll be looking into the crate motors, and the more I read and opinions roll in, the more a reman transmission sounds a lot better.

I should clarify that I'm doing away with the triton in the expy, it'll be better to turn it in for a core than rebuilding it.

I appreciate all the replies!

I think this info is correct, only thing is if you go from Triton to InTech either the PCM may need to be flashed or replaced and married to the new engine do some good research. Hope someone can chime in on this.

2-V 5.4

Ford installed its first 16-valve 5.4L V-8 into the 1997 Ford F-150 pickup and marketed it as a Triton V-8. It featured a 3.55-inch bore and 4.16-inch stroke. The longer stroke increased the deck height of the engine over the 4.6-liter version. It featured a cast-iron block, aluminum heads and a multi-port electronic fuel injection system. The valve lifters were a hydraulic lash adjuster design with roller follower. Other features included a forged steel crankshaft and fracture-split powder metal connecting rods. A 9-to-1 compression ratio helped it develop 255 horsepower and 350 foot-pounds of torque. Some versions developed up to 260 horsepower while the performance Ford SVT Lightning F-150 came with a supercharger and a rated horsepower of 380.
  • 2003–2004 5.4 Liter (330 cu in) 16-valve SOHC Triton V-8 gasoline 260 hp (194 kW) 350 lb·ft (475 N·m)
3-V 5.4
Ford introduced the 24-valve version in 2002 to power sedans but two years later offered it in the F-Series trucks. It featured variable camshaft timing and more power and torque than the two-valve models. The 24-valve 5.4L provided lower friction than the two-valve versions and a single overhead cam with roller follower. The cylinder heads were aluminum alloy. It delivered 300 horsepower and 365 foot-pounds of torque partly due to a 9.8-to-1 compression ratio. Ultimately, output rose to 320 horsepower.
  • 2006–2008 5.4 Liter (331 cu in) 24-valve SOHC VCT Triton V-8 gasoline 300 hp (224 kW) 365 lb·ft (495 N·m)
  • 2009–2014 5.4 Liter (331 cu in) 24-valve SOHC VCT Triton V-8 gasoline/E85 ethanol 310 hp (231 kW) 365 lb·ft (495 N·m)
4-V 5.4
Ford sold the 32-valve 5.4-liter as an InTech V-8. It was a new version of the original two-valve 5.4 with a dual overhead cam. Ford favored the InTech in its trucks, performance cars, the Lincoln Navigator and the Ford Falcon in Australia. But the 32-valve 5.4L powering the SVT Cobra performance cars differed significantly from the truck versions. It came with high-flow cylinder heads, a higher lift cam and a 9.6-to-1 compression ratio to develop 385 horsepower and 385 foot-pounds of torque. The Shelby GT500’s 5.4 featured a Roots-type supercharger with an air-to-liquid intercooler to generate up to 550 horsepower and 500 foot-pounds of torque. In contrast, the Lincoln Navigator’s 5.4 generated 300 horsepower and 355 foot-pounds of torque.
  • 1999–2004 5.4 Liter(330 cu in) 32 Valve DOHC InTeck V-8 gasoline 300 hp (224 kW) 355 lb·ft (481 N·m)

Additional consideration the Navigator Transmission comes in 4 or 6 speeds
