So if your blows up what do you do assume 5.4 2v?

Rebuild 4.6 or 5.4 2v
try make a 5.4 3v work
try make a lighting motor work 2v or 3v
try make V10 2v or 3v work
or total custom Diesel, turbos etc.....

the V10 interest me 3v 362HP and 457 torque ( if my numbers are right)
it's like a lighting but no premium gas ...
I may be wrong with the #'s

This has sorta been covered but you did change the options and conditions...lol.


If I had the money I would have twin turbos and built 5.4

Old video of Casey's 2002 twin turbo lightning. 5.4 2v with trick flow heads. Apparently they work really well with turbos.

Twin Turbo Lightning - YouTube


I have yet to see a 3v lightning but it has been done with 4v navigator heads so assume an adapter could be fabricated to mate with the lower intake.

Sell it for parts and find a Excursion with a 7.3 Turbo Diesel. ;-)


Of course, it might be fun to wedge a slightly modified 5.4 4v Shelby mill under the hood of the Expedition...

They were rated 300hp... same as the newer (vs the 32v 5.4) 3v motors. Many lightning owners have done the 4v heads plus turbo mod as well and they run very strong but Caseys I believe is the fastest street lightning. Runs 8.80's in the 1/4.

If you visit the lightning forums, there are many potent combinations that would work just as well in the expedition. Carrying a bit more weight though... :( But no turbo diesels... sorry.

If I could I might even wedge the old 429 I had, but I was thinking more everday use, towing.
Thats why the V10 is interesting, dosen't someone make a blower for it ?
I guess you could put a turbo on it. You can't beat the displacement

I think the 5.4 with 4v or tfs heads would trump the v10 in performance applications. The V10 is somewhat limited with performance mods basically due to the heads. It is great for low end torque though and where the displacement really shines. Stock vs stock it obviously holds the edge.

The 5.4 shares the same basic design as used in the mustangs, lightnings, etc... so there is much better aftermarket support.

I am sure a V10 could be made to put down some significant #'s but it would be more difficult due to the lack of support and likely involve some custom fabrication.

I just like the power the V10 makes with regular gas. but yeah mod wise you can't go wrong with a 5.4.
Although could I make the same power with a 5.4 2V with out going to premium gas ? Would heads and a cam do enough? they don't make intakes do they ?

I believe your best option on making more power with low octane fuel is displacement. Generally making more power with less displacement raises cylinder pressure requiring better fuel. Way oversimplified and leaving out many other factors of course.

Which would you rather do. Pay an extra 12% per gallon and get a 20% increase in fuel mileage or have a 20% loss in fuel mileage but save 12% per gallon. Hypothetically of course...

I will be selling my 74 Torino and the 460 build I started to get a 5.4 long block and start building it for the expedition. I will have LOTS of questions but I can't wait to get started!

I'm leaning toward a 5.0 coyote

5.0 coyote with a minimum of 4.10 gears, maybe 4.30's and higher stall converter to take advantage of the coyote's powerband would be nice.

Then add supercharger or turbo...

Toms89, if you are ok with it, I will be picking your brain clean here soon so I can get an idea of where to start.

Don't do it!

Of all the cars I've owned in my life, I miss my old Torino the most. If I could have one car back, that would be the one.

This is what she looked like. (not actually a pic of mine, but a twin in every detail I can see)

pic-41351.jpg

Even with a lowly 4v 351W, it was a fastest car I've ever owned too, up until I picked up the Bullitt in '08. 351 4v, C6, console shifter, 4.11 traction-lok. Passed everything on the road except a gas station, I think it was even worse in that regard than my Expedition is.

But boy, was it a fun ride. I miss it dearly.
