Tow vehicle getting a new heart
 
I decided to bight the bullet and give my beloved 1999 Expedition a heart transplant. I located a brand new, never installed or fired 2001 Ford 5.4L Supercharged Lightning crate engine to replace my standand 5.4L powerplant. The old engine was leaking at the head gaskets into the valley and on to the exhaust manifolds making a pleasant smell inside the cabin.

The new engine comes standard with 380hp, 430 ft-lb torque. The stock blower has already been sent off for porting and polishing and will also be underdriven to create 15 lbs of boost (stock is 8 lbs.). We are also puttinig a cold air intake, a special tune and equal-length headers, high flow cats and a new stainless performance exhaust. Lastly, the transmission and transfer case are getting beef up to take the added horsehpower and torque.

I should be done in a month and has already been in the shop from a month. Can't wait to get it back. I'll post pictures as the work progresses.

I really like the sound of this.

Put in a larger fuel tank, that's a 6mpg proposition

curious as to why you went the engine replacement route instead of buying a new truck... ecoboosts almost match those specs and will have to provide alot better gas mileage.

Who's doing the ECM work for you?

The mpgs will improve from the horse power alone. That's as long as you baby it. If you floor it everywhere then it won't be as good.

Sounds like you're making the right mods, good luck and hope to see pics and sound clips.

You will have all your torque immediately with that roots blower. That's going to be fun! You should have ditched the stock eaton blower and gone with something along the lines of whipple or Kenne Bell with even more displacement. :D

Am I the only person here that thinks this is a complete waste of money? Unless you got the engine for free and are a mechanic, why would you spend that kind of money on a 14 year old vehicle? Maybe I am missing something here. Don't get me wrong, I love horsepower and have a classic car, but just can't understand the justification. Please fill me in.

Thought about the Whipple or Kenne Bell but would have had to build the bottom end as the rods are still the weak link - even in the SVT Lightning engines. Tha will be round 2.
