I just recently came across a 5.4 2v at a price i couldnt turn down. I have seen numerous people doing the 5.4 swap in the newer models, but not many in older fox bodies. I have talked to a few people about it, and they say that it can be done and has been done before. So i decided to go for it, and do a 5.4 swap in my 1990 lx. The only problems that i am hearing about is how much harder it is to get the same amount of power out of the 5.4 2v as it would be to get it out of the 4v. And since the 4v can only be found in the lincoln navigator and blackwoods, the price is outrageous. What can i do to to help with the power in my 2v. Any suggestions on cams, intakes, etc.

go to a junk yard and buy a set of heads off of a lincoln mark 8. its the B head same head as on the 96-98 cobra. Can prob get them for 100 bucks tops well down here you can, buy the needed timing chain stuff and a cobra intake and you have a hell of a motor thats just itching for boost

[86er]

when my 351 pops or if someone wants to buy it, im gonna go 5.4 4v rout with a nice turbo hanging off it

[OneBadNotch]

Yea, i wish i had the money to just buy a 4v, but i cant seem to come up with it right now. But down the road i was thinking about installing a lysholm 1.6 twinscrew on it. But i still think i might come up a little short on horsepower. Im shooting for about 650-700. Any other suggestions?

Pushrods engines are so much cheaper to make faster..

ok so you can swap 2v and 4v heads.....are all 4.6 blocks the same......can u just swap 2v heads with 4v heads on say a 2000 gt....i ges if you swapped heads you would have to swap the intake though....are the 5.4 and 4.6 blocks the same

5.4 and 4.6 blocks are different. Heads *may* interchange, but I'm almost positive the intake manifold is unique to the 5.4.

5.4s are difficult to get power from at anything resembling reasonable amounts of money, and I'd argue that you can get more from a stock-stroke 5.0 than you'll ever see out of a 2v 5.4L. There's just not the aftermarket for those motors like there is for the 5.0 or 4.6.

Props to you for doing it, but if your goal is making power, I think you're gonna be disappointed.

You'd probably get a lot more information posting this in the modular section.

if you're doing it because you're bored, or want something weird, go for it...

if you want a race car, don't waste the time.

factory 4v heads flow crazy, dont even need to port them. A set of cams albeit pricey are a nice investment, along with longtubes.

The heads are all the same 5.4 or 4.6, you can put any 2v or 4v to any motor.

Intakes are dif, just like a 302 to 351w. Just wider. They make a few intakes that are perf oriented. Just depends on how crazy you want.

The thing with mod motors, you can use factory ford stuff and build a short block that will handle 1200hp.

Buddy has a 5.4 4v with a 76mm makin 11xx on stock heads, cam and internals.

[86er]

stock parts and a turbo kit and you can plush 1000hp all day long

ford even has 83lb/hr injectors now in mod motors.

dont see a stock parted pushrod doing that.

The parts arent that bad, is all where you go to buy them

go talk to Al Pappito and ask him about his all motor 5.4 thats puttin down almost 500 at the wheels.
using all stock parts, except cams I believe

You should do more searching before you speak of something you know nothing of.

the intake manifold and internals are the only real parts that are different.

thats only because of the longer stroke of the crank and longer rods.

Remember that I said 2v 5.4L. Al Papitto is using a 4v motor.

Here's an excerpt talking about Al's car, the whole article can be found here: 1997 Cobra Al Papitto - 5.0 Mustang & Super Fords Magazine

Al began cooking up a combination. He started by having the block bored 0.020 over and filling it with the stock forged crank, Manley billet rods, and custom JE pistons. American Cylinder Head handled the machine work, while Al sourced Pro Power for the rods and pistons.

With the bottom end transformed, Al set his sights on the Four-Valve heads-the most modified part of the engine. His motorcycle background made the modifications come easy. "The Four-Valve's tumble-port design looks a lot like a Suzuki Hayabusa head," he says.

Cope Racing Engines' (which built and prepared the engines for the late Dave Schultz's three-time championship Suzuki and Al's two-time championship Suzuki) Buddy Ordway spent many hours on the valve seats and ports, while Al was busy making the valves from Ferrea blanks initially designed for Kawasaki engines. Kawasaki Z1 valvesprings and titanium retainers, along with Crane Cams' reground cams, complete the valvetrain.

Though the heads were easy, the difficult part came in the intake department. After much research, Al decided to make his own lower intake, which took him a month and a $3,000 investment. A Hamilton Clarke intake cover tops it off.

Bolding done by me. So remind me what's stock in this motor again? Block and crank?

power from a 2v 5.4 is not hard at all


id take a PI 5.4 2v and run it all day long against a bolt on 5.0.

I dont know too many intake, headers and exhaust 5.0's are runnin in the 12's.

I know of at least 15 99+gt's with just those mods on a PI 5.4 running 12.70's and quicker in a car thats heavier

What's a PI 5.4?

Do you mean a 5.4L that someone swapped 4.6L PI heads on?

[86er]

99 and up like the 4.6

Ah, k, didn't know the 5.4 got PI heads the same year as the Mustang.
