what is the difference between a lightning and a regular 5.4l f150 as far as the engine(internal and external) is concerned.

and I know the lightning has a S/C I am just curious if the lightning has stronger internals or what because I was under the impression that all f150s were built with forged internals

 

Forged Steel Crank
Forged alloy connecting rods
forged pistons(compression ratio to 8.4:1)
The Blower. Water to Air Intercooler

Transmission: 4 speed out of the Power-stroke Diesel

Suspension and Steering
upper and lower A-arms
SVT coil springs
SVT gas-charged shock absorbers
31mm solid stabilizer bar.
Front-end ride height lowered half an inch
9.75-inch solid axle
3.55:1 limited-slip rear end.
SVT-tuned gas-charged shock absorbers
Rear:
SVT five-leaf spring system
SVT 23mm solid stabilizer bar
Rear ride lowered 2.0 inches
The staggered right rear shock

Brakes
F-250 Super Duty truck ( 4.0 mm thicker then F-150) front:12.1in twin-piston calipers. Rear 13.1 inches.

Rims and Tires
The cast five-spoke aluminum-alloy wheels 18 x 9.5 inches.
Tires: Eagle F1-GS 295/45ZR18

 

The only thing internally is the forged pistons and crank!

My stock 03 5.4 had a forged crank.

Lightning and regular 5.4 have the crappy rods in them.

ah I see the reason I am asking is because I want to do the whole 4.6 to 5.4 swap but from what I have been able to find I can get a regular 5.4l for about 400-800 and the lightning engine I cannot find it for less than 3000

So I was thinking about buying the regular 5.4l engine and then rebuild it with completly forged internals (buy a forged rotating kit) and then either do a twin turbo kit or a ken belle supercharger(but by the way it sounds the supercharger might be a easier option)

what do y'all think

 

wow

all 5.4's made between 97-01 had the forged crank. All 4v navigators had it. All lightnings/harleys got it as well. 02-04 2v's had a 50/50 shot of getting the forged crank or the cast one.

 

well I ran into a small problem I cannot for the life of me find a engine rotating kit for a 2003 f150 5.4l engine its like they only make rebuild kits for the 4.6l engine

so since the 2001 is the most recent that has the forged crank I might as well just get the 5.4l engine from that year.

 

The reason the L motor is so much more money is they are more in-demand and they are supercharged!

Here ya go,,,hope I didn't forget anyone.
Have fun shopping.

Man thanks alot for those sites I might have to go with team jdm for the engine rebuild kit, and then summit for the crank and then buy a gaskets set/head bolts from a different place and then try and figure out what else I will need to finish that off.

well time to go and find a 5.4l engine and if I can find it cheap enough then I will put the money saved towards a kenne belle supercharger.

 

yeah thanks alot for those sites phil

 

the '99-'00 Lightnings had the 3.55 rear gears, the '01-'04 Lightnings had 3.73 gears

 

^^^This is new info for me! How does a person KNOW if their engine has a forged crank? Where do I find it?

The third post has comparison pics, and they go on to show casting/forging numbers.
