Is 4.6L Superior to 5.4L

I figured I needed a full doner for an engine change. The hole trucks cheaper than a reman trans . I get a motor too w/120,000.
Prolly the cheapest way to go. I have a trailer already down there anyway.

I have everything! A friend of mine owns a salvage yard here in town. I told him what I was looking for, it took like 6 months, but he got in an 01 2x4 gator that had been t-boned and totaled at 28,000 miles. The hit was right between the front and back wheels on the passenger side. Mechanically, it was in great shape. The rear suspension was bent all to hell, the front wheel was ripped off, the frame was bent, all the airbags were deployed (except the ones in the sides of the seats which didn't deploy for some reason).
I got everything I thought I could need for the build, plus some parts that I could use on other projects. The complete motor, all the accessories (you know, ps pump, alternator (gators have a 200amp alt), ac compressor, etc. I got the 100 tranny (which I plan to upgrade and put it in my 2000 with the modded 4.6), drive-shaft, computer, wiring harness, gauge cluster, oil and tranny coolers (factory), big aluminum radiator, condenser coil, rear axle (9.75" LS 3.73, disk brakes of course) which is already in my 2000 F150 along with a new ring and pinion, heated and a/c'ed leather seats (all of them), the big front brakes, the rack and pinion variable assist steering setup along with all the hoses, steering column, the dash, and some other goodies. I basically stripped it.
You'll probably pee on yourself when you find out how much I paid for all this. I didn't pay a dime! Well, not for the parts anyway..... we worked out a deal where I built him 3 really nice new computers (one for his business, 2 for his house). So in total, it cost me about $2,200 for all that!
You should have done it! You don't need the computer or the wiring harness. Yours would work. You would need a tune, of course, but yours would work. The Gator short-block is just like the lightning. It has the steel crank, forged rods, forged pistons, etc. If nothing else, put the heads and intake on your 5.4.

oh well i do have a question...
this 5.4 i bought has nothing for accessories. no water pump for example. it has 1 pulley which i believe is the main/crank pulley. will my 97 4.6 water pump fit? that bad boy is brand new! stuff like that.

I'm uncomfortable about the computer thing, actually I really don't totally get it, duhh.. With that said, I don't want problems. That's why I figured I needed the whole truck - I would end up in the future rebuilding my motor or the doners motor at leisure/hobby. I want to stay away from electronic problems - to time consuming. I would like to feel confident every thing is compatible, I think it is. This is by far is the cheapest way for me to prepare for the future. The trucks sentimental now , so I'm keeping her.
The biggest prob I have with understanding the comps system is that a get different stories, which do you believe?
An 01's heads are different , pistons are different - that right there changes all parameters. The computers programming...Correct.
Haha , this is a question that usually don't get answered.
Like Klitch has a 97 computer - I 'm thinking he's going to have a hell of a time getting it to run right with his stock computer.
Maybe it's just a tune that will be needed.

Thing is , you might not have the all the wires needed sprouting from the 97 comp . 97 is year one of this motor , they kept adding crap over the years.
JMC would be the guy to talk to about it. I believe he succesfully did this.

Here are a few items i found: the knock sensor on the 5.4 had only two wires so i just clipped the connector and spliced it back. The oil sending unit wire did no no need to be lengthened, it fit perfectly. The wiring harness was so tight on the passenger side that i had to extend the a/c clutch connector. my 4.6 was a windsor so the flexplate fit right. If you have a romeo motor, it will have 6 bolts and you will have to get a new(to you) flexplate and 8 new bolts(or maybe just 2).Serp belt fit perfect. Made coil bracket for pass side out of metal strap. no problems. Exhaust manifold on the 5.4 was TWICE the width out from the surface of the head, so i wound up having to take the steering box off to remove the shaft to get clearance, about ten minutes extra work. I left the p/s presure hose on the pump, pulled the motor with p/s pump on it, then put the pump and hose on the 5.4. one thing i would have done different was pulled the trans dipstick and drained some fluid, becasue the passenger side manifold studs hung on the pipe and made it a little tough to get it in and i didn't see that it was hung.(dummy me!). One other word of advice, test your injectors if you are using the ones on a donor motor before you put intake back on( you do need to remove the intake for the swap inand out, at least thats the only way i know to do it). When i started it, the #6 injector was bad, luckily the 4.6 uses the same injectors, easy swap. Took it to the exhaust place, had down pipes fabbed up, uploade TROYER tunes, voila! now it breaks the tires loose easy!
brew, easiest way to identify the trans?

That's great!! These are just questions I have because I'm going to be doing the same thing down the road..

Theres two ways first , inside your drivers door - bottom of the tag it will give you a letter code.
E = E40D
U = 4R70w
Count your pan bolts - if you have 20 = E4OD 14= 4R70w
