5.4 swap

liljojo4711 · July 7th, 2009, 02:14 AM

im going to be doing a 5.4l 2v swap sometime before the end of the year. is there a difference between the f150 and the expedition? either one better to go with? i will keep it n/a so not looking for the lighting or anything. can someone that has done this swap post a list of things u needed for the swap? is it better to go with an aftermarket intake such as the hps or are the adapter plates fine? anything i should look out for? what kind of numbers can the stock engine take? is there anything i should upgrade?

your going to want to change the top end. those engines are coming out of trucks that are designed for low end power and not high rpm power. your going to want the opposite

i plan on reusing my stock pi heads

you wont gain much hp, but you will see about 40 or 50 foot lbs torque

liljojo4711 · July 7th, 2009, 03:26 AM

right, thats y im doin it. hp will go up a bit with the pi heads but tq will shoot up. i dont need top speed, just lane switching

Then watch out for "Improper lane change" tickets.

I think what ke^in means is it really pisses cops off when you're diving in and out of lanes, which I assume is what you'll be doing if you want to use your added torque for lane switching

Bingo. They will give you a ticket quicker than shit for that. A lot of times they can charge you for racing even if you weren't. Seen it happen. And just because you are going the speed limit, doesn't mean that they can't get you if you keep going from lane to lane to lane.

And people who "race" like that need shot. That isn't racing. That's playing "Who's the biggest dumbass"

liljojo4711 · July 7th, 2009, 03:24 PM

it will be nice when passing big trucks and shit too.

im not going to do cams or anything, just new bearings, rods and pistons then im good to go correct. does it matter how many miles the engine has on it since im replacing some parts? will my odometer still read how many miles my 4.6 had or how does that work?

Ke^in · July 7th, 2009, 03:36 PM

Can you not pass big trucks and shit now? I can easily and my GT is stock. hell, I even kept up with a lightening.

Like I said, read other threads about 5.4 swaps. There is a shit load of information about it. Do tons of research. Obviously you should try to get the lowest mileage 5.4 you can, but i'm pretty sure your odometer would read how many miles your car (chassis) has on it, not how many the motor has. Might not be a bad idea to forge the internals as long as you're at it. I would do heads/cams also. Why not save up your money and then build it up all at once while it is out of your vehicle.

liljojo4711 · July 7th, 2009, 04:52 PM

i have read a lot and i have some specific questions. i might do heads and cams but that will push the budget from like $1500 to $4000...

liljojo4711 · July 7th, 2009, 05:44 PM

here is a list of what im pretty sure i need so far, please add, take away or make suggestions as far as brands and where do get them:

97-04 f150 or expedition block
HPS intake manifold
upgraded rods
upgraded pistons
upgraded bearings
all new gaskets
cobra brake system
upgraded fuel pump
ARP bolts
windage tray
timing cover
BBK 78mm intake combo
upgraded injectors

thanks for the help so far guys

your going to want stronger mounts as well.

BakerFX4 · July 7th, 2009, 06:21 PM

i got you a 5.4 block. bare and ready for you. And if you wanted to go 4v like a big boy then ive got ALOT of stuff you could get.

GreyWarrior07 · July 7th, 2009, 11:33 PM

i wonder how well those new trick flow heads would do on a 5.4 block with some nasty comp cams

isnt there a lot more involved when going from a 4.6 2v to a 5.4 4v... how much for the block? how many miles on it?
