f155
which transmission did you use?
do you have a wrecked mustang if not where are going to get all the mustang parts?
the mustang fox platform uses a oil pan than goes aroung a cross member did it work o.k in the f150?
f155, i own 3 vehicle and they all run. say what you want but a engine swap like you are attempting will eat 99% of the peoples lunch. it requires welding and fabrication skills, probably $1000 worth of tools, and a very well rounded mechininc with experience in a/c, powerstering, wiring as well as being a great trouble shooter. in my opion the wiring will be the stumbling block. this is not a project that is incredibally easy that takes a little bit of knowledge.
if you get a chance, keep a running total of the time you spend and the expense, post some picture.

 

any luck with the fuel lines?

 

I have the same truck with a 5-speed, and was considering doing the same thing with it as soon as I pay it off. Like Dave had mentioned though, the only thing making me nervous, is the wiring. Post some pics when you finish, and let us know how it went.

 

it has been a month, how is it going?

 

one of 3 things has happened

1. he never pulled the motor in the first place

2. he pulled the motor and has had a non-running 60k mile truck sitting in his driveway

3. that 225 h.p. motor runs so good he hasent had time to post here.

i vote for number 1

 

man, im dying to know how its going. f155, where are you?

 

4. He built a 400 HP stroker out of the 302 and is out looking for Lightnings to munch on.

5. He didn't find any Lightnings, but the stroker munched on his stock tranny.


Overall this wouldn't be a bad swap other than the tranny control concerns. The 5.0 has about the same numbers as the 4.6 stock, but with such a huge and cheap aftermarket, the 5.0 is easy to build on.

 

well it looks like he's stopped responding, but as long as the motor bolts up he could just go with a carb and then he wouldnt really need any wiring at all (except maybe an msd box). his check engine light would never go off, but everything else should work ok (except maybe the a/c).

a friend of mine did this in an 89 chevy, went from an efi 305 to a carbed 355 with about 400 hp. its real fast for a long bed ext-cab (he has a 5-speed, otherwise i dont think it would work because the motor is quite a screamer). everything but the a/c works; the check engine light never goes off though. he rigged the a/c to sorta work by installing a toggle switch that goes directly to the compressor, but his compressor was reman and we think thats why it dosent work so well (its also been over 100° here for the last 2 months).

he used the stock radiator, but it overheated at first, so he got an aluminum nascar-style water pump that has solved the problem.... its funny though because the thing goes up to full operating temp in _literally_ 10 seconds, even if it has been sitting overnight. then it just sits perfectly at 190° and dosent move a bit, no matter how hard he drives it or how hot it is.

anyway, if you're still there f155, let us know how its gone... ive thought about doing this too after i have a few hundred thousand miles on my truck and after i have some more money.

 

boy that sounds like a great truck especially the toggle switch for the kinda working a/c

the 305 to a 350 is about as simple as simple gets. same outside dimmensions, motor mounts, water pump..,. A 350 and a 305 a basically the same motor, different bore. while not 400 h.p. a t.b.i. 350 with a good set of heads and an emision legal cam could make 325 h.p. and pass emmsion testing all day long.

remember this guy isnt taking about a swap in a 11 year old high milege truck, he is talking about 4 year old 60k mile truck.

better pack more than a 400 h.p. 302 if you want to munch lightnings, while you have 20 more h.p. there is no way in h$ll you will make the torque.

 

Whew F155Ford,

Awesome, I am wainting to hear his response, as well.. I just bought a new 302 HO from ford and was going to put it in a mustang.. But if your engine swap works.. Let me know i will dump it in my F150. My 302 HO is at 345HP stock, naturally aspriated. I am going to to put a blower with a 200 HP nitro shot.. If that cant keep up with lightnings.. I give up!! WEll keep us informed..

 

his truck is pretty fast for what it is, it runs high 14's, which dosent sound to fast, but when you consider that the thing weighs aroudn 5500 lbs its not to shabby.

its got your basic stuff, like edelbrock heads and intake, 720 4bbl carb, straight duals (cats and glasspacks - by law the shop that put the exhaust on had to put cats on since it had them originally), msd, 4.10 gears, heddman headers, and some other minor stuff. the worst (and best) thing about it is the cam, it lopes pretty good and idles at around 1800; it makes it really hard to drive around town, but when you get over 4500 rpm or so the secondaries open up and the thing screams and kicks you in the butt. its worse than the vtec opening up on a honda... the motor is definatley not a truck motor!

i wouldnt recommend doing this unless you know what you're getting into, his truck really can't tow anything, he has to slip his clutch like crazy because even a normal start requires launching at around 2500 rpm, and its really hard to put the power to the pavement in a truck with no weight over the rear tires (he doenst have limited slip, though). also he has to be going at least 75 to use overdrive, because the motor really needs to be turing at over 3000 rpm to move the beast at all. also, he gets around 10 or 11 mpg in the city, and he has to use premium....

pretty much the truck was intended to be a daily driver, but it really cant be and he recently bought an s-10 and retired the big truck to a funmobile. but it is fun! there's nothing like smoking a civic Si with a long bed extended cab '89 pickup!

 

RTZ, if you buy a $3300 engine another 3500 for a blower, another 500 for nitrous plus probably another 1500 for intake and acess. thats $8800 not counting any labor, I imagine it would beat a lightning.

do you already have the mustang or did you just buy the motor?

 

Any word yet on how tha swap is coming???? i would love to do tha same for my truck (4.2l with 5speed)

keep us posted

 

I still consider this a complete waste of time. If the guy manages to pull it off, more power to him. But ehh... my question really becomes WHY>? LOL. I've always felt that if I wanted a fast truck, I wouldn't have bought a 4.2 in the first place. Anyhow, what's the 4.2 modular to (if anything)?

Also, whoever it was that mentioned the legality of this whole deal is absolutely right. It's VERY illegal to do this in many places. He could have swapped anything in that was orriginal equipment for that frame. Nice thing about having a 250 is that would have included the V-10...

Well, anyhow. The wiring might be a problem, the tranny might be a problem, the exhaust might be a problem, the whole thing might be illegal (don't get caught), and in the end it's not going to be much (if any) faster than my 4.6. I think I might have found my way to a junkyard lookin for a wrecked expy / 97+f150 with the 4.6 (or 5.4) in it, talked with the owner of the yard, gotten him to come down on the price somewhat for the motor, and by the way traded in your 'stang plant or sold it someplace. You'd have gotten SOMETHING for it.

Who knows? Maybe this is all fun for this guy?

 

BrotherDave,

Yeah i only bought a 302 HO Long Block Crate Motor from Ford.. It has no intake nor fuel injection.. Also a blower and nitrous must be purchased as well.. I already have the wiring harnes, a/c compressor, HT starter, radiator, alteratnor to finish it off.. Got it all from junked 93 mustang for $850.. I am currently talking with the junk yard manager about swapin my 4.6 for a 5.4 in an Expedition that has been totalled and only has 33,000 miles on it. But he is kinda hestitating because he doesnt know if he can resale my motor.. Anyway i havent decided yet.. Dammm too many options..
