I just bought a 1999 f150 back from my dad for $1800 and it's body is in great shape, but it's a v6 with CAI and flowmaster catback... Engine and trans are tired 250000 miles! Leaves much to be desired. I'd like to be able to tow with it, because I take my mustang to the track.

I know that the 4r70w is the wrong bolt pattern bit could swap for one with a 4.6-5.0 pattern.
Other concerns include
-factory fuel pump most likely adequate, could replace one from a 5.4 truck?
-will my factory factory trans control module still work with the 5.0 wiring?
-will a factory 4r70w hold the power of a stock coyote?
-late model restoration says the swap kit requires return style fuel system. Will my stock one work?
-as far as size/fitment everything should work.
-any issues with a 5.0 flexplate to 4r70w or starter issues
-exhaust- I would like to know if there are any long tube headers that would be a close fit. If not the stock manifolds should work

Any help with any of this would be greatly appreciated. I'm hoping this would be just as fast if not faster than a lightning, since this f150 is a reg cab step side with a few exterior mods.
Anyone know of any good threads that deal with 5.0 swaps?

 

Are you talking old 5L or new 5L ?

 

The 5.0 coyote is considered a modular engine same as a 4.6 or a 5.4. In order to do a swap like that you would really need a whole doner truck to get everything seeing how its a 4.2. if you had the modular engine you could just get the 5.0-c and the kit from ford to make it work. I think its to much hassle.

 

I can get a 4.6 4r70w trans for cheap, I can't remember if the new 5.0 and 4.6 have similar motor mounts. Either way I can find the mod motor parts I need or buy a wrecked donor truck. Out here there come pretty cheap these days.

 

The 4.6 and the 5.0 share bell bolt patterns and mount bolt locations. Its possible. Just kind of a big hassle. Ford does sell a kit for conversion so it can be done..

 

Do a V10 Swap!!!

 

i agree with that guy i would do the v10 swap if i were doing something like this

 

Thanks for the motor mount tip, gonna make things easier. I'm not worried about the hassle. I'd rather swap in a motor with double the power of the 4.2 that has the same economy. I could put a rebuilt engine and trans in this tired pickup but I'd still be forking out $5000 for that might as well spend about $2000 more for a 5.0 DOHC.

I'm sure a v10 swap would be much more complicated than a 5.0 and the fact that ford racing also sells the stand alone engine management system would make things much easier IMO

 

Ok after some research
crate 5.0- $6000 at late model restoration
Control harness-$1200
S&R power steering and alt bracket $500 (my stock power steering and A/C should work)
4.6 bolt pattern 4r70w trans locally sourced $300-$500 (do the J-mods myself)
Bauminator trans control harness $400
Walbro fuel pump and regulator (55 psi) and adapters $400
Motor mounts from wrecker $50
5.0 flex plate $250 late model restoration

It's seems the only REAL fab work is to modify the trans/fuel system/ and reroute the A/C lines to the passenger side. Is there anything else that I'm overlooking?

 

I also will be contverting to dual electric rad fans before swap along with a 20000 gvw trans cooler to help the trans.

 

this looks promising


-1 to the V10 swap. too heavy for a LD truck.

 

THANK YOU!!!! I've been on 3 other forums and you're the first that has actually shown enthusiasm for a project like this. I've been following the coyote swaps in the fox bodies and they have some major modifications beyond what I'd have to do. Some have to massage the shock towers and get a Crossmember from a 96-04 mustang and convert to manual brakes or hydraboost system. Those additional mods are beyond my interest.

For the past week I've been researching this and it does look promising. So thanks!

 

I will also be doing an engine swap!! I have the 4.2 and I want the new 5.0 with a KB supercharger on top. It's gonna be expensive but I'll have around $30,000 to play with when I come back from deployment and I'm not married and no kids so I can spend my $$ on my truck

 

I used to serve too but I was in the Canadian forces. I've dine a few tours but I'm out now. Good luck and come back safe.

As for your supercharger choice, I suggest you look at the edelbrock eforce. I have one on my 08 mustang gt and couldn't be happier, around 450 rwhp and can still get 27-29 mpg on the highway.

 

if I had 30 grand i'd just go down to the ford dealer and get me a new truck with a 5.0 already in it. But then again I spent enough on my old mustang to buy a new GT so who I to say..
