Lightbulb Engine swap for a 1998 F-150 4.2L to a 5.0L

I've been wanting to do a engine swap for a while to get a some more rumble out of my f-150. I've got a 1986 lincoln (futher derby car) with a fuel injected 5.0L in it that i've thought about putting in my f-150. Anybody have any suggestions?

Mine would be don't bother, you can put a stock PI 5.4L in very easy compared to the 5.0L and it will have 260hp, the 5.0L stock won't have anything near that. With all the bolt on's you can think of you could push 300hp fairly easy with the 5.4L then stick a 50 shot of nitrous on it for a cheap performance fix.

For all the time and money a 5.0L would take you could tear into a 5.4L or even 4.6L and should be able to push 350hp N/A out of them with reworked heads and intake etc etc. Or you could just drop $4K on a low psi blower and be at 350hp easily.

Maybe he isnt going for lots of horsepower. Sounds like he has a motor sitting around that could be used instead of maybe spending so much cash on getting a 5.4! Keep in mind if you get a 5.4 you still have to buy a ton more stuff to get it to work in that truck, wiring computer etc.

It would be far cheaper to get the 5.4L to work than a 5.0L. Aside from a ECU reflash the 5.4L is more or less a bolt in, as close to one as you can get these days. You could run it off all the 4.6L wiring. It would be easier to go to a NPI because of some sensors the PI would have but really nothing major compared to trying to get a 302 to work.

the boy took a 4.2 out of an F150 and installed a 302. They used a distributor and carburetor to keep it simple. Had to make eneing mounts, etc. Biggest problem they had was it vibrated BAD when they got done. I did a little research and found the 4.2 is a balanced motor. The 302 he had was externally balanced with the flywheel and harmonic balancer. I had to pull the motor and remove the flywheel, machine it to match othe old counterweight flywheel and reassemble. Dont remember the full story, but the starter hole was too far over to use the 302 flywheel and they had to get one to bolt to the 302, aht would accept the 4.2 motors transmission and clutch, etc. LOTS OF WORK, but runs o.k. for past 6 months.

I got 4.6L in my head, forgot he had a 4.2L, there are some nice 4.2L turbo set-ups out there as well.

I've got all the sensors and everything else to convert over to the 5.0L, I was wondering about the transmission and the flywheel fitting right.

The lincoln is still road worthy except for a power steering leak.

What are the emissions laws in Tennessee? Here in California the swap you mentioned would not be legal for street use, as it would not pass our smog inspections.

They never have checked the emissions on any of the vehicles that I have ever owned before.

Yeah in my own opinion just buy another truck with at least the 4.6 or 5.4 and save the time money and headache just my 2 cents engine swaps in newer vehicles can be done but much more complicated cause of computer etc thats the easy way out unless you would really want to swap it

They only test in the metro areas like Nashville and Chattanooga. If he lives in a rural area he won't be tested.
