i have a question, purist beware!
 

Well i got to thinking, i love the 1997-2002 f150's but i dont like their engine options. So i was wondering how hard it would be to swap in a 5.3 or 6.0 ls styled engine and transmission. Ive seen ls swaps on mustangs and a couple crown victorias which i think share the same mounting points so could i just use one of those swap mounts? What about transmission/fuel/wiring...or ac and all the other options? If this is possible it could very well be in my future...so any help is apreciated :)

LS swaps are pretty easy, but an easier swap is a Lightning 5.4L... it literally plugs up for the most part... the engine harness is different, you can use yours but an L harness has 2 air temp sensors... change that and put a 325 fuel pump in and its good to go! beware of the 4R70W though, they are good transmissions but the weight of a truck will kill it quick... Make sure its either built to handle the weight or put a 4R100 in if you decide to go with a L motor...

I dont have alot of knowledge on fords. Ive allways owned chevy's with the occasional dodge. The lightning engine would be an easy swap? What all would i have to do to swap it? Building up the 4R70W wouldnt be an option considering id build up the 5.4 and i dont think even a well built 4R70W could stand what my ends goal is so the 4R100 would more than likely be needed. So would i have to change the trans mount for that swap?

Well i did some searching and found out that is is a direct bolt in/plug and play engine it just needs to get tuned. But i still need to know about the 4R100 swap.

what goal are you wanting from the truck? have you already bought one? the Lightning engine is a very easy swap... the engine and trans will bolt right in, same mounts and all... if you find a truck with a 5.4L (if you don't already have one) then you can just buy a blower and mount on the existing engine and some already have a 4R100 transmission in them... however if you want big power you'll need to build the engine for boost... if you find one with a 4.6L you can buy a L motor and trans and repin the engine harness and find a transmission harness... then get a custom tune... the only other thing beside the harness is exhaust, a 4.6L is lower than a 5.4L obviously so the manifolds I believe will have to be changed... you'll have to check me on that...

Or could just swap in the navi DOHC 5.4. 300hp stock I think. Idk how hard the swap would be tho.
