Engine swap 4.6 to5.4

I didn't think it would be that expensive to do. Where would all the cost be?

A lot of the cost is in the motor, the prices I've found for a wrecked Gen. 2 lightning ran from $4,000-$6,000 depending on the miliage. For $6,000 one could build a 4.6 with the same HP and torque as a lightning with less weight upfront. But if one just wanted to find a 5.4 out of a truck or SUV than the cost would be a little less than a lightning, but you would still have to worry about the added weight, and for a street car it just doesn't add up. I mean you can buy a complete new 01 cobra longblock for $5,000 and have almost the same HP and torque as a 5.4 NA.

I wasn't think a Lightning motor. I was just thinking a regular 5.4, those motors are cheap.

the lightning motor is so tall with the blower that you would have to cut a huge hole in the hood for clearance


with a 5.4 2v motor they make everything to swap them out and even have adapters so you can run the stock intake setup from your 4.6

plus they have a shitload more torque than a 4.6...id swap it out

I kind of figured that's what you were talking about.

The hood clearance for a lightning motor w/ blower was also an issue I did'nt want to deal with. What are some names of companies that make the kits to do a 5.4 swap?
and whats the weight differance btween a 4.6 2v & a 5.4 2v?

let me see if i can find the magazine with the companies name that makes the intake adapters and such....sucks that i just sold a complete 5.4 about a month ago

Yea that does suck, I've been going back and forth about doing a 5.4 swap, about the time I think it's a good idea I talk myself out of it and start looking in other directions. I read an article in the June issue MM&FF about 5.4 swap and he made it sound easy. Even through he fabed his own intake adapter.

it is an easy swap...everything changes over with the exception of the intake adapters.


if i had a mud motor car id do the swap already just for the torque gain and then strap a kit on that bitch and ride it like a two dollar hooker
