New Engine... Upgradr
It appears that my 2008 f150 lariat (5.4) needs a new engine. I’m thinking that since it needs a new engine, maybe I should upgrade it to something better/bigger.
Are there any swaps on the easier side, more bolt in, plug and play style?
I use this truck for towing a race car on an open trailer and a 20ft camper.

There's no easy replacement for the 5.4, if you want more power, put a reman engine in and supercharge it. Chenging to a different engine would require a significant investment of time and money, as the replacement would need a new ECU, but the ECU also works with the truck itself for options, etc.
Going beyond that option, might as well just buy a new truck.

The reason you're kind of stuck with the 5.4 is because anything else really isn't practical.

I wonder if a 4.6 2V harness could be made to work with the 5.4 2V Supercharged Lightning/Harley Engine...
Did you ever put a good aftermarket tune in the 5.4? The PCM is programmed for a pretty slow opening rate.With a good aftermarket tune (not the standard SCT canned tune) it goes from barely squealing the tires to blowing the tires clean off with a stab of throttle. People think it's slow when in reality the TB isn't open all the way yet.
