New Engine Time - Upgrading/More Power/Something else? Recs needed
So my 2002 F150 just turned 440,000 miles on her original transmission and motor. The transmission has some oddities and is about in need of a rebuild. The motor runs fine and makes no weird noises aside from some ticks and knocks. As long as I put a few quarts of oil in it every couple thousand miles, it runs like a champ.
However, her time is limited and because the body, paint, and interior are in good shape, I'm going to be rebuilding. I want to upgrade the motor to pick up a fair bit more power. I briefly looked at a 7.3 godzilla swap, but I don't think that is physically possible. Does someone make stock plus motors for this truck? What can I do on rebuild, or with a workable crate motor that will mate up to the stock transmission but give me a little more get up and go? It's been a great motor, but its underpowered by todays standards.
As an example, I had to rebuild my 6.0 Diesel, and I called Kill Devil and they build a nice custom engine that has noticeably more power than the original.

Tritons weren’t a great power upgrading platform.
Maybe a Navigator DOHC 5.4 swap can be had. Not sure the nitty gritty of that swap, but that’s an instant 40 horsepower shot right there.
Comp cams has this:

You’ll likely need tuning to run optimally, though.

It has a 2 valve 5.4L Triton. Original transmission and engine. It's been a good truck. The only repairs Ive made outside of maintenance items are replacing the intake, and two leaking AC hoses over it's life.

Wow, no cam chain replacements?
Maybe just re-ring the current engine, re-cam-chain and guide it, and keep driving . . . ?
I'd guess that a Godzilla swap might fit. It would take some engineering though, for mounts and electronics. Godzilla is an OHV engine and the 5.4 is OHC, so I bet they're close enough in size that Godzilla would fit without many shoehorns.
