Engine Swapped Cars

Watching do you guys think about engine swaps into old Italian sportscars/supercars? Been wanting to restomod a detomaso pantera. I'm familiar with lsxs and wouldn't feel bad considering it was powered by an old ford anyway.

Got nothing against it if the original engine is fubar or a pita to restore, but kinda weird it's working fine and puts out reasonable power.

I've been considering purchasing a fox body Mustang and dropping a 2.3 EcoBoost in. Haven't seen many people do it yet, but it sounds like a cool project.

Are you from North America? Isnt the 2JZ-GTE way more practical to find parts for than a 1JZ-GTE?

What's the legality of engine swaps when it comes to declaring the mileage on the odometer? Or does it really not matter if I'm not looking to resell the car?
>e.g. my car has 144,xxx on the clock but I want to swap in an engine + transmission that has only 70k

I have a 66 mustang with a cosworth YB on my list of future builds...

how light can you get a foxbody?
