Only illegal if the car that is being destroyed is stolen. If you keep the titles for both cars, and document the swap, you're good to go.

Why everyone gets their panties in an bunch over this is beyond me. It's nothing different than a motor swap...

In Cali, they look at all numbers when inspecting a car, and if your eng # doesn't match, you have to prove where it came from, as they're on the lookout for theft.

This is no different.
