*noob*

1.) Should I even worry about getting a 'stolen engine' when I go engine swapping on CL?
2.) Do I need an paperwork on an engine, like where it came from, sales receipt, etc?
3.) How do I do all this paperwork?
4.) In Florida, do I need to register a swapped engine with the state/PD? Or anything like that?
5.) Are engine swaps even legal in this state?
6.) Is there some sort of database where I can go to, to see if the engine is out of a stolen car or anything of the sort?
7.) Do we have any laws concerning modifications to cars of a certain age? Like, if a car is older than xx years, are the laws different? How?

I'm obviously in Florida, have a 91' CRX, and I'm looking into swapping my D15Bx for a D16A6/D16Z6, if that matters.

Thanks in advance..
