Being in California, I'll assume you have emissions testing at least, and probably inspection. That being the case, listen carefully.

You need a factory V8 donor car that's your year model or newer. Take everything out of it that's different with regard to the engine, and put it in your car. That includes that little iddy biddy list you started, and a whole bunch more. Add the tranny and wiring harness, by the way (the harness can be removed from the engine/chassis in one piece and re-installed - including the sensors that are attached to it).

Change the front springs. If your car is earlier than '89 or '90 or so, the radiator. And the tach.

Hoses, throttle cables, belts, AC ...
