I'm not sure the final verdict is out, but I would plan on having to pass emissions myself (I am until someone tells me otherwise). Just build a EFI 302, leave the AIR pump intact and get a pair of cats to put on for the inspection. If you need power, build up the stock 302, supercharge it, etc. You could still pass.
As for wipers, yes you need them, and reverse lights too. Not sure if I left anything out.
