The 009 is probably your best bet since the OE dist vac advance curve was matched to the FI intake air distributor. It probably wouldn't work right with your carbs, although it is still a very good distributor. > 4) Is it essential that I get the automatic chokes re-wired?

The stock oil bath air cleaner is amasingly effective. There is seldom justification for replacing it other than the fact that it doesn't fit the new system just installed. > 6) I feed the engine about a quart of oil every 350 miles, but I can't > tell where it's going.

Even if the cooler leaked only while driving, it would leak out onto the case and the case would continue to drip after the car was parked. > 7) I do not have a thermostat, and I think the heat control flaps have > been stuck somehow in the open position.

This continues to be a large source of misunderstanding. Your engine NEEDS the thermostat and all its associated hardware in order to warm up properly. Your engine only runs properly when the exhaust air is at 165F (or whatever the right # is). It is very hard to convince some people that the engine suffers any time it is forced to run either hotter or cooler than this. In your climate, the engine will probably warm up without the thermostat, the question is: How long will it take? It may well take 20-30 minutes, which means that on most trips it will never warm up. Remember, the best thing for your engine is for it to get to get through the warmup period as quickly as possible.
