How's it been running the past few years? Lol. I wish I had seen this thread when it was still "active" I would have strongly suggested rigging up some type of warm-air intake for cold-weather driving. Even with the non-Air Gap intake manifold it will take quite a while for it to heat up as there is no exhaust crossover, the only heat it gets is from oil spraying on the underside (which also takes a while to get warm itself) and conduction from the heads which isn't great due to most of the contact area being separated by the intake manifold gaskets. You can do your best adjusting the choke, timing and whatnot but fact of the matter is, until the intake manifold gets warm there isn't enough fuel vapor and you are sending tons of unburned liquid fuel through your engine which is washing down your cylinders and diluting your oil.
I don't know many people with built carb'd engines without exhaust crossover trying to drive them in sub-freezing temps. I do it but most people here in the states put their muscle cars away for the winter and only drive them in warmer weather.
