OP, here's something that should be considered when choosing your induction system. A carburetor will need a few things to make it a pleasant start and drive. You'll want a choke, manual or automatic, for the cold starts. This is fuel enrichment for cold, dense air. Electric chokes are the simplest, but work at the same rate of opening in all temperatures and can be fickle in extreme colds. You'll want a heat crossover for optimum driveability on a cold engine, but a heat crossover works best with a heat riser valve in one of the exhaust outlets, this requires exhaust manifolds. This keeps the fuel from condensing on the floor of the intake manifold and helps keep the fuel in suspension for proper atomization.

Port fuel injection negates all of this. No heat crossover, no chokes, no heat risers required for cold engine driveability.

You're in Ontario Canada? Brrrrr. just one more thing to consider.
