I would put the Edy performer on with a Q-jet if you can tune & dial in the carb. yourself. The Q-jet primaries give good drivability & gas mileage. Then when you get on it the secondaries give good power & neat sound. GM used Q-jet carbs on many small displacement engines with great success.
The Pertronix has a poor reputation for reliability although I have used several ones for years without any problems. The exhaust manifolds are OK but I would ad dual exhaust.
