A/C (converted r134a)
3.07 Open rear end
Gauge cluster was upgraded to have a Tach, which still coming off the coil. So no problems with the tach!

I am using full manifold off the intake tree behind the carb to go into the distributor - I had to split it off from the client control vacuum reservoir. This old 72 Qjet only has the one full vacuum port in the front for PCV Valve & EEC charcoal canister. I wished that vacuum port on the distributor was pointed 90 degrees and not straight down - its a right PITA to get the hose connected!
Did you get a new coil too, or keep the Flamethrower from your old Pertronix?

You're really making me think about this too... Once I get off my a** and use Cliff's rebuild kit on my QJet, that dizzy might just have to be next... a little pricey but it sure sounds like a big improvement.
