The factory installed Qjet on my truck is at paperweight status. It basically sweats gas.

Ordered the adapter to run a 2bbl on the stock high rise iron intake.

Pulled the original issue 40 years old distributor yesterday. New distributor, plugs and wires going in today.

Truck has a Th400 and 2.73 gears. Dual pcv valves, breather type oil filler cap, and still has the evap system. So will have to run a Ford style pcv compatible base gasket. 500cfm capable Holley.

Curious as to what drivabilty issues I should expect. Truck is an 85 C10 swb, with a 4.3L V6…

A Q-jet has smaller primaries than a 2 V Holley 500. Provided your foot doesn't open the secondaries Q-jets are an economical design.
