2 barrel , 4 barrel, whose got the answer?

The TQ & QJ are great carbs, but no longer available new or with a jetting kit.

I would use a dual plane 4 bbl intake such as the Performer [ not the RPM ] with the Edel 600 #1400. This has an elec choke & is jetted for max economy. It also has all the reqd ports: ported & man vacuum, PCV, brake booster.

To best utilise the features of HEI, use an E core coil such as MSD #8207, no bal res.

Use 0.060" plug gaps.
