Hi Jon.

If I were to open this 1406 up and try to tune it, any idea what’s good starting point might be for jets and rods?

The stock original AFB will run much better on the 326.

A properly tuned Q-Jet would run a wee bit better in city driving with a stick, not so much with an automatic unless driving is sufficiently spirited to downshift. Should be no difference in how the engine runs at highway speeds conparing the Q-Jet and the original AFB.

A properly tuned Q-Jet would probably do a wee bit better on city driving fuel economy. Again, no difference on the highway.

A properly tuned Q-Jet would have less propensity to "hot soak" than the AFB.
