Default New season, new settings

As the roads got snow- and icefree this week, my 347 will be out of the garage and hopefully also on the dyno very soon.

What changes have been made?
- Idle jets up from 45 to 65
- Main venturi up from 38 to 40,5 (were 40, but after polishing/ reworking, they grew...)
(Larger main jets were cancelled as mid- to higher throttle showed a rich blend.)

Hope this will make the midthrottle- driving, AKA the transaction ,better, as I hope the larger venturis will start sucking fuel from the main (accelerator?) jets a little later.

Hopefully, the larger venturis will help deliver the full potential of the engine as well.
And while we're at it: can someone give a estimate of CFM of these carbs?

Happy easter holiday
