Tuning For Detonation

Looks like you have tried just about everything under the sun to stop the ping.

Like the looks of the orientation of your carb facing forward and easy to do the throttle linkage.

But . . . Was wondering about you turning the carb 90° to face to passenger fender for more even fuel distribution to all 6 cylinders? Have seen other custom /6 4bbl setups with the carbs sitting on them sideways.

The way it is positioned now 3 cylinders are getting a lesser charge than the other three. Being the 4 bbl is spiit in half, sending the primary butterflys to the front 3 cylinders, and sending the secondary charge to the back 3 cylinders.

Know you mentioned it does not make a difference, but think worth a try being everything is right on the edge of getting it right. Nice even fuel mixture to all cylinders. 10:1 compression without ping should be easily achieved.

It either gets better or it gets worse, process of elimination.

I would even try another carb you have laying around, either gets better or worse. Then go from there.
