I'll be hooking the wide band up in the next few days.Wide band O2 sensor for mixture. Lots of guys "throttle stop" index classes.

That’s why I threw mine out.Vacuum advance seems to be misunderstood even more.
After watching the dyno tune at my engine builder make magic, I'll mess with timing a little. That dyno showed the engine was running rich but the timing and change in air cleaner worked perfectly with no further carb adjustment.Most carb issues are actually timing issues. Timing curve is very important, and usually overlooked. Vacuum advance seems to be misunderstood even more.
That sounds fun!I have a 4.88 chunk you can put in it for the weekends.

The only dyno's that really matter are either 1/8 or 1/4 mile long.
Add some weight to the secondary air valves in the carbs to slow the opening rate , should help your E.T.Maybe rig up a way to limit the secondary air valves and leave the throttle blades alone.
So while working on the carbs I seen that only the front secondary air valves are flipping open freely when I stab it. I've only seen the rear ones flip just a little once. They seem to move freely but I don't know if my engine has enough poop to pull them open where all 8 barrels are running. That could be for a number of reasons but when I go make some runs with it I will mount my go pro above the engine and see what I get from it.Add some weight to the secondary air valves in the carbs to slow the opening rate , should help your E.T.
Years ago Grumpy Bill Jenkins slowed the secondary opening rate of his Holley carb on his super/stock Camaro to lower his ET.
This also worked on my AFBs when I was racing my 62 Belair. ( this was before the use of stutter boxes) when drivers accually used their right foot to control starting line RPM.
