Don't read if you're close minded

You mean the test where they dyno tune the carbs on a chassis dyno then take them to the track to see how they actually perform?

Was it the test where the engine ran fastest with 5 inches of vacuum at the top end with all those pumping losses?

Why did it run fastest and idle best with the smallest carb and 5 inches of vacuum?

That's one car, doesn't mean the results for that car is universal to every one else's car. It's interesting but you would need a few thousand more examples, to offset the last 65 years or so of racing and hot rodding.
