Seems you're taking this personally, I don't know why. I've not said you're wrong. I spent 12 years working for OEM's. Not in engine design however. Edelbrock has been making carbs a few years, so I trust their numbers and their tables. I've been tuning for a few weeks. But in that time I can say, no way in heck my engine will idle, at least not well, trying to achieve 14.7. It would have so mean lean spikes (misfires), it would be horrible and would barely read 14.7 because it would continually jump above that due to misfires.
