Hate looking at carb stuff.. kinda wanna run a AVS2, never had any issues with cart/edelbrock type carbs.. but also ran holleys without issue... gonna read all day adn go back and forth in my head for a bit :)

One thing i don't get is they call this a square bore carb... i thought this was a spread bore?

That's set up with the two most common bolt patterns.
But the difference in throttle bores you see there are not spreadbore.

This is a Holley 4165 with a 'Spreadbore' throttle bore positioning and bolt pattern.
