650 or 750 Edelbrock on 340

I really do not think someone who builds engines and dynos them has trouble tunnng a carb its pretty easy
and they have all the readings to do it
Wasn't talking about them, talking about guy who buys a used who how was tuned before or even new say 750 throws it on some mild engine do little to no tune then decide it junk.

Just speculating where this fear of over carburation came from, not saying you can't but it seem way more for giving then some make it out.
