I will disagree,if you are not experienced with rebuilding carbs stay away from the Q-Jet, if you can find one that is in good working order then use it.The Holley is much more "user friendly" and parts availablity is much better and tuning it is much easier.If the Edelbrock intake is a 2101 Performer the only "adapter" you should use is the Edelbrock EDL-2732 base gasket,the aftermarket adapters that are made of pot metal and have the offset holes disrupt flow and should not be used.I really cannot understand why folks on the boards would tell you to use the Q-JetI buy and sell used carbs to have "play money" for my project, the Holleys,AFB's and Edelbrocks usually sell within days Q-jets you almost can't give away! check ebay for Q-Jets almost zero bidding on them or dirt cheap,what does that tell you?
