Edelbrock out of the box NEVER again.
Had three of em first only one side was working Rite out of the box. 2nd one leaked like the titanic.
The third one was ok never got any MPG out of it but it always ran.
I like Qjets and Hollys best MPG will be a Q jet Put a kit in em make sure thre clean and set the float level and you will be pretty dang good.
Hollys are good but more for perfomance and They can be tuned anyway you want them So easy a Caveman can do it.
Alot of peoples problem are self enduced Like putting a pencil in the choke butterfly and then blaming the carb for non running right.
Learn how to set the choke and then re learn to set it.
I just wish i could get a polished Q jet.
