Carb Question

[Quackaddict]

Redoing my motor and the Q-jet that is on there is in sad shape. Been looking around and have found 2 that I am really interested in. But I am a carb virgin here so I don't really understand what to look for and what to stay away from.

One has electric choke I am not sure on the other......but I don't even know if I have electric choke??????

My Motor: 1978 454, 781 Heads, headers, Air gap intake, HEI.

Carb 1 - 850 CFM Holley Double pumper, supposedly has been already tuned on a running motor for max performance etc, etc

Carb 2 - 750cfm Edelbrock 1411 series pretty much brand new out of the box.

There is quite a difference in price which isn't an issue and I am not looking for a edelbrock vs Holley arguement.

The issue I am trying to figure out is would one be better for the motor or would my motor since kind of stock not benefit from an 850cfm or is 750cfm to small those kind of issues.
