I want to replace my old quadrajet, with a nice carb.its seting on a 350 with a manual choke,any suggestions?

 

Side draft Webers?

 

Better yet...how about dual quads on a tunnel ram?
Or, a 650 Holley sitting on top of an Edelbrock Performer Air Gap manifold would be a good second choice.

 

for your application ill assume a stock or mild motor id chose a 550-650 cfm edelbrock carb. 550 for stock and 650 for some aftermarket goodies or plans for them in the future. they are a good, easy to adjust, find parts for carb kurt
