Hello Carsten,
I was hoping somebody would jump in and answer your question but nobody has so I'll add my .02 cents.
The Holley 4160 series (3310 model number is one) is similar to an Edelbrock in that the secondaries are vacuum actuated. The difference is that on a Holley only the primaries open when you move the throttle lever. On an Edelbrock (which is a Carter AFB) the secondaries are mechanically opened with the throttle, but the "Air Doors" above the secondaries open via vacuum. This is similar to the operation of the best carburetor ever produced the Rochester Quadrajet.
Due to this fact, Edelbrock won't have a recommendation as holley would between vacuum vs. mechanical. I believe the more performance oriented Edelbrocks are based on the Carter AVS vs the AFB. Sure some Mopar fans here can correct me if I'm wrong on that fact.
I believe the AFB also has all of the gas contained in the carb under the gasket line allowing a person remove the top of the carb to make changes without spilling fuel. On a Holley you have to empty the bowls, either in a cub or on your intake manifold. :-)
With your low stall convertor I would stay with a vacuum secondary carb. A vacuum secondary carb is a band-aid for low stall convertor vehicles.
I don't have much Edelbrock experience but many fans of the carb choose them over Holley due to easier tuning, better street manners and fuel economy.
I do have experience with a Holley 3310 and it is a great carb also. This is probably why it was installed on so many vehicles from the factory in the late 60's.
Either a 4160 Holley or Edelbrock would work nicely for you. I personnaly would recommend an Rochester Quadrajet from Sean Murphy. I have one on my 70 pickup and it runs like it's fuel injected. Sean did Jet's line of carbs and really knows his way around a Rochester. The Rochester will provide you with the best driveability and best fuel economy.
