Hot 318, carb choices.

I've been waiting for one of these threads to come up as well. For a hot street 318 like was mentioned, what do you guys think of the new Holley Ultra HP carbs? I have my eye on this one...The vacuum secondary electric choke unit is 670 CFM not the recommended 650...

And how would this carb perform on the OP's hot 318?
