carb. crazzzzyness!!!!!!!!!

For a general rule.
Auto cars=Vacuum Secondary
4spd cars=Double Pumper

I like Edelbrocks. I can take them apart,adjust,and tune them blind folded. I like their dependability,and consistency. Can you squeeze out a couple more ponies with a Holley? Pretty much. But for day to day street cruising,with
their dependability, I think they are a great carb. I run a 500,600,& 750 on my cars,all with great sucess.I also like the fact that all the factory linkages hook up as designed. Basically it's a Carter.
I would have no problem putting a 750 Ede on your 440.
What ever carb you chose,go with a vacuum secondary carb,with your auto.
PS:Ignition first !
