i am going to install a GM "zz4" in my 79 camaro. I would like some advise on what size carb to use. I currently have an edelbrock 600cfm w/electric choke. My goal is to have a well rounded and fast street car. I was thinking I need to go with a 750cfm. I am partial to the edelbrock carbs. The motor specs are: 355hp@5250rpm comp. ratio 10:1 valve lift: Int/Exh. .475"/.510" Duration: Int./Exh. .208deg./.221deg.@.050"tappet lift 1.94"int.&1.50"exh.valves and 58cc combustion chambers. I have currently selected Sanderson blochugger headers 1.5" tube size $ 2.5"collector size.
