Using CID x 2 I would need a 710cfm carb....Big difference. A debate on correct sizing is not what I'm looking for here. Here's what I'm after... I have a 390cfm double pumper that came off a circle track(short track) car with a 355cid engine that lived in the 5500 - 8500 rpm range. I'm wondering if it will be worth the trouble to put it on my motor. It has a 355cid built for 2000 - 6000 rpm range, but I have an automatic. The carb is one of THESE.
My own personal opinion is that it will be more trouble than it is worth.
