Default Carb CFM Question ??

I am going to put an Edelbrock 2131 intake on my 1974 Jeep CJ5 with a 304 V8 and I am trying to find out what size carb to put on.

First off the Jeep is a fully restored show Jeep.... no off roading! It has 9:1 compression, a mild cam, Jet Hot coated stock exhaust manifolds (which flow pretty well) and a stainless free flowing exhaust.

The RPM range is quite low and I would say the max would be 3500 RPM.

When I run the numbers on a 'CFM calculator' it would seem the Holley 0-8007 with 390 CFM would be fine.... That just sems a bit meager to me... I guess I am guilty of more is better!!!

Thoughts??? Thanks!!
