is 600cfm big enough for 350ci

i have a slightly modified 350 with a holley 600. the car runs good but it feels like it has more to give. i have an edelbrock torqer 2 and i'm about to change it for a performer. can a 600 cfm give a 350 small block chevy enough fuel?

It should be plenty for a mild build, you get into good heads/cam and it may become a limiting factor.

buy the performer rpm for one. If this is the single feed line holley 600, i would recommend locating a holley 650 double pumper and that will be a solid HP increase and fuel economy would be similar to a vacuum secondary carb if you keep your foot out of the secondaries.
