I have a 355 chevy SB with a 270 INT./280 EXH. cam, Edelbrock Performer RPM intake, and headers. Some minor work has been done to the heads, but nothing to extensive. I have a Holley 600CFM marine carb. Could somebody tell me if this marine carb would work and if it would even flow enough CFM's. Or should I get a Edelbrock 750CFM, or would that flow to much air. Any help would be appriciated. Thanks, Bobby.
