Ok Carb experts. I have a sb400 with a mild Cam. Currently I have a factory 600 CFM Edelbrock Carb. After reviewing the Edelbrock calibration sheet I'm thinking about increasing my metering rods to the 1458s. According to the calibration chart this should put me at a richer (%8) fuel mixture under heavy loading and still maintain an even base mixture while cruising.

I'm not worried about fuel efficiency during WOT however I would like to have decent fuel economy while cruising. The 1458 metering appear to be the option I'm looking for with out having to swap out jets. I also plan on adding heavy springs that are recommended for the vacuum I'm currently running.

Any thoughts or suggestions? Thanks guys I'm new to tuning carbs.
