All of the Edelbrocks are typically lean once you get to the point of tuning the main fuel circuit. Regardless of cam, compression, gearing, convertor, or any differences in engine builds, I've never had to change squirtors on a Edelbrock or Carter. If you have one, get the timing curve set properly (and unless it's a full on race car you need a curve rather than a locked out set timing amount and should run a vacuum advance off the ported vacuum port) and get it idling right witht he right step up springs, jet/rod it right, and they will outperform almost any Holley or holley based product on a street car.
