I have a question regarding carburation for my 427 Side oiler, my car came with a Holley 770 CFM carb and I have been having issues with it. Rather than try to rebuild and go through frustrating trials and errors I decided to replace the carb with a new one of exactly the same specs; 770 CFM. I have been told after the fact that a Holley 650 CFM would be enough for I am not racing this engine. I have no idea what carb came from the factory with these engines, van anyone shed some light on the matter??
Your input is always appreciated
Regards

Lou,

Depending on your specs, a 600-650cfm double pumper, 4 corner idle circuit carburetor is recommended.....For when it comes to fuel consumption, bigger is not always better. Chassis (not engine) dyno does not lie


Perhaps post some specs on your engine and we can go from there.
