Keeping the charger original ,my question is my 318 is bored 30 over and I believe a tow cam. Was going to slap a 4 barrel intake on but now was thinking just putting a 2 barrel 500 cfm holley instead. Will have duel exhaust on it. Whats your thoughts on this? I believe I will have to get a different air cleaner. This is a cruiser not a race car. Thanks.
