Have a hemi predator, have ported it out, assuming ive improved the airflow. I want to bore the stock carb. I havent done it before so im looking for tips and advice. I have multipul carbs so im not to worried if i dont get it the first time around. I know i will have to rejet the carb. Im running arc intake, free flow exhaust (home made), bsp3 cam. Any help is appreciated.
