Hey guys I will be installing my exhaust soon.(Check my Sig) I know I'm gonna have to change the jetting on my carb for the increased airflow. What size jets should I run? I am in Utah at 4500 ft elevation. I don't know the current jetting on the carb. Its a 600 cfm Holley 4010 on a 351 Windsor Mach 1. What other things will have to be tuned for the car after I install the exhaust. Im new to this so bare with me. Thanks in advance.
