i have 73 duster with 6oo cfm edlebrock carb what is proper way to adjust with vacuum gauge, also i think my timing is off some, i have slighty built up 360 with the carb above, 3"hooker headers into dual 2 1/2" dynomax superturbo mufflers,pertronix ignitor ignition and flame thrower 2 coil,mild cam, my approximate hp is 370, automatic car. can someone tell me what my timing should be set at?any advice would be thankful
 
most mildly built s/bs like 32* to 34* total Where it pulls the most vacumn is where its running the best.
 
how many degrees does damper pulley show, i am new at this, do i just put timing light on damper pulley and rotate dist to 32* or 34* i have digital light? thanks and do i take vacuum of dist
 
Yes remove the vacumn line and plug it. I just recurved my MP distributor so I could run 20* on the dampner and a total of 34*. My motor runs better with that much initial advance.
