Spark Scatter

so ive noticed my 73 swinger that trying to time it can be kinda hard... the mark is all over the place.

i checked the timing chain and am only getting two or so degree's movement

gear on the distributor is new

running the stock electronic ignition but with a ballast bypass and 60K Petronix E coil. Blue Streak Cap, 8.5mm wires and NGK plugs. Its also curved to 16 initial, 30 total by 2500, 52 with vacuum adv (Can VC208(11R)).

is common due to the stock box or may it be somethin else? im wondering if this is what is causing my idle miss and ok mileage.

thanks!

P.S. if you want a video i can try and get one tonight so its really obvious.
