360 does not seem to be making power and is slow in the 1/8. Need help and/or suggestions

My 2 cents the distributor, it has to be full advance at 6-800 to leave. My Duster with a a383 and stock street Hemi converter with 4.88 gears would do 1.65 60 run 7.35 eighth and 11.60 in the quarter. Work on the carb too, idle circuits are probably lean as he!! with that cam, close the air and open up the fuel bleeds. You’re getting those results with stock stuff.
