416 dyno tuning help

Thanks guys, when we go back we are going to set timing around 32-34 and change jetting on carb to 70's on primary side to get the AF ratio to at least 12.5
Also will be bringing TTI step headers, the motor was running some no name 1 5-8 header
Also need to find out what the final compression ratio is,

Good luck. Results should be much better. Would wait to lean the carb until after a pull or two. Larger pipes and the timing changes may end up requiring more jet?
