Have had the same problem with using the stock distributor with bank to bank and the MSD dual sync with sequential. Talked with David no longer with FAST and Jeff my trusted chassis dyno and tuner it is the distributor being driven by the cam seeing harmonics from valve springs etc. At least with a Ford it is driven on the front as opposed to SBC which is in the back and sees it all.

Crank Trigger cleans up most of the noise and provides more accurate timing would be the fix.

But racing stock it's a no go so do your best to shield the noise and deal with it. We can chase our tails with electronics to be more accurate therefore efficient therefore fast but still we need airflow to add fuel to tune.

Stock is not Stock
Stock is way cool
