Sounds like a Holley (or MSD) dual sync distributor would clean things up a bit for you but not really required since you have the system working.
Yea, grinding all but the #1 tab off and configuring the ECM for hall effect was the Holley Tech's idea back in 2014, which I did suggest to Holley that they add a dual sync RB dizzy into their product line. Look like they obliged, and I may swap it out during the cam change as it would be a cleaner signal than "analog" pulse.
