The Ignitor conversion works great! We turn 7200+ with ours in the MoPar powered FED. Had it in a 383 (+.060"-395") and now the 471" stroker, ran 5.50 with the 395 and now runs 4.90s with the 471. No problems, we use a HyFire Mallory box and Accel CDI coil. You can use it with no box to fire a regular coil! Awesome setup, glad I could help... RB
