A mixed review depending on desired engine RPM. The review is based on 3 different dyno engines, one SBC, one SBF, one Cleveland Ford (mine). In each case trigger was consistently stable until 5750-5800 RPM. Above that point, trigger varied + or - 6-8 degrees in timing. It is a great upgrade for most street engines. Not so good for use above 5800 RPM. If you want to rev above 5800 go with a Dura-Spark II or MSD distributor.
