I put one in my current 440 when I built it back in 2005. I don't remember any problems but I did switch to a billet MSD at some point. The DC/Mallory was supposed to be the latest and greatest back then but I remember some bad press on them. work I did buy the recurve kit and got the advance where I wanted it before swapping in the shiny new MSD. wrench
