MSD's have all kinds of issues there anolog boxes and tend to have issues most racers use dual boxes just because they tend to fail. I've seen enough fail that i would never put one on my daily driver. Also in mst cases you dont need fancy iginition boxes for your engine. If your running very high compression or some type of forced induction they they are a benefit otherwise a stock electronic igintion is fine.
>>>>> that's true.... the analog CD boxes seem to be not as reliable as the digital CD boxes......the only reason Nascar still uses dual analog boxes is because they are mandated to, otherwise they would also be using digital switching CD boxes......besides the most seen & marketed 6A MSD boxes, Crane cams(now restructuring under S&S cycles) also makes a analog box dedicated for nascar use while their other CD boxes are digital...... the Crane Hi-6 I have, purchased in the early 90's is in it's second vehicle & has been very reliable...though I still do have my duraspark box & coil onboard as a back up.....while really benefical for high compression & supercharged/turbos it also seems to improve throttle response & combustion from idle with these multi-spark Capacitive Discharge boxes if you have a little overlap from a bigger cam................
