Ok, now to answer some questions that I've seen. It isnt the MSD box causing the popping, because with the bypass adapter in on back to back dyno pulls, it still popped. As far as I know, the coil pack and module have a good ground, and the spark plug wires are in great condition. I've also heard alot of people say that you have to widen the gap with the DIS-4, then again, I've heard alot of guys say to tighten the gap to .025 or so, its just alot of mixed opinions, and frankly I dont know what to think. I dont wanna tell my dad to try the wrong thing and have it pop and blow another gasket. All I know is that with Autolite 103 plugs gapped at .035 with the MSD box bypassed, new coil pack and module, it still popped. Dont know what it is, but what like to find out
