MSD id never use again.... get a used EFI ecu and never look back....put coil on plug and your timing can swing as far as you want and be ROCK SOLID....
MSD snafus will eventually cost you pistons or more, then what will the cost be ???
This is disappointing to hear, after getting a grid and all the fancy doo-dads, we were likely going to go to a big fogger kit on the 655ci. It's been as reliable as a stone so far, the only thing that's "broke" is a crank trigger sensor going bad and causing a misfire but I suppose if that went west while on the gas things would go bad in a tick...  What issues have you had with MSD stuff ? TIA
