i was talkin to a coupld MSD reps at the Presidents cup at MIR and aparently they are developeing coils specific to the LSx and soon after those come out there will be an ignition system sepcific to the LSx motors as well. itll be money though. the coils i believe are to be out some time late this year maybe next. its not too far off and no more wiring up 2 dis 4 ignitions, this would make things a lot easier.
