8.The LS327 does not come with ignition coil mounts. The mounts are available through your local Chevy parts dealer. We found ours at the local junkyard. The MSD system plugs right into the coils and then only needs a 12-volt constant and switched power leads and a battery ground hookup. After that, it's just a matter of programming the controller or plugging in one of the providing timing curve modules (inset).
