The Optispark is your distributor. It routes the power from the ignition coil to your spark plugs.
Odds are you have an optispark unitl. If so it is under the water pump on the front of the engine. Look up optispark replacement on LT1 or C4 Corvette.
the dealership will quote about $600.00 for the optispark alone. they quote 10hrs at 60.00 shop/hr
