Can anyone tell me if there are any versions of a Gen2 that came out with distributorless ignition?
I have a Lt1 5.7L MPI corvette engine in my ski boat which is fitted with a ignition module and 4 individual coils, the motor is marinised by Indmar, i am trying to get hold of a new Ignition Control Module .
i cant seem to find any variants that run this type of ignition, they all seem to have optispark.

Not in a production Corvette.
 As you have found out all LT1's had the the Optispark
Yours is probably the aftermarket Delteq 4 coil conversion ; uses a Delphi ignition module  
Does your module look like this ?

stevemx:
No thats not the same, i have discovered that the module is interchangable with the unit used on cadillac Northstar engines, which are easy to get your hands on.
But thanks for your help guys
