Also - tried WD40 in the rough area I think the opti/coil/ign but to be honest I am not sure exactly where they are on the LT1. I believe it to be where I can see the spark plug wires join together in what I would have called a distributor (not sure if opti is the Vette equivalent) - this area is located towards the bottom left of the engine block if you were looking at it head on (this is the area I used the hair dryer on to get it to start last time it was soaking out)

If you folks have any images which might help me better isolate the opti/coil/ign on the block then I sure would appreciate it
