Hey guys, I was screwing around on FB marketplace and came across this boat with a "Corvette engine". Normally I roll my eyes when I see that, but this does in fact appear to have an LT1 in it, minus the optispark. What ignition is this thing running, and how hard would it be to get into a car? Thanks!

Here are some pics of my Coil Pack unit pulled from the motor. I have pretty much determined this is a ICM issue because of some corrosion I found on the male prong for the specific cylinder I have been having problems with. I am going to try and clean up the ICM and reinstall everything (using Di-Electric grease to assist in corrosion prevention) to see how she runs. If need be, I have all the info I need to start swapping out parts to get the mis-fire problem under control.
Pictures Legend: 1st - Coil Pack/ICM unit mounted on the motor. (just follow the spark plug wires to find yours) 2nd - Coil Pack/ICM unit removed from the motor. 3rd - Coil Packs (4) removed from ICM. 4th - ICM unit. 5th - ICM prongs up close with seal removed (showing minor corrosion)
If you're looking for a less spendy option, I've been working on a arduino based coil per cylinder setup for the past couple years that picks off the opti signaling. It's still in the experimental / test stage but I feel like I'm really close to fixing the last outstanding issue. I've been looking for ppl willing to test for months with no takers.
