Default What is the difficulty of installing an Optispark

I see where the difficulty of installing an Optispark on an LT1 has been questioned. Here are a few photos showing the steps for installation:

Here is an image of a 92 LT1. The antifreeze, air cleaner system, water hoses and drive belt are already removed.

Here is the water pump. If you peer down this hole, you can see the Optispark and connector beneath the water pump.

Six bolts and the water pump comes off. Dude.. It is filthy back here.. Unfortunately, due to the Optisparks location, washing the engine is a bad idea.
Now you can see the factory Optispark. It sits behind the harmonic dampener.
