definitly not msd. msd optis seem to have about a 50% fail rate, and iv heard nothing but bad reviews on msd wires and my personal set failed after only a few weeks. i used a stock delphi opti which seem to have great reviews. if it lasted that long stock, then why not use it again? and i use taylor plug wires which also get great reviews. the optis not a bad job at all, make sure to read lt1*c4's article on it, has step by step instructions with pictures

For my money the GM parts don't get enough love. My '92 has the unvented-type Opti, replaced with a new GM unit a few years back because the original had a little bath under the hood. But the original was over 10 years old, and the cap gasket had dried out, didn't take much water to finish it off. When a car gets old, especially if it spends lots of time sitting, the seals, etc. are prone to drying out. I used Delco plug wires also, they've been fine, and the lengths were perfect, very important on the LT1.

thank you,do you have any idea on a none electric water pump,mine has 90k on it.It makes sense to replace it at the same time as i replace the opti spark.
