I have a 96 LT4 with 25,000 miles and it looks like I have to replace the water pump. I'm also going to replace the serpentine belt, upper and lower radiator hoses, thermostat, and plug wires. Although I've never had any problem with my opti-spark, I'm considering replacing it because it's so trouble prone. Any comments on the opti-spark or any other item that should be replaced while I have it apart is appreciated.
