Never underestimate the importance of a properly running ignition system
I decided to upgrade the ignition on my daily driver yesterday. It's had a difficult time starting up since the day I bought it last June so I figured the ignition would be the best place to start upgrading in order to (hopefully) fix the problem..
After looking at the distributer cap and pulling out one of the plug's, I realised they were either the origional factory 17 year old components
or not too far off. The plug's were all fouled up and the gap's were too big on three of them. The wires were really dry and cracked due to the heat throughout the years and the cap and rotor had both seen better days.
I went ahead and purchased the following:
*MSD cap
*MSD rotor
*Taylor 8mm pro wires
*NGK plugs.
I'll be ugrading the coil next paycheck with a new factory delco unit.
The plug's were a pain, but no worse than on my LT1. Four were accessed from above, the other four from below.
All I can say is WOW!! What a difference it made. The car start's right up and idle's as smooth as a Lexus
Throttle response is much better and the car pulls a lot harder throughout the rpm's. The biggest difference is out on the highway. She run's a lot smoother and there's definetely a notable power increase.
Even though I haven't driven it much since the yesterday, I wouldn't surprised if I got an increase in gas milage as well - infact, I'm betting on it.
Never underestimate the importance of a properly running ignition system. If you're ignition system is not up to par, it doesn't matter what other mod's you do, you'll never see their full potential.
It's a relitevely simple, cheap and very effective upgrade and if you're still running the old factory stuff, take my advice and change it right away.

When my V6 rotor failed - it gave no warning before hand. Car just died and didn't start up. You all should at least replace those ignition components if you haven't in a long time or never. Especially with winter coming and for what ever car you drive for it. Thats if you have to deal with snow.
Very good idea, LT1Fun.
