interesting car craft article this month on GM modules

You can probably open a can of worms with this one but let me say that this is from MY personal experience. I just purchased an HEI kit from Trailbeast on this forum a short time ago and can relate my experience with it.
My car starts better cold and a lot better hot than it did before the install. Gas mileage is about 2 mpg. better as long as I can keep my foot out of it(I like the sound of the 4 barrel kicking in). The spark from this unit is amazing. When I was doing my install, I thought I was ready to go and jumped in the car and hit the key and I could hear the crack of the spark(I had forgot to put the coil wire on). Couldn't see from the drivers seat but when I got out to put the coil wire on, I realized it was probably 3 inches from anything. That's a pretty good jump!
It also eliminates the ballast resistor. I know some people say "So what?" but if it isn't a problem then why do so many people also suggest carrying a spare in the glove box?
Lastly, the car just runs "different". I know someone on here wants to know what "different" is but since I don't run my car at the track all I can say is it idles smoother and has more seat of the pants feel than before.
Once again. Just my personal experience. Dennis
