I just got done doing a full tune up on my 99 jimmy with 123k miles. I replaced the plugs and wires with delco. A buddy of mine who ownes a local shop suggested a skip white dizzy. I was very skeptical at first but he really knows his stuff and for about 50 bucks shipped I figured I would give it a try since that's how much a new cap and rotor would cost. It came very well packed, the shaft is aluminum and the machine work on it is very nice. My only complaint is that it has an accel cap and rotor. But after 3000 miles it hasn't missed a beat. Once it does I will swap them out with delco. After I removed the stock distributor I was surprised to see how much play there was between the rotor and the splines, alomst a quarter inch. So if anyone is looking at a cheaper altenative to delco I would recommend a skip white unit. The lifetime warranty is nice too lol.

Not sure if this is the right place to post this review, and its not spam, just my honest opinion, take it for what its worth. I will also do a review of my blackbear performance tuned pcm when I get it and have had a chance to log some miles to give an honest review.
