some msd/o2 sensor experience needed

You should be okay at the 100 miles, just keep an eye on the gauge when it starts reading differently after a while and you know it's not reading what it used to, then pull them and clean. Your gonna run race gas all the time or just most of the time with occasional pump gas?

I had to drive my neon for a while till most of the lead gas was out of the system before I put the catalitic converter back on.
