Firecore Distributor

I am looking at the MRE90430. To run with my rev-n-nator. I just was curious what all comes with it. I want to be able to tinker a little more with my timing and what not. I've heard of others having problems. But I will be dropping mine in and running it asap, so I don't think I'll have to worry about warranty expiration or anything.

I wouldn't mind sending out to recurve my distributor. But I am big on doing a lot of this myself. I want to know every facet of my car and really get it dialed in for best performance. Plus it's the best way to learn and ignition/distributors are always a place that seem mysterious to some. And I wanna learn as much about it as I can.
