Eddie, IMHO I used to have an MSD AL before I accidentally burned it up!. Anyway I liked it and felt like it improved my cars performance with "seat of the pant" tests. Idles seemed smoother and nicer acceleration. It all makes sense when you read what they do.
But That particular unit may be a little overkill as of now, you might want to check out the MSD Street Fire version. This one will save you some dough and does what YOU probably want without the race style hi-rev, Hi HP features.
But I also want to add if you keep your engine tuned properly with a pertronix, for the most part you'll be good to go. The 180.00 bucks for an msd could go to something else. Just some thoughts about it.
But I'll probably get one anyway!
