Hmmm what I will be doing next Summer?

I don't think yours is the 85551 I said before I edited. The 85551 has no vacuum on it so yours will be similar but a different part number. Almost all MSD distributors have melonized gears and the top models all have a coated gear.

It's the 85551 msd distributor, it will be ran on a cast comp cam hydraulic roller cam. Been looking and have had bad luck finding out if the supplied gear will work.
