Gotta watch some of these MSD knock off Chinese distributors. I bought one of the TSP MSD lookalikes and couldn't figure out why my timing was all over the place. Turns out that end of the distributor that fits into the cam gear slot had such a sloppy fit that it allowed about 10 degrees of timing variation. It was the same price as the one you're looking at and I wouldn't be surprised if they were made by the same manufacturer and just put in a different box. I wound up buying a MSD and haven't had any problems since. I have found out that sometimes you get what you pay for.
