this morning I went to see my machinist at his shop, hadn't been over there in a while, he specializes in flatheads, and there sat his new setup on a flathead, he's making the blowers with 2 97's on top, he makes all the pulles etc for the drive and also told me he has taken over all the Navaro flatheat stuff..I will be returning in a few days and will take some pictures if anyone is interested
