A: If you are doing high performance, then using a degree wheel with a hi-po cam is a definite boost in the power dept. From: Marty Bricker <mbrickerusn@xxxxxxxxx> Subject: Degree Wheel use To: AMC List <mail@xxxxxxxxxxxx> OK, once again showing my ignorance, do I need to use a degree wheel when rebuilding my 258 engine? Neither the TSM or Haynes mention using one but I see them being used on 2 Guys Garage, Hot Rod tv, etc so I'm confused. If so, what kind should I purchase (JEGS has several different ones listed...the only place I could find one). Hopefully it will also come with directions for use...! Thanks. Marty
