Tools I Have Found Useful

Fantastic balancer puller/installer tool Precision Performance Products harmonic balancer puller/installer kit.  I bought one of these after breaking one of the cheap-o pullers that I had gotten from the local Kragen store while trying to remove the balancer.  The balancer came off so easily that I was shocked.
PPP Crank Nut Precision Performance Products Crank Nut.  This little baby is a permanent addition to your engine that will allow you to put a socket on it and turn your engine either backward or forward without having to worry about breaking the bolt loose in the process.  It can be a real boon.
