Well the old girl is final dead. The SB400 is fouling plugs once every couple of weeks, shes blowing blue smoke, and she just doesn't getup and go like she use to. I had an engine builder all lined up, but I found out the guy is a flake. So know the search is on for a good builder who is willing to warranty his work. Living in California the only way to get a high hp,high torque motor and pass smog is to have one custom built. A good GM crate motor won't pass smog. When all else fails MASH the skinny pedal!
