To Much Cam?

It sounds like you did get the build pretty much right. I had concerns about that but i feel better seeing more detail. I do think the cam will be a little soft in any event with your current gearing, but I also think you may be a little confused on the stall speed and rating of a convertor. Stall speed is a function of power and resistance to that power. So if the engine is soft at low rpm as yours is, the stall speed will be lower. In addition, each convertor has two: Brake stall, which is what you are testing by holding the car still and flooring it... And flash stall, which is what the engine speed raises to when you are in high gear at about 30mph and floor it (try to not let it downshift). If you do that is it higher than 2300? I think a gearing change and maybe some tuning will bring it where you want it.
