SLP can handle the dyno testing. There is at least one member in NJFBOA that can help you with reprogramming. In fact, if all you are doing is rebuilding and not modifying, there are probably plenty of folks here who can help you. There's plenty of 305 and 350 experience. And look at how many guys keep saying they are bored and want something to do.
Buy the materials yourself, then set up a weekend project in your garage. Pizza, beer, tunes, and a heated garage will be welcomed by many.
