I just got my C-4 rebuilt locally with high performance clutches and bands for $500. That included having to replace the clutch drum. The main problem was finding the parts. We finally converted to a 26 spline input shaft because no clutch drums were available for my 24 spline input shaft. That meant I had to convert my TCI Breakaway convertor to 26 spline. That cost an extra $100. I'm betting you can do a high performace rebuild locally for $500 if you look around a little.
