904 advice needed

Thanks all: I have the DVD on the way (thanks crackedback) and have decided to rebuild it myself. Unsure about the converter but probubly just by a stock reman or something. I have a friend who has done a 727 and getting ready to do another for his 71 Challanger so I will help him with it to learn then we will do my 904. I am putting the money I will save into a 5HP air compressor so I can get on with the bodywork on my ride. Great advice from all!:)
