So I have been thinking of replacing the 5.0 cfi, aod, and 7.5 rear end. I plan to replace those parts with a 347, c4, and 8.8 rear end. I was going to keep the original parts in case i ever needed to go back all original. I know the value of these cars is on the rise but is it worth it to hold on to all the original stuff? I want more performance but is swapping all that stuff going to far with a specialty car? I know the CFI/AOD combo is the "less sought after" version of the cars but its still numbers less than 1000 ever built. Would i be better off selling this car and trying to get another four eye GT or LX?
