Well, there's a terrific set of books that can help you greatly in rebuilding the engine by yourself. The "How to rebuild your small block MoPar" and "How to hot rod your small
Block MoPar" books show a lot. I rebuilt my first engine from the rebuild book. It worked out great. I also had the MoPar "Engines book" which you can still get.
Do you have a planned gear ratio in mind? Tire size? Ideal cruise RPM range?
