Need some buying advice. 71 Scamp

The Scamp belongs to a good friend of mine, it should be good to go as is since he's pretty anal about his cars but I think he has an itch for another fast late model, he had a pretty quick LS1 camaro he sold to buy and build the scamp.

It runs really good as is but needs a cam or gear swap to make the most out of the combo, I would do the cam swap myself.
