1966 sport fury upgrades

Hi I recently bought a 1966 sport fury with the 383 commando. My question is what are some reasonably priced upgrades for it. Exhaust wise I'm keeping either the stock manifolds or trying to find some hp manifolds that will work with it then running 2.5 tubes into glass packs. I'm looking more into reasonable priced engine upgrades engine wise like the cam or carb or anything to get more oomf out of her. Any help is greatly appreciated. Also the scoops are fake but was considering making...
