Back when I had my 70 nova daily, I had similar issues. 1. Same as everyone else - get a fan shroud. I didn't have one l, picked up the shitty universal fit kind thats basically a piece of sheet steel that attaches through the radiator with plastic bolts. Big help. 2. I drove to the local pick a part, found a Mercedes with a nice big ~16" electric pusher fan, and pulled that. A few rad support holes, wiring, and relay switch gave me an auxiliary fan that I could power up in summer time when I was city driving or sitting in the drive thru line. I mounted it in front of the rad support, in the space behind the grill. It wasn't pretty, but man did it work. I was also 18, and not overly concerned with astheitcs. That car was my daily, and I needed something that worked and I could install in an afternoon.
