I'm a child of the 70s, and loved Corvettes when I was a kid (until I discovered Car and Driver magazine, and learned about krautwagons....). There are oceans of clean C3 Vettes floating around, especially the later 70s. I know the cars got slower and slower because of emissions baloney as the 70s went on, but power output aside, are they enjoyable to drive? It would seem like a pretty easy job to drop in a hotter crate motor.
