Camaro mustang nova fast car?
Whatever you do you will need to take a good look at the cars you are considering. 5 grand is a lot to spend on that kind of car, so you should be able to find an excellent example. I would go with whichever on is the best deal. A 350 is a great motor, but you should stay away from the throttle body injected versions, as well as any throttle body injected chevy, the heads are crap and, you will never be able to build power. The tuned-port Irocs would be a great car to have. Have fun.
