you have the correct distance between the fan and radiator for a set up that does not use a shroud. If you go to a fan shroud, which may or not help, the center of the fan blade needs to be half way into the shroud opening for the best cooling. to far forward, or back will hinder cooling. What thermostat are you using, and what was the ambient air temp. when you were running 200*F ? 200*F is a bit on the warm side, but not really any thing to get worried about unless it runs hotter when running it a little hard. it may be that the eng. is just tight with a fresh rebuild. I have heard of cases where some 289/302's have run hotter when bored more than 30 over, but have not experienced it myself. I once had a 260 bored 30 over, and it ran 180, with a 180*F thermostat all day.
