pcv and thermostats for street strip cars ?

Have you thought about just a simple catch can? I'm using a home-made one on the 440 in my Chrysler. Stops alot of stuff getting back to the carb from the PCV. The 340 in the Duster doesn't seem to need it, but it is a pretty mild build as far as I can tell.

As far as thermostats go, I can't figure out why people keep talking about running these cool stats - 160-180. Why not run it at a nice efficient 190 or 195 if the rad and rest of the cooling system is up to it? I run a very small plastic fan on the Duster that keeps it down to about 210 in stop and go traffic, 95 degrees ambient. I think I could get away with no fan at all if it wasn't for the summertime temps around here.
