Made its first trip to my "new" job, and didn't have to drive or park on dirt! It gets warmer in stop and go traffic, but that is expected when there is no airflow across the radiator. When I get a VSS hooked up (like with the 4L60e swap) I'll probably have the radiator fan come on at 190ºF and below 20mph instead of just over 205ºF and no speed criteria. It never actually broke over 195ºF, but it's something to watch.

Anyone ever make a heat shield or such to help separate the exhaust manifold heat from the intake?
