Timing's just fine, I still need to fabricate the shroud. The main reason I was doing this test is to be sure the clutch was operating properly before I go through the trouble of fabbing up the shroud and just having to take everything apart if something wasn't operating correctly. Also, I did have a dual electric fan setup before but cooled inadequately; pos aftermarket thin fans, it's really no surprise why it likes to overheat at idle.
