Overheating at idle

OP, this was answered correctly in post 9.

You need to over drive the water pump. And the fan. Low speed cooling issues are usually a water/air issue.

If CVF has a 20% over driven pulley set please post up the part number.

I’m at 6% over right now but I would gladly go 20 over.
CVF serpentine kits as mentioned have 6.4" Crank & 5.3" Water pump pulleys. Their V belt pulleys are 1:1.
Part #'s as follows:
360-SERPENTINE-ALT (Alternator only)
360-SERPENTINE-PS (Power Steering)
360-SERPENTINE-AC (AC & PS)
These are polished. Prefix with B- for what they call their stealth black finish.
