If you do go to a mechanical fan, make sure to run a shroud and a clutch type is what I'd go with. A stock clutch fan for your truck should do the trick. I run a 4 core BBC copper radiator in my 72 K30 and have a 180* thermostat in my engine. Mine runs around 193* in the summer. I don't even have a fan shroud on it yet.

Your condenser should be in front of the radiator support and the radiator is behind it. The stock condensers had the core set ahead about an inch but the mounts bolted flat on the support. It might be worth spacing your condenser forward a bit to see if it helps.
