rb ... decent voltage, that eliminates that as a problem. It looks like you're close, if not there, to curing your cooling woes. It would appear that the new upper/inlet shroud has helped by reducing "superheated" air recirculation and the fan shroud has produced a more uniform, all core encompassing, pull across the radiator.

I got my 140 amp chrome Powermaster the other day from Summit. It came with a 4 gauge wiring harness for battery/alternator connections. That will help me do better than 10.9 volts at the fan.. I'm waiting for the 6 3/4" lower pulley to complete everything I need. I've got to install the alternator, new "high flow" 180 deg t-stat, water wetter plus all the wiring I've got to redo. If all that doesn't produce the results I'm looking for then I'll re-evaluate my fan/shroud thinking and also consider doing the top shroud boogie..
