Cooling a 351..electric vs. mechanical......what the best product?

pn 175 is the one youre using and the one im taltking about. 2800 cfm's of air is good . ive never had a problem with them on my cars. like i said, there are other variables though. if youre using a pulley set then your temp will rise a little. if you have serpentine belts and you put the belt on the wrong side of the pulley it will run 20 hotter. if timing is high it will be hotter. i would try checking everything else first since it is free and easy. changing the fan may not help.
