Automan, all of the suggetions above are right on.

I have a FE motor and live in a very extreme hot climate (AZ), so over heating was a bit of a problem for me too.
I built a fan shroud with a puller fan (two fans -pusher & puller counter act each other). Installed a 180 thermostat, drilled it, installed a recovery system etc...still ran hot in stop & go traffic.

Guesswhat, the gauge was bad, new gauge indicated perfect temp. control..never over 205 in stop & go with ambiant temps at 115 degrees.
I found the true problem using an infered tool that checks actual temps anywhee you want to check it. $35.00 in the Summit book.
Anyway, best of luck...Bill
