straight six's are some of the toughest motors out there, ford gm or chrysler. just as long as your temp doesn't get above 200-210 you should do good. my 350 if i just let her sit and run she runs to 200 then the fan kicks on. driving she usually runs at about 180-190. but 190 is perfectly fine for a motor. actually i think that's what the factory thermostats are. i wouldn't be too concerned until your motor hits about 205/210+ in temp.
