radiator baffles
i agree with chris. The upper baffles and lower air dam are critical as well
as water pump clearancing and good HD fan clutchwith & blade fan.
my car with 180 stat this weekend never broke 190 except when I was stuck in traffic after getting off highway. Climbed and held at 195(highest) and dropped right to 185 once moving again. I am running the factory style 3 row radiator.
water pump pump pulley size is a player too. Mine takes longer to heat up with the
smaller 6" pulley but also cools better.
