get rid of the flex fan. it only works good at high rpm.
go electric fans for the best outcome.

Try to find a speed shop that sells 40 BELOW. It's a coolant additive that drops the running temp tremendously. I run a bored and stroked 454. It ran on average 230-250. After I added it, it runs 195-220. Be sure to read the directions and warnings first, you cant mix it with some types of coolant. Just trying to help.

I would also check the t-stat,or just change it to a 180*.

A fan shroud will work wonders, if you don't have one. Even if you are using an electric fan only, you need a shroud. My last BB wouldn't stay cool for anything. I used water wetter, 180* thermostat and a 2250cfm electric fan and it still wouldn't stay cool. As soon as I installed a shroud, the temps are where they should be.
