Will a Black Magic Fan cool a 331?

[302 LX Eric]

My new motor is a 331 cu. in. stroker with ported TFS TW heads, Steeda #19 cam (.516/.516 w/ 1.72's), 9.2:1 compression, GT-40 intake, Accufab 65 mm TB, 75mm Pro-M, 24# injectors, 155lph pump, 3.55's, Tremec, etc.

Currently, I'm running a 195 thermo and Griffen radiator. Under hot and humid (say 90* and 80% humidity) conditions, the car runs right at 185-190 on the Autometer gauge - all while moving at any decent speed. However, at long stops, drivethroughs, etc. the temp will SKYROCKET to 230* in a matter of minutes. The car never did this with the old 302 motor. I know I've got a ton more torque and power, but is this what's causing my overheating issues?

I was going to step down to a 180 thermo, but was thinking maybe I should just free up some HP by gettng a Black Magic setup. However, after a topic search, I've noticed that the Black Magic fans don't seem to cool strokers too well or 351's for that matter.

So what would you guys recommend? Should I get a dual electric fan setup? Get the Black Magic and 180 thermo? Stick with the stock fan and get a 180 thermo?

Thanks in advance for the replies.

BTW - I'm running a 70% distilled water & 30% Prestone mix - no water wetter, yet.
