V6 to V8, installing OEM dual fans, what temp on/off for switch?

Ordering a fan relay/temp switch/harness install kit and there are many different combos.

83 Firebird with a 350 swap. Running OEM TPI dual fans. Basic setup.

I'm up in New England so most days aren't going to be scorching.

Car isn't driven in the winter.

Won't be seeing much racing, just daily use for the most part.

Options for fans on: 176/180/185/195/210

Options for fans off: 161/165/170/175/190

Was thinking this one: http://www.summitracing.com/parts/sum-890014/overview/


Thoughts?

IMHO,

I'm thinking anything less than 185* is too cold, won't even really let the engine reach operating temp. I'd personally go with a 190 on, 175 off or even a 205* on, 180 off.

Ok cool, that's exactly what I needed to know. Wasn't sure where the old 350 was happiest!
