only stats i can find to run in my fresh sbc 355 is 160, 180, 195. now i already have a 160+195 but can't decide on which to put in. still got stockish water pump, best new hayden fan clutch, and the stock 3 core radiator flushed. probably switch to an electric fan next year. whats everyone run in theirs? oh yea, i'm up in the dakota country but car won't be driven in winter except as a last resort.
