[67 Nova Boy]

I was running a clutch fan when I fired my 302 up and it hit 260 in 10 minutes. Had to shut off {During break in of motor} and installed a flex fan and right down to 180 deg. Ran there for 10 years with 180 stat. I ran 4:11 and after 3,800 rpm the car would run at 200 deg doing 70 mph. Drop down to 3,300 to 3,500 and back at 180. Never mattered the outside temp...it still ran 180. Drove to Super Chevy last year when it was 90 and humid out and ran 180. My temp sender is in my passenger head so it might be cooler yet?

I run a wild cam {560/560 294 Soild} and runs cool. Try a flex fan as Sam says!! He knows this stuff!!!
