Hi Phil Wow.. I would think just the opposite to be the fact... with the lower temp Stat reaching open state at 160 deg. once the entire volume of coolant reaches the medium stat temp of 160 deg.. It would just continue to climb in temperature... and the 180 deg with it's delayed opening . would let the fluid have a chance to dissipate heat in the Radiator !! Being a early Chevy nut my First BB was in a 55 Chevy post care.. a 454 with a corvette tri power.. . it was not until I discarded the vertical flow radiator and went with a modern cross flow was I able to keep the big rat coooooool. My SB in my chevelles are not ground ponders warmed over 355's but HEAT is a problem ... Especially when caught in bumper to bumper Traffic...I run 4 core desert coolers modified after market repop 66 BB fan shrouds and LARGE fans
Herb has the answer , with his trick set up. Big Aluminum radiator with dual electric fans.. SWEET ! But the real issue is to keep the fluid temp B low the State temp in the Radiator . a quest most of us early chevelle guys have to deal with .... not trying to be a wisy A** just surprised by your results..

What thermostat were you running at 190-225. A 180? Did you change to a 160 during the warmer months? I've got a built SB and have to switch back & forth. The 160 runs about 170 normal and around 210 if caught in traffic. The 180 will run around 190 and push 225+ in traffic. That makes me nervous. This is not a daily driver. But sometimes to shows & home you just get caught. It happens!! Just wondering what your experiences are since you mentioned cooling problems. Just a note-running Edelbrock aluminum heads on my SB. Always looking for advice & ideas re cooling.
