Any pics of the other side of the stat? No issues with fitment between LS7 and LS3 and just position the air bleeder same orientation? You may need to consider fan tuning. I do see my temps drop when AC cycles at 60mph. I'm assuming fans kicking in since temp drop dramatically at cruising RPM, then they go back up to 190. Not sure how it would operate at track speeds. Since my street temps rarely go over 200 and I'm usually in the mid 190s on the high side, only time I notice fan kicking in fully w/o AC is cool-down between runs at auto-x. Stupid KB Supercharger coolant reservoir starts overflowing.
Interested to see if they make a difference for you on longer track sessions.
