Re: Hot-running LS6
190 to 210 isn't unusual for these cars. If I recall correctly the OE thermostats were in the 185-195 range. I replaced mine early-on to bring the temp down.
We attended the Street Machine Nat'ls the year it was held at Gateway in E. St. Louis and were trapped in the gridlock trying to leave on Saturday afternoon. My battery wasn't doing well and I was afraid the car might not restart so we let it idle for over three hours. The car never once got above 165. That was with Turbo Blue in the tank and timing at 2 degrees advance. Yes, timing can be a factor.
Another thing to check out is your water pump. I have a friend who built an L-88 for his '69 Chevelle and had similar trouble. He installed a new four core radiator but still no help. Finally tore into the water pump and found the fins on the impeller were about half the size of the ones on the other pumps he had used. Changed pumps and the problem was fixed.
Just some thoughts. [img]/ubbthreads/images/graemlins/dunno.gif[/img]
