05 CTS V 07 ESCALADE
Just a FYI on a recent track outing where I got to really work out the motor. With about the smallest Mocal cooler 13 row 325 Matrix, temps never exceeded 230. That was with long fast 140 mph straights at Road America with lots of operating at the upper most rpm ranges on a 420 rwhp LS6. I was worried the cooler might be to small but so far it's getting the job done.
