Swapping those cooling systems are harder to stomach because it's more work and you may be voiding warranties on a brand new car.

I was going to make a similar comment. Also I think the LT1 front bumper doesn't have the internal air channels that feed the auxillary radiators even if the aux radiators were added.
My M6 SS 1LE reaches max oil temps in the 260s to 270s (°F) on track. I think the LT1 would probably overheat on track if driven hard with the coolers it is missing compared to the SS & SS 1LE. I think track use also voids the warranty on the LT1 if I remember correctly.
I'd recommend just bringing the car to autocross in stock form to try it out before doing any mods. Consider turning traction and stability control fully off if there's nothing solid around that you could hit if you spin out.
