One thing of note is that for 2019, J55 brakes are only available in the YQ4 Heavy-Duty Cooling and Brake Package. That includes (KC4) external engine oil cooler. So, this is likely the same cooling that the LT1 will have.

Also, this information is subject to change since GM has not released the order guide yet. This will help those of you with questions though.
