I run the biggest coolers I can fit, bend my own steel lines and hide the cooler up front where it can't be seen. The only clue is seeing one of the trans lines from the radiator disappearing under the core support and going to the front, and another line running to the back along the stock routing with the other line.
If done properly one really has to look at it and pay attention to even detect an extra cooler.

The Olds diagram you found gives you the idea. Modify as you see fit
