The native search feature can be tough, try adding "LS1tech" to the end of a google search. "Huron Turbo Drains LS1Tech"
No pics but I used -10 AN line w/ a 90 off the turbo ran to the oil pan and tapped into the pan 1" below the pan rail above the drain.
Never had any issues with oil backing up unless I was breaking on a down grade like a highway off ramp at speed, even then only very little smoke.
I'd suggest 1/2" or 5/8" hardline if you can swing it, straight to the front of the pan or timing cover, you of course want some slope to it so oil doesn't back up.
It's pretty straight forward, good crank case evacuation is key as well, a good PCV catch can system is highly recommended, the Mighty Mouse PCV can worked well for me.
