I'm wondering how ya'll have configured your cooling systems with the LT1 swap. I'm not having any issues but i'm looking to make it look a little better. The factory used a hard metal line that ran along the frame rail and went strait to the radiator and routed the hoses differently. The LT1 doesn't use this so I'm curious what options are out there. Currently, i'm running hoses from my LT1 water pump to the heater core, with a T fitting that goes to the steam tube. Any pics would be great.

 

You can use the 4th gen heater core hardlines for a cleaner look, but most swaps LT1 and LSx use common hose from the WP to heater core

Check the upper radiator port that used to be for the heater core. Some are threaded internally and accept a 3/8npt barb for the steam line
