I'm thinking about making the complete LS1 swap, I already got the tranny for it, and I was wondering what I would need to make the A/C from it work with the original heater control panel with A/c if I swapped that in. Right now my car doesn't have A/C so I'm making a total conversion, minus the compressor that is on the LS1 correct? Thanks ahead of time for all the help.

You might want to do search for Vintage Aire (sp). I think that is the way I'd go for AC.

I'd like to do the LS1 swap. I'm on the look out for one.

Here is a basic overview by an individual that has done a swap.
