It seems with any swap there is lots and lots of research. Actually one part that I really like. The LS3 AC compressor has the line exit direct into the frame rail so that wasn't going to work. I happen to have a truck bracket and come to find the LS3 has the same belt spacing as the trucks....
Tried a couple different truck compressors, no go... lines again exit directly into the frame rail.
Thought about using the stock s50 compressor and make a bracket. It would be nice to use the stock lines. It does "fit" but sits about 2" further back than stock so the lines really wouldn't work anyway.
A couple pictures of how it fits.
Belt lined up
I really wasn't too happy with that so started digging. I use google images a lot to find things...seems to work the best for me and is the fastest.
I found a bracket to use a sanden compressor on the LSx.....like this. I THINK the lines will clear the frame rail from all my measurements. If not there are different sanden compressors with the lines that come out the back.
Some more digging and I found that the trailblazer/enovy has a different AC compressor than the other trucks with the LSx engine.
The compressor has the outputs more on the TOP..... looking like this might work.
I have a compressor coming tomorrow to see if that will fit. Looks like the bracket can be bought new from GM for around $25.
A few pictures of that setup...these are not mine.
It fits great. I'm not sure if I will keep this exact compressor as it is painted black. New rebuilt from the parts store but just looks out of place not matching the engine. Gotta see what else I can find. But this type works for sure with the LS3 belt spacing or truck for that matter.
Line location
Clearance to rail
From the front...uses a truck tensioner
Here is the bracket.
LS3, truck, trailblazer. I will have to drill a hole or weld an ear to the back for the lower hole as the LS3 mounting is a little different. Top bolts are the same and everything lines up tho. There is even a cut out on the back of the trailblazer bracket where a hold could be.
I was hoping to make the trans mount and start on headers today but I come to find that there is no rubber mount on the tr6060. drat! I have a rubber mount on the way.
Either way...lots of other things to work on.
Brake and fuel lines....powder coated...calipers will be coated to match
Clean tank ready to go back in
Straps with new pads
Tank is back in
Just some random pictures now that it is raised up.
