I just looked at one of the review's on summit racing from the link you sent me, they put a picture of it mocked up on their Camaro. Name plate read SD7B10. Unfortunately that's a 100cc/rev compressor. My opinion, way too small for what you're trying to accomplish. Do you know if the Trailblazer SS is the same offset crank pulley as a standard truck drive?
