We hit the floor at SEMA 2015 to find the shortest possible serpentine drive system for the LS engine, and we found it! This innovative system made by Zach from drivejunky.com mounts the A/C compressor down low, therefore allowing all the pulleys to be moved back further. Perfect for fitting an engine like ours into your muscle car. Our turn key engine packages come with these high quality drive systems configured to your needs.
