Conor Sheffield’s ’39 Chevy rat rod is completely home-built, packs 6-71 supercharged LS power and even rocks an AC system to keep it cruising even on scorching desert days. The chassis is fabricated from square-tube steel and the factory sheet metal features a 4in chop. Sheffield adapted a 6-71 blower to a Holley Hi-Ram intake, controls it with a Holley EFI Terminator X ECU, and a bolt-on Holley LS mid-mount front drive tucks all of the accessories, including the AC compressor, neatly between the frame rails.
