March BBC SWP Blowers Tune Port


Chevy Big Block serpentine kit for super charger tune ports


CHEVY BIG BLOCK SERPENTINE DRIVE
"High Mount" A/C & Alternator Serpentine Kit For Multi Carburetor, Super Chargers, Tune Port


Available in Deluxe and Custom Styles, Deluxe style has idlers and belt routing that provides extra clearance for multi carburetors, super chargers and Tune Port applications. Lower cost Custom kit incorporates a compact combination alternator /air conditioner bracket for single carb applications. These bracket kits come complete with stainless steel tensioning rods and chrome moly rod ends for high performance operation. All necessary hardware included. Powder coated to eliminate polishing in those hard to reach places. Matching serpentine pulleys are precision CNC machined from 6061-T6 aluminum. These pulleys will not fracture like common cast pulleys. High tensile strength means much longer wear. We go as far as hard coating the high wear areas on our high water flow ratio pulleys! Our street rod ratio increase water flow and fan speed. This helps at critical low speed driving. All pulleys have a maintenance-free clear powder coat.

Application:
This kit fits 1957 and earlier cars and full size trucks. 1957 and newer cars check for hood clearance. Edelbrock #8884 and #8864 water pumps use cast iron water pump kits. For 9.8" deck height blocks.
