What’s included:
  • Adapter plates made of 6061-T6 aircraft grade aluminum (brushed satin finish)
  • Zinc coated fasteners
    • Bolts for adapter plates AND to attach OEM brackets included

What else is required to complete the installation:
  • GM BBC engine (1966-1993) -or- (1994-2000)
    • 366, 396, 402, 427, 454, 502, 572
  • AC and Alt/PS aluminum drive brackets off of a GM Truck engine listed above.
    • The brackets should include the idler and tensioner.
  • Air conditioner compressor (from donor vehicle)
    • Note: A good reason to use a 1994 and up compressor is that the compressor will use R134a refrigerant.
  • Alternator (from donor vehicle)
  • Power Steering Pump(from donor vehicle)
  • A smooth water pump pulley is required (GM part number 10085760 or 19418445)
    • Donor engines should have the correct pulley. (The pulley with flanges does not work)
    • View the Water Pump Pulley: (Kwik Performance PN 19418445).
  • A reverse rotation water pump off of a 1988-1999 454 engine.
    • This is considered a "long" pump and is 7 5/16" from block to fan mounting surface.
    • View the Gates replacement Water Pump: (Kwik Performance PN 44030).
  • A big-block crankshaft pulley, GM part number 10085753 (usually retails for $150+)
  • Six-rib belt, See our included installation instructions for suggested lengths and Gates part numbers.
    • Alternator rating and PS pulley diameters can change suggested lengths.
    • Always check tensioner marks for correct fitment.
    • A tall deck engine will require a belt that is about 1" longer.
  • A new thermostat housing may be needed to allow the upper radiator hose to clear the alternator.
    • The Chevelle shown is using a swivel-neck housing.
    • Upper radiator hose will probably need to change, but your vehicle's stock big-block lower hose, should work.
Don't want to run AC? Here is the adapter to do that!
  • View the SBC AC Delete pulley: (Kwik Performance PN 34152).
