What’s included:

Adapter plates made of 6061-T6 aircraft grade aluminum (brushed satin finish)
CNC machined crank pulley adapter
Zinc coated fasteners

     -Bolts for adapter plates AND to attach OEM brackets included

     -Both 3/8 and 7/16 bolts are included for the passenger side head, since the holes vary for different years

What else is required to complete the installation:

GM BBC engine (1966-1993)

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)

A reverse rotation water pump off of a 1988-1999 454 engine.

A small-block crankshaft pulley (from donor vehicle)

Six-rib belt, See our included installation instructions for suggested lengths and Gates part numbers.

A new thermostat housing may be needed to allow the upper radiator hose to clear the alternator.

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!
