Big Block Chevy Serpentine Belt Conversion Kit
Kit contents:
Plates attach to the three accessory holes on each head and to the two pairs of
holes on either side of the timing chain cover on the block. Long bolts go through
the brackets and plates and thread into the outermost holes on both cylinder
heads.
- Seven high quality 6061-T6 heat-treated aluminum adapter plates,
produced by computer controlled ultra-high-pressure water jet. - All nuts and bolts to attach the adapter plates and GM brackets to a big
block Chevy engine. Note: Both 3/8 and 7/16 bolts are included for the
passenger side head, since the holes vary for different years. - Instructions with diagrams and pictures
- Driver side and passenger side aluminum drive brackets off of a 1990-1994
Chevy 350 truck V8 or 4.3L truck V6 , with casting numbers 10118701
(driver's side) and 10118751 (passenger side). These are the brackets
shown below. Notice that the passenger side bracket does not have an arm
for mounting an air pump. Passenger side brackets for an air pump can be
used as long as the idler and tensioner are positioned as shown below. Also
notice the zigzag pattern ribs at the top of the driver's side bracket under
the alternator. These brackets were used for other years and models too,
including many V6's. A salvage yard or GM dealer may be able to help find
them. See pictures. The passenger side bracket should include the idler
and tensioner. - Air conditioner compressor and pulley, alternator and pulley, and power
steering pump and pulley off the donor engine. Note: A good reason to use
a 1994 compressor is that the compressor will use R134a refrigerant. - A water pump pulley off the donor engine. Do not use a pulley with a
groove. The belt surface must be smooth. GM part number is 10085760. - 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. - A big-block crankshaft pulley, GM part number 10085753.
- Gates belt number K060966 or equivalent 6-rib 97 1/8” belt. This assumes
the use of the brackets listed above and the belt routed inside the idler as
shown. If the idler is not used, a 96” belt should be used. 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
Plates attach to the three accessory holes on each head and to the two pairs of
holes on either side of the timing chain cover on the block. Long bolts go through
the brackets and plates and thread into the outermost holes on both cylinder
heads.
