BBC Early Serpentine Conversion Kit - K10014

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
GM 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) -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)

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.

Consider our Gates replacement Water Pump: (Kwik Performance
PN 44030).

A big-block crankshaft pulley, GM part
number 10085753 (usually retails for $150+)

Solution: We have developed an adapter
to let you bolt on the SBC crank pulley from the donor engine.

Consider the Crank Pulley Adapter for BBC engines (1966-93):
(Kwik Performance PN K10259).

Consider the Crank Pulley Adapter for BBC engines (1994-2000):
(Kwik Performance PN K10540).

Donor engine didn't come with crank
pulley? We've got you covered: SBC
Crank Pulley: (Kwik Performance PN 10085754).

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.

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!

34152).
