NOTE: When using this kit wit our bellhousing kits 712567V or 712591V , you will be required to use a special st arter P/N

22-0002. The "V" bellhousing kits have a modified release arm and spacer for the slave cylinder that must be used to work
with the LS series blocks.

GENERAL INFORMATION:

Since the LS series flywheels only fit a LS series block and the engine crank is recessed .400”, there are a couple of things
that must be addressed. Usually our bellhousing kits include a new pilot bushing. A problem occurs because of the 1.090”
diameter that our bushings fit into on a standard GM is now .400” closer to the back of the block, creating a pilot bushing
engagement problem. This kit comes with a pilot bushing spacer for the manual transmission applications. The spacer in this
kit sets the pilot bushing in the correct location. NOTE: The grove on this bushing must be facing out when installed into
the engine crank.

OPTIONAL ITEMS:

P/N 716286 is a bracket that fits

our NV4500 full bellhousings.

P/N 716213 slave cylinder fits this

bracket.

P/N 717514 Stock manifold collec-

tor rings and gasket kit.

Warning: The clutch parts included in

this kit will
flywheel included in this kit.

only work with the custom

The second issue is the flywheel. The flywheel in this kit only fits the recessed crank and bolts to the crank without a
flywheel spacer. There are some LS series blocks that do not have the recessed crank. This kit will not work on these
blocks. One block that we know of is the 6.0L with cast iron heads and the 4.8 engine coupled only to a stock manual

transmission in 1999 to 2003. A custom flywheel would have to be made to work on these block.
The pressure plate and clutch disc are also included in this kit. These components are specifically designed for the LS series

engine. The bolts have also been included to allow proper alignment of the pressure plate to the flywheel.
The release bearing in this kit is a custom bearing. When coupled to a stock transmission, the LS series engine used a internal

release bearing. Our full bellhousings are not compatible with the stock internal setup. This bearing design is manufactured
to replace the internal bearing with a conventional bearing setup. Do not use any other type of release bearing with this

conversion. Premature clutch failure could occur.

On Ford and Jeep transmissions, our bellhousing kits normally use a stock release bearing. These bearings have a 1.43" I.D.
and fit the transmission retainer snout. This kit comes with a new bearing that has a 1.37" I.D. If using this kit with a Ford
or Jeep adapter kit, you will need to machine the retainer snout to fit the new release bearing.

SPECIAL NOTE: The components packaged in this kit have been assembled and machined for specific type of conversions. Modifications to any of the components
will void any possible warranty or return privileges. If you do not fully understand modifications or changes that will be required to complete your conversion, we strongly
recommend that you contact our sales department for more information. This instruction sheet is only to be used for the assembly of Advance Adapter components.
We recommend that a service manual pertaining to your vehicle be obtained for specific torque values, wiring diagrams and other related equipment. These manuals are
normally available at automotive dealerships and parts stores.
