INSTALLATION PROCEDURES:
This mount kit is designed as a weld-in application. Cutting, grinding, and
welding is required. These mounts should only be used when replacing a
stock 6 cylinder engine. Jeep TJs with a 4 cylinder engine must use Part
No. 713090, which is a bolt-in mount. If this kit is used with a 4 cylinder,
the steering pillow block must be modified.
To install a Chevy V8 into a Jeep TJ, we recommend that the entire front
clip of the vehicle be removed for ease of installation. This would also
include the hood, grille, both fenders, and miscellaneous components.
Some of the components in the engine compartment may need to be
relocated (i.e. smog equipment, battery radiator, overflow, etc.). Once the
stock engine has been removed, you're ready to begin the new engine installation.
OPTIONAL ITEMS:
717090 Headers
716691-AA RADIATOR
716693-AA RADIATOR
714450 1"BODY LIFT
If you are using an aftermarket
oil pan, the maximum depth in
the front is 3-5/8". NOTE: This
motor mount will not work with
383 Stroker motors or 400 S.B.
Grind or torch off the stock frame mounts. Grind off all the welds, and make the frame rails smooth. Next, identify
the holes on each side of the frame which you will use to locate the mounts. They are located on the inside of the
frame, about 23" away from the front crossmember. Using the bolt that protrudes from the frame mount as a

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.

alignment pin, C-clamp the mounts to the inside of the frame (the front-to-back angle of the mounts will be determined
later).
Install the new Chevy rubber mounts onto the engine block and install the saddle mount. As you set the Chevy block
into the TJ frame rails you'll notice that you will have about an inch window for front-to-rear mounting options.
Place the engine in the engine compartment. The forward-to-rear location of the engine is to be determined by you
and by the drivetrain you have chosen. Also, keep in mind header or manifold clearance when positioning the engine.
When a suitable location is found, rotate the doweled frame mounts so they hit parallel to the engine saddle mount
mounting flange. Tighten the C-clamp and/or tack weld them in place. The frame brackets must also have two holes
drilled for mounting to the saddle mount. Before removing the engine, mark the two hole locations on both frame
brackets where the saddle meets the frame brackets. These holes need to fit a 3/8" bolt. Remove the engine
assembly and fully weld the mounts to the frame, then drill the mounting holes.
Both the driver's side and
passengers side firewall to
tunnel seam will need to be
cut or folded over for both
transmission and exhaust
clearance.
Headers will require firewall modifications in the furthest back location, but work great in the forward location. Also,
the passenger side header may require some clearance with certain starters (on solenoid housing). A heat shield and/
or a mini hi-torque starter is recommended.
P/N 717090 headers installed.
