VORTEC GEN. III V8 SQ. BOLT
TJ WRANGLER MOTOR MOUNTS
Engine Installation:
* For ease of installation, leave the engine motor mount brackets off until the engine is in place.
* The Vortec engine is very large. Firewall modifications are minor, yet mandatory.
* A trial run is highly recommended.
* The engine and transmission should be bolted together for an easier installation.
Using an approved engine
hoist, lower the engine into
the compartment. Pay atten-
tion to the exhaust manifolds
and the radiator (removing
the radiator is a good idea).
The engine may not slide fully
into the compartment due to
firewall interferences (check
the clearance on both the
driver’s and passenger side
around the engine heads and above both of the exhaust manifolds). Mark
these spots with a pen, remove engine, and clearance the firewall accordingly. Lower the engine back in and check the
clearance. Using the supplied hardware, attach the engine mounts to the block.
Take the four large 1/4” spacers (2 per side) and trial fit them to get a comfort-
able front-to-rear engine placement. These mounts have up to 1/2” movement
front-to-rear to account for any differences in frame locations and to “fine
tune” engine placement. Use the 1/2” bolts and nylon nuts to secure the engine
to the frame. Bolt the steering pillow block assembly to the mount. Take a
quick look around the engine and steering to make sure there are no clearance
issues. You should have just enough room to fit your hand between the engine
and firewall/frame.
Vacuum Connection for Brake Booster:
You will notice that the Vortec block has no provision for a vacuum line for the brake
booster. There is a small port on the back of the intake manifold that can be used. First,
pull out the black plug on the intake manifold by holding pressure
on the gray ring. Once the plug is out, drill and tap the black plug
for a 1/8” pipe thread. Use a 90 degree 1/8” pipe by 3/8” barb
adapter and thread it into the tapped plug. Press the plug back into
the manifold and attach the hose.
