GENERAL INFORMATION:
This engine assembly is built with current production 5.0L H.O. crankshaft, rods and pistons, resulting in a 50 oz. external
balance requirement. The damper & flywheel included are compatible with this balance specification. The damper and
flywheel combination for your particular installation may need re-balance or some other modification for compatibility.
(See #4 & #5 for more details on balance). This engine is intended for off-road applications and can be adapt ed to most
289-302 situations.
THIS LONG BLOCK IS FOR OFF-ROAD USE ONLY AND DOES NOT HAVE A WARRANTY

PARTS REQUIRED TO COMPLETE THE ENGINE:
Water Pump and Plate:
The front cover and water pump supplied are for a reverse rotation serpentine style system. Some serpentine
systems may also require a different timing chain cover and water pump. A V-belt system may require a different
front cover to use your standard rotation water pump.
Distributor:
Must be equipped with a steel drive gear for roller camshaft compatibility. Can be Duraspark or EFI depending on
vehicle applications – use 1-3-7-2-6-5-4-8 firing order.
Intake Manifold/Fuel System
Just about any intake produced for 289-302 applications will fit GT-40 heads. Water transfer hole design was
enlarged in 1976 on all applications. Pay attention to intake gasket fit. A Performer RPM or RPM Air Gap intake is
suggested when using a carburetor. A GT-40 or Cobra intake is suggested for EFI. Suggested carbureto r size
600-650 cfm. The suggested injector size with M-6007-B50/B51, is 24 lbs. The suggested injector size with
M-6007-XE3/XB3, is 30 lbs.
Front Accessory Drive
Must be selected for your particular application. Since drive alignment begins with the damper, note that the 50
oz. damper supplied may not work with your application.
Flywheels
The engine is supplied with a 157-tooth (13-1/2 dia.) manual shift flywheel using the 50 oz. balance factor. This
flywheel will accept a 10-1/2” diaphram style clutch. It can be re-drilled for a long style pressure plate. If your
application requires a different flywheel (C-6, C-4/A.O.D./or 164-tooth stick) call the Tech Line at (586) 468-1 356
for the correct part number and application.
Valve Covers
The GT-40 is shipped with current level valve covers for top end protection. These units have no provision for the
PCV system or breather caps when used for non-fuel injection applications.

PRIMING THE ENGINE LUBRICATION SYSTEM:
! ! ! WARNING: DO NOT ATTEMPT TO START ENGINE WITHOUT FILLING THE CRANKCASE WITH OIL AND
NOTE: Prime the engine oiling system before the engine is installed into the vehicle.
STEP 1: Fill the crankcase with (5) five quarts of 10W-30, 10W-40 premium motor oil.
STEP 2: Tape a ¼” deep well socket to a long extension.
STEP 3: Insert the socket/extension combination into the distributor opening on the engine block.
NOTE: The socket extension combination must engage the oil pump intermediate driveshaft.
STEP 4: Rotate the socket/extension combo counter clockwise until oil flows from the pushrods.
NOTE: A reversible electric drill is recommended. Check pushrods for oil flow.
STEP 5: After oil flows from the pushrods, remove the socket/extension combination from the distributor opening.
DISTRIBUTOR PREPARATION/INSTALLATION INSTRUCTIONS:
STEP 1: To install the distributor correctly, the #1 piston must be at T.D.C. (Top Dead Center), with the intake and
exhaust valves closed.
! ! ! CAUTION: THE DRIVE GEAR ON THE DISTRIBUTOR SHAFT MUST BE STEEL OR DAMAGE TO THE
Note: With distributor cap installed, locate the #1 post and place a mark on the distributor base.
STEP 2: Rotate the distributor shaft so that the blade on the rotor is to the left of the mark , but as close to the
STEP 3: Install the distributor into the engine block opening. It may be necessary to slightly rotate the rotor/shaft

STEP 4: Verify rotor blade is pointing at #1 mark on the distributor base.
NOTE: If the rotor blade & the magnetic pick-up cannot be aligned by rotating the distr i butor
in the engine block, remove the distributor enough to disengage the distributor drive gear from
the camshaft gear. Rotate the rotor enough to engage the distributor gear on another camshaft
gear tooth.
STEP 5: Repeat STEPS 3-4 if needed.
STEP 6: Install the distributor hold-down clamp and bolt. Tighten the bolt, but leave it loose enough to rotate the
distributor.
STEP 7: Install the distributor cap/wires.
STEP 8: Set the timing. Tighten the hold-down bolt.
INTAKE INSTALLATION INSTRUCTIONS:
STEP 1: Check the gasket fit on the heads and intake. Install the gaskets/silicone to the block and heads.
STEP 2: Carefully install the lower intake. Start the intake bolts, and hand-tighten.
STEP 3: Torque the intake manifold bolts, in sequence, to 10 ft./lbs., starting with the center bolts, working out
towards the ends, while alternating from side to side.
STEP 4: Repeat the same torque sequence using 18 ft./lbs. The maximum torque on aluminum heads is 18 ft./lbs.
CRANKSHAFT DAMPER BOLT INSTALLATION INSTRUCTIONS:
STEP 1: Check the crankshaft damper bolt. It must be torqued to 70-90 ft./lbs.
! ! ! CAUTION: THE CRANKSHAFT DAMPER BOLT MUST BE TORQUED CORRECTLY TO PREVENT DAMAGE
