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.
