The universal design of our alloy intake manifold supports Holley, Autolite, and Weber 2V/4V carbs, with the proper carb adaptor. It features high velocity intake runners with a raised rib design for that classic look, injector bosses for fuel injection capability, and water ports for heating & cooling. Includes your choice of carb adaptors (shown below), stainless steel hardware kit, and our custom gasket set.

Note: Our alloy intake manifolds will not fit on a stock OEM log style cylinder head. The stock cylinder heads have an integral log intake manifold that was cast as part of the cylinder head, as such the stock log intake manifolds are non-removable. Our alloy intake manifolds will only fit on our Aluminum Cylinder Head or the Australian 250-2V cylinder head. However it should be noted that the ports, particularly the third and fourth ports, need to be port matched for optimum air flow when used on the Australian 250-2V cast iron heads.

The injector pads, which can be used for EFI or NOS, need to be machine by the customer if they wish to install injectors in the intake runners. The pads can also be used to install throttle cables, carb return spring backetry, and so on. The production intakes will have a vacuum port on top of the #6 intake runner (as pictured above), rather than on the side as originally planned (top pic) due to machining issues. 

Please select the proper 2V or 4V adaptor when ordering, which is included in the price. The 4V-A adaptor is used to mount Holley and/or Autolite 4V square bore carbs. The  2V-A adaptor is used to mount Holley and/or Autolite 2V carbs, while the 2V-W adaptor (not shown) is used to mount Weber 2V carbs. All of our adaptors can be rotated to any position (90,180, or 270 degrees), allowing the carb to be installed parallel or perpendicular to the crankshaft. You can also purchase additional adaptors (sold separately), just in case your not sure which carb you want to use. A GM 2V-TBI adaptor will be available shortly.
