This is Boyd from the sales department. Here is a list of parts to assist you in the change over to carbureting.
Intake manifold---Edelbrock 7577. This is for the late model Magnum cylinder heads. I have included a link to the instruction sheet for this item.
The following parts are required for installation of the manifold.
Carburetor models 1407 (manual choke) and 1411 (electric choke) are what I would recommend for your vehicle.
A Mallory 4309 fuel pressure regulator will allow you to use the factory in tank EFI pump and reduce the fuel pressure to carburetor requirements. This will require additional fittings to connect to your existing feed and return lines. http://www.summitracing.com/parts/MAA-4309/
The following distributor package will allow interchange from the computer controlled distributor.
We offer several different styles of aftermarket instruments that can be used. This link is generic, but it will connect you to all of the gauges, brands, and styles I offer.
There will be a bit of wiring need to be done to compete this conversion. Unfortunately, I do not have a conversion harness or know of any other supplier that does.
If you have any other questions, please let me know.
