Default V6 intake to 4BBL Carb

I must be missing it but I am looking for the article on how to convert the intake to a 4BBL. Which manifold do you use to convert it. Thanks for the help

You need to use the 66 and up Magnum manifold, several of us on this site have built them. Best thing is there is no welding necessary for this conversion, just milling, cutting, drilling and tapping. Don't know of any article but TJ had posted his procedures on his conversion

Thanks guys for the info, It looks fairly simple on the mill. I just need to find a magnum manifold. John
