I talked to Smitty Smith, Technical sales Coordinator for Edelbrock, Saturday at Drag Expo in St. Charles IL. He says they are interested in producing a Performer type head in aluminum for the 348-409, but they are not sure of the interest and if they could sell enough. I told him that right now a lot of truck 348-409 engines are being resurected and they all need head manifold combos. I emailed him this morning and mentioned to him to think about a waterpump at a reasonable price to check out the interest there is. I asked him if he needed more input and if so I would post his email on-line. If anybody out there has some points to make, let me know as I will be in touch with him in the future.
