Probably not in the right section but need a question answered by a Holley rep. Weiand made a tunnel ram 2x4 intake for the 409 Chevy decades ago. Did the mold survive? Does Holley recognize that there is a huge desire by 348 and 409 engine owners for the Weiand intake? I would guess 200 to 300 would sell quickly. Maybe that is not enough for an initial run or not. There are so many street rods/roadsters etc. using the W-motors that the Weiand tunnel ram would be snatched up for that market. Not to mention the serious 409 racers out there. And, the number is far higher than most would think. If I have posted this question in the wrong section, I apologize, maybe someone could suggest a section that a Holley rep. might see it. Thanks.
