    I'm working on a 67 Belvedere that came with a ton of original GTX stuff. The hood is pretty much perfect and assumed it was GTX but the scoops are blocked off in front and there's no cut outs in the hood underneath. Were the originals functional?

      Has anyone ever try making functional? Possibly with an even older cross ram intake design? I'm not sure how well the carb centerlines line up? But eyeballing looks close?

      This cross ram intake did show promising results with increased air flow to the lower torque range RPMs. But because it was not ideal for upper RPM? (Nascar use) just adding carb complexity it was not further developed. Though not super speedway worthy? It would be a legit street/strip option? (There are decent articles out there explaining the advantages. It better deals with the back pressure that develops in all intakes. Thus actually recycling some of that loss to some gains.) (Small free boost?)

      Doug's GTX/Belvedere may be an ideal candidate to try? (Just thinking outloud?)

      That is a very interesting thought/idea. Later manifolds had shorter port divider walls for better higher rpm use. I've wanted to run one on a gasser wagon I have, very badly. The good manifolds are a little pricey for my blood, especially considering it would mostly be for show, even with the good set. Wish I had a set to mock up on the GTX, to see exactly how close they are to scoops, just for the hell of it.

      Yes. Looking into this a bit? There are a few Runner length and design options. I'm sure it would need some sort of snorkel or custom grabber type design. 2 mini grabbers? With similar water drainage?

      But you are right about the price on those intakes. Plus the cost of a nice 2 scooped '67 hood? Plenty of risk trying? My fabrication skills are not up at that level. But I'm not too bad with Autocad? I'm estimating the setup would be in the neighborhood of $10g after carbs/fab/hood/intake/parts ect... Not sure it would be $10g cool? And that price estimate doesn't include fixing or fab errors. It would have to have some proveable funtional benefits to get some attention? But certainly would be unique.

      Those 30" cross rams don't fit a B-body very well. Although the driver's side will clear things, the passenger side inner fender would need to be hacked up for plenum/carb clearance. The is due to engine offset in engine bay. That picture of the 30" ram components is very nice. Although one sees the intakes for sale, the matching exhaust manifolds are rarely seen.

      You're right. I didn't consider the offset. I'm sure that would just be the beginning of many design issues? Lol.
