The "infamous Australian intake" you're referring to is, I presume, the system from Morrison. I spoke w/them and have seen their intakes at various trade-shows over the years. And from what I recall, their intake used shorter runners.
So maybe this is the "Borla/Kaase" intake. Lance Nist would know for sure. Reachable via www.panteraefi.com
I recall seeing at least one Pantera with the Morrison intake. Looks like a great way to potentially fit everything under the standard engine cover.
I tried to buy a Morrison intake years ago but discovered they are made-to-order. The lead time is at least 1 year. Maybe things are different now.
I think the Borla/Kaase manifold could be made to work but it would likely require modifications or specific cylinder heads.
Keep in mind, a “stack” intake can be made to fit below the deck lid by the careful selection of components.
