Going to Build 470 Street/Strip Engine for 71 Demon

I was looking for 270s but i quess there are not many options for intakes for lowdeck with Max wedge port size? I know, Indy makes singleplanes but is there any tunnel rams? I assume that custom cam would be great choice specially with tunnel ram?

Drivetrain will be 727 transmission with reverse manual valvebody etc. + Dana 60 rear.
That's where your hot-rodding skills will be tested or made, making things work that aren't supposed to. The tunnel ram I have is just a wieand standard port, I welded the outside of the runners and ported it to a larger gasket size.
I'm now getting ready to do it again to a larger size port. The 270 port is still relatively small compared to a real max wedge.
