74 Challenger with twins

Finish welding more of the cold side. More grinding than welding though.
Compromises everywhere. Wanted a smoother sweep into the TB, but intake tube is already close to header. Plan on welding tabs to it for mounting yet another heat insulated shield.
Top portion of tubes show are full welded. Left bottom open to allow for puddling the inside also.
Bottom cap will be lapped and can remain "ugly" and not seen.
Completing this portion was not in my immediate plans. Change of plans because as I am learning and dialing in the tune, I figured no need to "learn" twice.

Being a bit burned out on cold half welding, I moved sideways to fun stuff.
Finally fired up 3D printer and made these air intake ducts.
Currently only PLA for cheap testing and refinement.
But... is it cool.
Next up will be interface adapter cone that tucks behind headlight ring and holds everything in place.
Inside area surrounding filters will be boxed in with aluminum.

Modeled and printed the headlight cone.
Looks terrible in black.
Will try grey or silver similar to grill.
May add a bit more curves to tapered face.
