66 Dart GT HT Whatsitgonnabe?

And it's here!
The seller didn't pack it too well but it seems ok. Dirty and one of the carb stud threads is bad. But so is one on my LD4B so that evens it out. :)
They really are very close to identical. The plenum on the LD340 is considerably larger and the ports are swapped. I wonder why they decided to make that change. Does it make the runners slightly longer?
Can't really see any other significant differences. The bungs and ports are a little difference.
The plenum wall has been milled down I think. Can anyone tell me what effect this will have, whether it's good or bad?
I'll clean it up and look for cracks but I can't see why I wouldn't make the swap so I'll most likely be sending my intake later today.
