I was thinking of using the Hemi from the Revellogram '71 Cuda in mine, because I have an extra one. If you are using the twin scoop hood, maybe the ducting from the AMT '70 Super Bee under the hood? A 440 six pack air cleaner from the '70 GTX would be close and could be modified to work on the kit 440. Hart's parts also make a stock RT hood that has that little dome in the center for the current 1/24 Super Bee, so you could use the 4bbl intake from the recently reissued '71 GTX. You would need to find an air cleaner, I am sure there is something out there that would work.(Revell '68/69 Charger or Dart?). Of course, if you are looking for super detailing, the older 1/24 Monogram/Revell muscle cars will need some upgrading, whether that's part swapping or scratch building. I think they look pretty good when they are built and they really do go together nicely.
