67 Cuda 5.7 Hemi Tranny Advice Needed

It's more than just cutting the tunnel, 545RFE uses pulses for speedometer signal, no cable. However, the 545RFE having the .67 overdrive means you can run a very steep rear end gearing and still lope along at 2-2.5k RPMS at 70. Stock 2011 Ram hums along at almost exactly 2000 rpms with 3.91 gears. Gas isn't going to get any cheaper :sad5: There are some pictures floating around the forums of how much members had to cut out of their tunnels. Just adding more info to the pile :D
