I think the bigger advantages to moving the engine forward is to clear the IC manifold on the HC supercharger which also makes the SRV module on the 6.4 intake fit, to clear the oil filter mount and to make the low mount AC compressor work on the later VCT motors. I haven't set a column in my car, but I expect to still end up cutting the tube back, even with the 1.75" forward location the Holley mounts give. So I think it is more than making the steering column fit.
