It shouldn't be too hard. There are some companies out there that offer motor mounts for such a project. I'm not sure if they do it or not, but try
http://www.dssracing.com . I know that they offer 385 series engines. But that's all I know. Also, the v-8 crossmember should work for the swap. I'm not 100 percent on that, but it seems like that's what I remember reading in MM&FF. Oh well, I hope that this helps some.
