Hello all, i'm not sure if im posting this in the right place, so direct me if i need directing. My next project, i am planning on putting the body of a 67'-72' long box chevy on about a 2000-2005 chassis. I am hoping to find either a 8.1 liter with manual or allison i guess, possibly a duramax to use. Does anyone have any information on this, I guess i've never even heard of it being done before. I dont even really know how to search for something like this. Any help would be greatly appreciated
