Recently acquired a 35 humpback with a nova subframe. Natural inclinations are to jump at the first GM small block donor car that looks good for drive train. I am wondering however, what others would be fairly compatible, such as a mopar 440, or 5.0 ford. If anyone has done such a project, I am wondering about clearance problems etc. you might know of. I have done a couple swaps, stuffed a 413 into a 41 master deluxe coupe few years back, so I can probably handle this unless there are serious compatibility problems with the subframe clearance. Any input would be appreciated.
