The SM420 will bolt to the bell housing on the 292, GM was still using the sm420 until 67 or so.

For motor mounts go to www.stoveboltengineco.com

The biggest hurdle will probably be radiator clearance, the 292 is longer (and narrower) than the 235. Most guys go with an electric fan and a bigger radiator.
