The 292 should fit...with some work. I seem to recall that there are
two different crankshaft bolt patterns used on these engines, one is the
normal later 6 and V8 design with 6 7/16" bolts and one dowel, the other
is similar to the 235 with 3 dowels and uses 1/2" bolts. Finding the
automatic tranny flexplate for the 3 dowel crankshaft may take some work.
Also, the side mount bosses on the 292 are offset, one is further
forward than the other, so a crossmember engine mount wouldn't work too
well, you'd probably need to use the type of brackets that bolt to the
frame rails.
I've never done this swap, so maybe others have more info?
