I had a 65 Coronet convertible that was just itching to have a Hemi in it. I had a 392 I got in a trade for some big block heads. So I ended up getting it rebuilt. Before the swap could take place, the convert went bye bye. Someone on this forum has shoehorned a 354 in an early A Body; I think the 392 is wider taller deck) than the 354 and would be too wide to fit in my 65 Dart wagon. Oh well.
