'64 Dart GT: 273 to 325 swap ?
The 325 shares the bellhousing bolt pattern with the small block.....BUT the dowel pins are in a different location. Pretty interesting swap idea. Can you post pics of the 325? We can tell real quick whether it's a Hemi or Poly. Either way, it would have a lotta cool points. Would be some work, no doubt, but you'd have something different.
