Not a big demand. The most desirable are the 225 hyper pack 4 bbl which are almost extinct. Chrysler changed the 225 and it became less durable but still good in the 70's something like 75/76 and newer. The way you can tell is by sparkplugs. The peanut smaller plugs are the newer design and don't have the oil cylinder with O ring that goes inside the head where the plug screws in. These engines also have a much smaller rod bearing width. Both good but the older gen was bullet proof.
