Call me superstitious but I think one of the design features of the old chain may have been lost unless you can find a real old chain.

Ever look at any new setup? It always has a rub bar to take up the slack and stop the chain vibrating back and forth. These old V8s don't have that but what they did have on the original chain was a chain that can't flex backwards. If you buy an old chain it comes in a "tank tread" format because the chain can't be bent back on itself by design. All the new chains (new bicycle type and OEM "silent drive" type) bend freely in either direction. Undoubtedly this lets them ship in a smaller box and stack more on a shelf. However, I think this is part of why the newer chains slacken up so quickly. They are free to vibrate back and forth in use in a way that neither the original design (with the original type chain) nor the newer engine designs (with the rub bars) allow...
