I wonder if a dollar bill 
is still made of EXACTLY the same stuff it was back then?
I know coins 
aren't.  I don't know about bills.
 
Personally, I'd kinda 
want something a bit more "verifyable", y'know?  Ok, hey, I'm sure the 
trick worked.  I don't doubt it.  But I'd hate to have to track down a 
"series 1963" note to be certain of it, is all.

  If you have the pan off, tear a corner off of a dollar bill about the 
  size of your thumbnail and remove the main bearing cap and put the corner of 
  the bill between the main bearing and crankshaft and torque the cap to the 
  correct pounds and see if the engine will turn by hand. do not use starter, if 
  it turns then the mains are not correct. If it does not turn by hand then the 
  mains should correct. I learned this from true old school real mechanic.
