    Either one will work.
    Out of curiosity, what class are you running? And why so particular about crank casting #'s?

    Most dirt track sanctions have the rule that crank must match block,likely goes back to the early 80's when the 377,383,388 became more affordable

    And if you don't believe it, Google Smokey Yunick!

    From Wikipedia

    Another Yunick improvisation was getting around the regulations specifying a maximum size for the fuel tank, by using 11-foot (3 meter) coils of 2-inch (5-centimeter) diameter tubing for the fuel line to add about 5 gallons (19 liters) to the car's fuel capacity. Once, NASCAR officials came up with a list of nine items for Yunick to fix before the car would be allowed on the track. The suspicious NASCAR officials had removed the tank for inspection. Yunick started the car with no gas tank and said "Better make it ten,"[4] and drove it back to the pits. He used a basketball in the fuel tank which could be inflated when the car's fuel capacity was checked and deflated for the race.

    Your joking right..I have a set of 6-1/8" Elgin rods you can't tell aren't "stock" left over from the look in plug somewhere in my stash.
     
  12. Creative interpretation and exploitation of the grey areas in the rule book... read between the lines. And it is not cheating unless you get caught.

  13. It would not be the first engine with 1 oddball rod or piston in it.
