Thanks Gordy. Mine is much shorter. Maybe due to mine being k321? I hope so anyway.
A while back there was mention that the 12 Hp and 14 Hp are the same block, just the bore is bigger on the 14. And that you could have a 12 bored out to 14 Hp, then a few things to do for balancing. So it should be the same dipstick.
Something for you to check. I measured the outside of the block from the bottom at the motor mount up to the flat the dipstick seats on, and got 9-1/2".
