What engine do I have???

Hello list,

I've got an early 72 TR6 that I'm in the process of rebuilding.  I've taken 
the head off, but I haven't had the time to remove the block yet, I hope to 
get to that this week.  I'm try to get ahead of the game and order my parts 
ahead of time, but I'm confused about what crank I've got (long or short 
nose).  The number on my block is CC60580E.  Can anyone tell me which type I 
have based on the commision number?

Thanks much!
