<VV> Hardened, (or Nitrided) Crankshafts

[Cliff Tibbitts]

I have a 110 block with the original crankshaft and am running 140 heads on
it.  I don't have any concerns at all.  As some have mentioned, it might be
different if this was an all out race car or subject to a lot of stress.

Hello folks,
  Recently, I was having a phone conversation with "Big John" Kirkman  about

an engine I plan to build. It started as a 65, 110 engine with PG.  The
engine 
block has been assembled, using the stock 8409 crank. The cam has  been 
upgraded to Clark's OT-20. Plans are to run .040 pistons.
  Now for my predicament. I have a set of 65, 140 heads in the machine  shop

that will probably be ready this week. Although I still have a few  more
ducks 
to get in a row, I thought this would be another upgrade I could do.
Problem 
is, the crankshaft is not hardened. Remember, the engine is a 110.
  Since the crank uses the same part number, regardless if it is  hardened
or 
not, is there a visual inspection I can do to determine a Nitrided  from a 
non-Nitrided crank? If not, is it possible to get a crankshaft  hardened?
  At this time, the only other late heads I have are for a 95 HP  and I
don't 
want to use them. I'd get a set of 110 heads first.
  In case you're wondering, no, I don't have car to put it in  yet. That is
a 
bit further down the road. Right now, I just want to do the  engine.
  Any info that anyone can provide will be of great help.  THANKS!!!
