     Greetings all,
     FWIW, I have successfully removed this bolt on different cars more 
     than once by using a breaker bar (or a long bar on the end of a 
     ratchet), with the socket on the crank bolt, and positioning the crank 
     such that the end of the bar just is on the ground. Then use the 
     starter to rotate the engine for a moment, and voila! the bolt just 
     spins right off. Of course, you have to use common sense, of which 
     there does not appear to be much on this list, so I will itemize the 
     caveats:
     1. The direction of engine rotation combined with the "handedness" of 
     the threads must be such that the bolt will be loosened, not 
     tightened.
     2. It helps if the ground is hard, like pavement or concrete, 
     otherwise your assembly will have to be dug out of the earth, and the 
     bolt will still be on the crank.
     3. Avoid having the car actually start. I have heard that LBCs can 
     occasionally fire right up, even without a ballast resistor!
     4. Using a torque wrench is tempting but the wrench may be damaged.
     
     I'd like to hear how you ultimately get it off, as this is on my list 
     in a while.

     Andy,
     I replaced the gasket on my TR6's Timing cover several years ago.  
     That extension bolt is right hand (normal) treaded so keep on tugging. 
     Mine was a real bear to get off also.  I forget the size but I had to 
     borrow a neighbor's box end wrench 'cause I don't have a set that goes 
     that large.  BTW the extension is held to the crankshaft pulley by two 
     (I believe) locating dowels.  So you'll have to give the extension a 
     couple of gentle taps after you finally get the big old bolt out.
     bye for now
