 I'm still curious to know if the builder knew the engine was going in a 
Tiger... and that the Tiger uses an electrical fuel pump.  In my first post 
I eluded to this. I mean if the builder thinks gas leaked in to the block at 
the mechanical fuel pump then he's caught right there.

 I think Allan needs to ask questions of the builder in a ordered way so as 
not to tip him off, but see the builders "logic" or lack of.  In situations 
like this people often say, "something smells fishy."  It this case 
something doesn't smell "gassy."

  Hello all,
  A crankcase full of gasoline seems odd. How does a carb of any type 
overflowing for any reason not produce hydrostatic lock in a cylinder with 
the quantity of fuel described? What path to the oil pan is open to gasoline 
through the carb? In a properly built system; there is no such path. I think 
gasoline in the oil is not the problem leading to cam bearing destruction.

  Allan,

  There are just too many red flags to pin the cam bearing damage on a crank 
case full of gasoline diluted oil. Is it a small possibility (?) - yes, but 
very, very small.
  As it has been pointed out the gas would have likely leaked out the 
carburetor and been noticeable on the ground.  If per chance fuel had 
actually leaked into the engine it likely would not have started either 
because it was hydro-locked or been ridiculously rich. In any of the cases 
the smell of gas would have been noticeable.

  If the cam bearing was noticeable bad, what was the condition of the other 
bearing and for that matter the cam itself? To find that out the engine had 
to be opened up.  If only the cam bearing is bad it seems to indicate 
improper installation. That being either the bearing was misaligned (though 
getting the cam in would have made that noticeable) OR more likely the oil 
hole was not aligned with the galley. I would press the matter before 
accepting it as "your" problem.
