She was a worn out pup. 150K on an unrebuilt 110 with AC. I bought the car from John and ended up putting the motor in a different car. One head had a burned guide on #5 exhaust, IIRC. I put another head on it and it was OK as long as you kept it under 65. Above 65, it drank oil pretty quickly. I put 13K more on it in a year before I sold the car. As far as I know, it's still going. I didn't have any more vapor lock issues after the head swap.

 The late John Moody -- famous for
 dissecting and analyzing Corvair fuel
 pumps -- had a major problem with what he thought was vapor
 lock on his
 last Corvair.  This was long before the addition of
 ethanol to gasoline.
 John tried all sorts of things, including carrying an air
 pump and fitting
 to pressurize his gas tank, to cure the problem.  I
 know he did a lot of
 diagnostic work on the fuel pump itself, including leak
 checking the
 internal valves.
 I always suspected it was some other problem such as leaking
 fuel line or
 clogged filter, but he insisted otherwise.  To the best
 of my knowledge, he
 never did solve the problem.  (No, he never did try an
 electric fuel pump.)
