Hiya Bruce,
    Is that what happened to my microwave???? but anyway.....The VE
doesn't have anything to do with spark timing.(I know I'm going to get
flamed on this one),,,,The quality of the quench and combustion chamber
design has to do with the timing.....in the theory world if we have a
faster burning fuel(less octane) we would theoretically produce max
horsepower if we were to fire after TDC,,,,considering flame speed and
combustion but all of us forget about stored load for which there is no
known formula for in rotating mass(that I know of,,,,maybe next
diy_efi?????)      When you push on a wall with 200lb's of force it
pushes back with the same amount and yet it did not
move,,,hmmmmmm,,,,but it is stored energy,,,,,same concept within an
engine,,,we are all concerned with achieving maximum cylinder pressure
at 15 ATDC,,,,nevermind I don't even want to get into this one,,,,,rod
length/stroke/rpm/torque gets way to crazy for me tonight.....sorry for
the babble........
