I used to know the formula that is used to equate todays octane in relation 
to the octane system used back in the early 70's...If I am correct 
...today's method would require 105 octane fuel to be equivilant to the 
minium 98 octane fuel back in 71'...anything less requires that the engine 
timing be detuned.  I am curious to hear how many people are running a P6b 
with our low octane of today and not detuning the engines...also if so ..why
