[Healeys] Specified Octane

[Greg Lemon]

Road and Track test specified premium in their contemporary road test, but 
didn't give a number, they used a RON octane number back then, which gave 
higher octane reading, now they use an average of RON and MON, which gives a 
lower number, I think Premium was about 100-104 RON back then, but somebody 
correct me if I am out of the ballpark.

According to this article http://www.osbornauto.com/racing/dragster.htm 
todays gas of 92 octane would be about 96-97 octane RON, I know it varies 
throughout the country, 91 or 92 is the best you can get around where I 
live, but if you could get 94 octane modern gas think you would be in the 
ballpark of factory requirements.
