At 93 octane you can run up to 11:1 is what I have been told (assuming you are talking about a 400EX since it is in the 400EX section).

With +2 arms and 3:2 offset (stock) you should be close to 49"

With +3 arms and 3:2s, you would be over 50"

I hope that helps.......

It could be for any bore size, providing it's 11:1.
