Hi Ron,
Offset bores are a very common alteration to motors.
I cannot give you details as I am still involved with some engine folk and they would not look kindly on free information.
But, think of the offsets and the burn timing of the mixture in low rpm engines. (less than 10K) and you will understand the possibilities of offset bores.
You must think of overall timing events and the effective moment arms.
That is all I can say due to Non-Disclosure agreements.
