LQ9 Bore ??
Have whatever block you use sonic tested.
Honestly boring to the max is a complete waist of a good block. YOu should run the least amount of bore that you can. That way if you engine dies, you can still bore it and rebuild.
THe difference between standard bore and max bore is probably less than 5-10hp

It has been done before but with the water jackets filled all the way to the top of the deck (no coolant) and on a race only engine. Mine is 4.07" and is half filled (up to the water pump ports). IF your block can take a 4.06" or 4.07" bore that is as far as I'd go IF you are willing to half fill it.
