ive notice the bore size on a standard au motor is 92x99mm and the XR6 is 93x99mm my el is an xr6 would this make a difference if im going to a au motor with a 92x99mm bore or should I get it bore out to the same specs as a xr bore size

Who says the bore is different between an AU block and an XR6 Block?

Bore is the same for the 4.0l since it began. Same for E series 4.0, AU 4.0 and Barra 4.0.

Where do you get your facts from?

If you engine has a 93mm bore, then it is 0.75mm oversize, which is approx 30 thou over.

Bore for E series 4.0 is listed as 92.25mm Nominal with a stroke of 99.31mm nominal. Std motor & XR are same bore.
Bore for AU is listed as the same as the E series, again no difference between Std, XR or VCT engines.

Well they are wrong, stroke and bore is the same, compression ratio is different, 9.3:1 for std, 9.35:1 for XR.
