tech question

Asked this a while back but it might have been too soon... So...

Does anyone know what the bore size and spacing on the 14 is yet? Really looking for an answer on this one for tech reasons.

Bore & Stroke 84.0 x 61.0 mm
If your talking about valve to piston spacing, its a few 1000ths of an inch, really fricken close was what I was told. You can probably go +3mm overstock safely, I'll let you know when I get the pistons custom made. Nobody has any pistons right now, so I might be the Guinea Pig.

From the service manual: Cylinder Inside Spec Diameter = 3.3068 to 3.3073 inches. Service Limit = 3.3110 inches. Don't know the spacing. Piston Spec Diameter = 3.3055 to 3.3061 inches.
