stock bore is 84.5 which gives 2.8 L, so 3.2 L is more than a few extra ccs!But how thick are the cylinder walls of the other 4 cylinders?
Is it really worth that extra few ccs?
The 4 are serviceable and as Mark says, if I need a rebore later, they can have liners too. or I'll get the other block out of the shed
