pinto piston offset

If im looking at a pinto engine with the flywheel to my right which way should the piston offset be, near or farside as i look at the block?
 
And what happens if its wrong way round?

It should be offset to the thrust side of the block, the far side.

If backwards the pistons may be noisy when cold. Some people intentionally install the backwards to help the r/s ratio slightly. I reckon you would be hard pressed to quantify the difference on a street motor

Traditionally the piston piston is offset to one side of the piston this is done to prevent the piston "rocking" as it travels up and down the bore.

Traditional forged pistons have the pin centred. This was a large component of their cold piston slapping. Current piston and ring technology now enables forgings to run quieter, be lighter and be more stable in the bore.
