Interesting - you mean offset across the engine, not in line with the
crank? I've never heard of such a thing. Not saying you're wrong, just
that I've never heard of it. I did hear of one engine (Cadillac maybe?)
where at some point in mid-production they reversed the pistons as this
made them quieter. But I have a feeling that this was a split-skirt
piston. Frankly I'd be surprised if a fifty or sixty thou offset mould
make much difference to anything, but that's just my opinion of course.
Most pistons in my encounter have an arrow or similar denotng which way
round they should be fitted.
How would you even notice such a small offset I wonder?
