I posted this question on Ranger forum and wondered what the forum braintrust here thought. I am no mechanic so it may be a silly question.

If you were to re-build a 2.3l Lima and they bored the block (say .030) to get everything back to smooth and round, are the connecting rods in the re-build kit "de-stroked" or slightly shortened to compensate for the increased volume of air being compressed?

And....if they are....could you use the stock connecting rods along with all the other new parts to get any measurable increase in compression? Would it be to any advantage or, if there was any increase, would it be so slight that it really wouldn't matter?

Thanks
