I've got some 86.5mm pistons to fit in the block. As they are American they are sold as 3.406"
These are the only spec details I can find. I would assume the pistons are designed to fit a 3.406" bore size (85.5124mm) so that is the spec I should give the machine shop?
I suppose this could be double checked by the machine shop by measuring the piston and adding 0.0035" (0.08mm)?
Don't want to do this again so thought it sensible to check.
