So, I'm getting a clearance of .0012-.0014 on my 3' mains with the 113M speed-pro 3/4 groove bearings. I bought a new crank from Molnar which measures 2.9998 and thought that I could swap it out. So, I decided to measure the main bores without shells and I'm coming up with 3.1858. I know that the general rage is 3.1880-3.1890. So, does anyone know if this could be the culprit of these real tight numbers? if I got the bores honed to 3.1885, will it be enough to get back into range to say .003-.0036? From what I remember for every .001 of bore increase (with no bearings) you should see around a .0006 increase in bearing to crank clearance? Is this at all close to, right? Not sure if I should have the block line honed again.

If anyone could shed some light on this for me, I would really appreciate it,

Thanks
