And if tires or a speedo shop cannot get it close enough there are some street rod type places that make a custom gear box that inserts in the drive cable to correct or fine tune the RPMs the speedo sees. As I recall the boxes are made primarily for those that mixed parts so a brand X speedo would work with a brand Y trans and brand Z rear end but the principle still holds.
