It is too bad that you have a Jasper rebuild.

Take the rods to a machine shop and have them checked. But, don't be surprised if they tell you that the rods can't be sized to standard.. A common problem with Jasper rebuilds. They are built to Jasper specs. NOT OEM specifications.

Jasper uses almost every core they get. That means some rods are bored oversize in the rod journals big end which require an oversized OD and an undersized ID bearing. Not common to the aftermkt retailers. You have to be real careful and have good measuring tools. When building one of their products. They use some real odd ball stuff compared with what the average enthusiast is used to.

The same goes for main bearings and cam bearings. Very common to encounter +.020 oversized OD/.020 undersized ID.main bearings and .020 OS cam bearings.
