49 commodore main bearings

Has anyone rebuilt the main bearings on a splasher 8 by boring out the area and fitting them with bearing inserts?
It was suggested by a machinist but don't know if it's possible.

    I have heard, over the years, that some people have tried to install bearing inserts from Jeeps.  The feedback that I got, was that the conversions were not successful.  I think it had something to do with side-to-side play.  With any luck someone (who's actually attempted this) will jump in here with all the technical information.

    Don't do it.  The mains are  stepped in size form front to back, and are soft white metal.   Modern shells are much harder and will wear the crankshaft. For Jon's info, the Jeep conversion is for  rod bearings only, and will only work  successfully on the '38 onwards design of connecting rod.
