None of the factory rebuilt engines had main bearings that were oversized on the OD. They did have recut thrusts. My '66 FB engine went together fine with a standard crank, and standard case. So did my '64 Ghia engine. And I bet they will last a lot longer than 20K miles. They will probably outlast me. -- Russ Wolfe '71 FB AT '66 FB MT '64 T34 (not running) '65 T1 (not running) '05 KIA Sorento SUV russw@classicvw.org http://www.classicvw.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
