MBHD, not, they are correct
The v8 small journal engines (265-283 early 327) and the 6cyl rod bearing for the 194-250 series ARE the same dimension. All bearing manufactures
list the same replacement bearing for both. We have been using the Clevite CB743HD in our aluminum rod engines for many years with great success. Yes you could easily drill a stock bearing to use with an aluminum rod, but there are, for racing engines, reasons to at least look at bearings that are directly made to use in that environment
