Negetive! This part is the only simple part. An FE block bearing is an FE block bearing they all use the same mains/rods does not matter what crank
I also recommend asking some questions in the FE engine forum of FTE.
Keep in mind there are a couple ways for an FE to become a 428. a 390 can be bored out enough to be a 428. There is also the 'true' 428 with the larger stroke crank 3.98", where the 390 crank has a stroke of 3.7..." there is also a 427(pretty much the same just was called so to differentiate i believe) also, but i cannot remember which one is made what way?
But none of this really matters unless your after a replacement crank. Sounds like all you might be doing is pulling the crank, having it polished and ordering the correct undersized bearings. i would expect to have to either use std size bearings(if it hasn't already been touched) and deal with lower oil pressure because of a larger clearance(while still might be in the spec. range) or have to get .010 undersized to compensate for turning of the crank.

Casting and other marks--beware, no guarantee this is 100% correct:

427 is an FE motor. Same bell pattern as the 428. NOTHING shared with the dead dog 351m/400, Nothing shared with the 385 series 460/429.

Bearings are the same, but you need to check the crank to see if it is turned, worn, or within stock spec.

If your not sure what your doing on the lower end let your machine shop supply and assemble it. When I did my 428CJ the machine shop wanted $200 to assemble the lower end and thus warranty it. Cheap insurance in my opinion.
