Olds stroker crank

Question for the experts:
can a Olds 455 N crank be turned into a 4.5" stroker crank if it has already been undersized .010?
also does any bbc 7.1 rod work for this?
Thanks

Yes, you’ll still have enough there to do it. And yes any BBC rod will work but it’ll need to be narrowed on the big end in order to fit on the journal with enough side clearance.
