The story on the cause of the failure is with the crank and rod bearings on the journals that did NOT spin. It does sound like it's a
oil problem though. Hard to call it over the internet. It "could" be a clearance problem that caused either low
oil pressure or bearing slap (or both) but you would have heard something rattling or knocking before it cut loose while you was driving it those 1000 miles I think. Low
oil pressure could be from a lifter/block mismatch too. Clevors need the blocks drilled to cool em on the street. Was that done? I can ask a thousand questions,,,,,,,,,,,As for running a stroker, I've yet to talk to anyone (that means ZERO) in my 59 years that regrets running a stroker once they get them sorted. Can't say the same thing about the various other hot rod stuff out there.
