I think there was a paper in Mathematics of Computation a couple of years
back with largish values of L. Don't know whether they beat yours but
they seem to have put quite a bit of (computer) time into it & looked at
numbers well beyond 4375 so I'd be surprised if they didn't find anything

Sorry to be so vague.
