Red line on a 420

What is the red line on a mid eighties generation IV 420?

I think it was 5200

The cam is the same as my 525SC and my WOT operating range is 4800-5200. The rev limiter is just past 5300.
The 525SC and 420 have very similar specs and good internals. I would not be afraid to turn it 5400.
