Default LM7 redline?

I'm swapping an '02 LM7 into my '88 300zx. I'm trying to modify my stock gauge cluster, but I don't know what to mark as my rev limit.

My dad's 2001 suburban has an LM7 it shifts at 6000 so I would bet this is a good starting point.

If you run a stock cam it runs out of steam around 5K rpm. It will certainly rev higher... just fall on its face for power. If you upgrade the cam the limit will be the rod bolts. With upgraded cam/springs and stock bolts 6500rpm should be very safe. Upgraded rod bolts and supporting cam for that powerband then 7K should work.

I have ARP bolts and will be upgrading my cam and springs for at least a Z06 cam. Haven't decided if I have room for the turbo or not, so cam choice may change.
