I've got the shift points on my Lightning, with a supercharged 5.4L and just about the longest stroke on a production motor, at 5,800 rpm with no issues.

You'll run into valve float issues long before you 'blow up an angine'.

And there is no computer safety cutoff feature that does what is described...they'll have a built-in rev limiter but nothing that will cause an engine to break-up throughout the rev range to protect against spinning to a 'stratospheric' 6,000 rpm.

No problem spinning any of the LS-X engines to up near 7K on stock parts, the limiter on my Z06 is set at 6900 rpm. Now will the truck make power over 6K.... most likely not but that is due to tuning peramaters and camshaft profile.
