Default LT1 rev limiter

What type of rev limiter do LT1 engines have? Is it electronic like the LS1s? Is it safe to hit the rev limiter in an LT1 the way the LS6 guys like to do?

The ruby is chip controled. I am not familiar with how they (ls6's)do it? I hit mine a couple of times before the chip mod and it didn't hurt a thing. It just pops like a misfire and the rpms drop below the limit. I believe it was around 5,800 rpm. Once you re-flash your chip you can ride it up to 6,500 without to much of a problem. If you have a stock cam it quits pulling at the rev limit anyways.

It cuts out the spark, if your behind the car when it kicks in you'll see how rich the car goes. You can bump it, but I wouldn't with the stock bottom end.
