What is a good redline on a stock block
Hey guys I am going to be putting my lt4 hotcam in my car in the next week or so. I had a question for the tune. What would you guys recommend for a red line. I was thinking around 6300. Would this be ok to run on a stock bottom end with 157k on it?

The problem isn't so much the block as it is the rod bolts' ability to keep bearings under control.
The further you push beyond 6200, the more risk you run.
I shifted at 6375 for most of the 2007 season without issue, many have gone longer.
Bearings looked fine when I pulled it apart to build the 383.
If you decide to play with fire and push it towards 6500+, I suggest you have a
"build my new motor" fund ready.

LT4's shifted at 6,300 from the factory and they are basically the same shortblock, but that was when new. As long as you have good oil pressure and don't leave at that rpm for long you should be fine.
