Stock ls6 max boost
Hey guys, so here's the thing, I have a stock c5z with a boosta pump, hotwire kit, 255 pump. It's on a 3.8 pulley now but I plan on doing a 3.4, headers, and meth. I race it a lot. Will this last?

yes until #7 r # 5 goes out on you. No good way to tell how long it will hold together. As you know it is only as strong as it's weakest part, which will be the stock pistons. Good luck with her man but it should hold for some time.

Everything is based on logging and monitoring.
Even the tune.
And, even stock PCM monitors plenty of things - such as knock - and will adjust real-time accordingly. But it won't help much.
Tuning is of course crucial and it is based on logging and monitoring.
Your engine reliability is based on physical components you'll use (and their suitability), used gasoline and as mentioned, the tune.
Not forgetting the intended usage.
5 seconds at WOT is very different than 30 seconds at WOT at standing mile.
Not all "safe" tunes are identical.

The meth should help keep temps down just make sure there's a failsafe if the meth stops spraying.
I'm not pushing my stock ls6 too much. I'd rather have it as a working spare and get a built motor for high boost. I can always go back and rebuild it with forged parts later if the built motor gives up the ghost. If you launch a rod through it trying to find the limit of the stock block it's worthless.

Turboguist ( I believe thats how you spell it) has full stock block and stock internals with meth injection and twin turbos, has around 800 hp I believe. From what I hear on the forums and from him, stock blocks can take a beating, just make sure you have a good tune and properly installed parts.

I'm just about to tear apart a customer's car I built back in 2004. Stock LS1 bottom end with ported 243 heads, small cam 220 ish duration 500 ish lift, vortech s trim blower car made 606 rwhp at 13 lbs of boost. Flash forward almost 13 years later and over 180,000 kms (110k miles) of daily driving all year round and racing at the track running low 11's the car has finally started consuming excessive oil. That said it still drove to my shop perfectly and doesn't show any signs of damage to any of the components. I plan to tear it apart next week and see what the internals look like. Hopefully we can just refresh the engine and put the car back together so my customer can enjoy another 13 years of driving and racing. So to answer your question I would say a stock bottom end can easily last a long life at your power levels.
