how much abuse can a stock lt1 take? I was just wondering how much abuse can a bone stock say with 70-100k miles lt1 take? like how much drag racing with 6k rpms shifts, etc etc. What are the breaking points of these engines? i know the optisparks don't like high rpms from what I've heard?
I'm not implying i abuse my car but i just would like to know more info about it, and its limits and weak points.

abuse? it's just an intake...all it does if feed air to the heads and no coolant flows through it. the only "weak points" i can think of is the fact that it is stock. porting and polishing to increase airflow and to accommodate a 58mm throttle body will over come it's "weak point" of holding back hidden power....

It shifts at 5800 anyway for stock settings, so you wont abuse it much more. Secondly thats low miles considering you want to abuse it,lol. Lots of nitrous can be tossed at it safely and you can make it last for quite some time. 70k mile motor is a baby in my eyes

again, i think the only problems someone will have with an LT1/LT4 intake is the infamous oil leak and the lack of air flow. .. now i'm pushing just over 500/570 rear wheel on a stock manifold and have no issues....since your pretty much stock, i wouldn't worry about it to much...

I have around 165k on mine and I have been spraying on it for the last 3 years.
I bought it with only 66k 6 years ago, and these last 99,000 miles have been pretty rough, I ran it pretty hard and it still runs as good now as the day I picked her up.

The PCM not only manages the engine to keep it performing at it's peak but it also limits the damage from foot to floor burnouts, reciprocating saw exhaust mods and kids that think the engine can run on octane booster.
By adjusting timing, cutting off fuel and switching to open loop the stock PCM can allow the user to abuse the crap out of the car without catastrophic failures.
HOWEVER keep in mind these poor things are between 13 and 17 years old. If you are going to abuse your LT1 change your oil, replace bad sensors and keep it tuned up. Poor maintenance will kill your motor way faster then an occasional missed shift or many WFO blasts down the drag strip.

How about more than 530rwhp. Shifting 6500+ at the strip. 150 shot and big cam. Stock short block. Now I know I am on the ragged edge, and this is not a daily driver but the LT-1 are pretty strong. If your tune is good you can make good power. Ken

Where are you getting intake from? The OP never mentioned that word at all. HOWEVER keep in mind these poor things are between 13 and 17 years old. If you are going to abuse your LT1 change your oil, replace bad sensors and keep it tuned up. Poor maintenance will kill your motor way faster then an occasional missed shift or many WFO blasts down the drag strip.
