Use your stickies at the top of each forum page. Stock internals can hold somewhere near 500 rwhp if I remember correctly-your problem will be the transmission if you have an M6-its easy to break with stock power let alone anything additional.

I read an article in GMHTP, a year ago or so I think, that there was someone running around 800hp on the stock short block. I believe the car was a black Camaro. As for the rest of the drive train and engine, I can't remember. I just thought to myself, "That's something I wouldn't try".

I ran 576rwhp/590rwtq on the stock bottom-end for 3 years until I pushed a head-gasket. When the engine was torn down, it still looked new. I've read about guys (Harlan comes to mind) who've hit 700+rwhp on the factory shortblock.

From all the threads I have read on this topic I have come to the following conclusions:
300-400 rwhp is relatively safe on just about everything. M6's might have a problem with the 10 bolt rearend (if sticky tires are used) and autos might start having issues with the 4L60E (if a lot of drag racing is done).
400-500 rwhp is relatively safe for the motor but is dangerous for the stock 4L60E transmission in the autos and the stock clutch in the manuals.
500-600 rwhp is hit or miss on the motor, deadly for the 4L60E, deadly for the stock M6 clutch and in drag racing applications will also be dangerous to 10 bolts and stock suspensions.
600+ rwhp is basically a ticking time bomb for everything. You'd want to upgrade the shortblock, transmission, suspension, fuel pump, oil pump, driveshaft (if aluminum), rearend, ect.
All the above is only accurate when safe tunes are present. Running too rich or too lean can cause a variety of bad things to happen at any power level. My advice to anyone who does not want (or can not afford) to spend a small fortune is to keep the goal under 500 rwhp. 400-450 rwhp can be done without breaking the bank too badly.

You are right about Harlan using forged slugs...I forgot about that. The stock hypers are pretty tough for what they are, but won't suffer detonation lightly...especially the ringlands.
