limitations of internals was wondering what exactly is the cause of stock internals to fail. ive seen some stock motors pushed and seem some fail. I know a tune is the biggest key but how far can you push a stock internal motor bfore something fails?
is the pressure to much for the rods?
is the pressure to much for the pistons?
just curious as to how far a motor can be pushed before it needs forged

Seriously, doing a search has saved me so many questions like this. There are probably 20 threads on this subject out there, some are very informative.
People have seen from 450-600 rwhp on stock blocks, its all in the tune/supporting mods.

Factory internals-
Pistons: wouldnt puch much more that 550rwhp
Rods: 500rwhp (550rwhp w/ bolts)
Crank: i would throw 1000hp at it all day! NO JOKE there are people on here that are in the 9s in the 1/4 with the cactory crank, maybe 8s yet?

550 you say? see thats what i was wondering. I seen some 4.8s making 505 on a safe tune. i think KBracing a site sponsor is seeing those numbers in his. i also think parish pushed little over 600 rwhp in his old 4.8. just curious as to if used meth and good fuel how far can a motor be pushed and how long

Our factory LS1 motors were not designed to do make/hold more than factory power.
Its kinda like a '10-bolt' question "i am throwing X amount of power at it, when will it break"
We dont know and we wont know until it happens, its just all a gamble.

Good tune + well maintained = a long time.

if you have enough turbo i like to go safe on timing and just keep adding boost till i am happy(or see knock). i like 15deg. i have never tried less but it wouldn't suprize me if more power could be made at 10deg but with more boost(tuning to the edge of knock)

550+ here... and I do beat it when I drive it. We'll see how it holds at the track real soon. Stock internals with 6.0L heads..... fuel mods/meth... when I drive it on the street I like to shift early, like 6K.
