stock bottom end limits I have been reading threads from a search over the past few days and keep getting sidetracked by cam threads, haha.
Here is my question, roughly what are the stock bottom end power limits? I understand there are variances in type of power, etc and that the 01-02 have tighter tolerances or something with some kind of beefier bolts on the rod ends or something?
Anywho what is the range of the stock bottem end limits?

I've heard the later gen 3 blocks have stronger internals as well. Anybody know for sure which are more reliable? I'm looking for 550 RWHP FI on my stock 2000 bottom end (ported ls6 oil pump, double row chain, comp lifters, comp PRs, top end ect...).

from the shops that i have talked to 500 rwhp is the highest and safest area to be around. The guys who have more than that are FI and there are always debates that FI destroys stock bottom ends. Every block is different and every driver has different habbits but i would go with the pros that work on these all day long. And they usually tell you 500 is your limit.

Well I am ending up having to replace the entire hydraulic system and am wanting to plan a clutch around the stock bottem end because I have no plans on touching that at all.

I have seen many a stock bottom end hold up with 600+ HP FI...
If the tune is right, and the driver is not overly abusive, there is no reason why it should not hold up for a long time.
500-RW can be done NA, very safely, and for a long time...

not doing boost, will be N/A and possibly spray every now and then. I know the N/A will be less than 500rwhp, but the spray would obviously put it over the top, thanks for all the suggestions guys
