LBZ rods

How can you honestly say that? Tuning is the biggest factor in this equation... cylinder pressure is probably the biggest killer of rods.
personally, I think LBZ rods are underrated. To my knowledge no one has broken any (because all the LBZ/LMM's just crack pistons first, and then guys rebuild them with aftermarket rods) and very few people have bent them,
My own opinion is below 700rwhp you will be fine, depending on tuning. Tomac bent his (didnt break them though) after more than a season of pulling and drag racing, beating the crap out of them with a big turbo and dual cp3's... JMO tho.

My stock LBZ rods and pistons look fine. They have low miles on them but did see 740hp on the dyno and several low 12sec passes. Tuning and egt management have everything to do with that.
good read and alot of the info i was looking for , the only thing i can add is i think in the last few years tunning and such has probably streached those max safe power #"s a bit . motors seem to be taking a bit more these days than they used to at higher power.
very true but the problem is the extra on top of that minimum that is not needed to acheive X power level . how does drive pressure affect cylinder pressure and is it only on the exhaust stroke or power stroke as well ?
i have recently experience in real life that lower drive pressure actually can scrub boost from less pressure on the other side of the valve . has me thinking about a few things ( unrelated to this thread for the most part )
x2, i think there is also a difference in forced induction (turbo) drive psi. the two people that bent lbz rods had a a5000 turbo and dual fuelers which usually run at a 2:1 ratio drive psi wise. compared to a compound turbo setup (not huge ones) that usually run at a 1:1 or close to it, have lesser issues. like trent said, tuning plays a role in it too.
I believe they are a decent rod, better then the LLY/LB7. I believe they will live at a sane HP level, but tuning is a part of that.
I bought a set of aftermarket rods for my LBZ, if and when, I ever need them. Why? because if I take the time and cost and add it up, good aftermarket rods are inexpensive in my total cost of a conserative engine build.

Exactly. Your already in there so wtf why not? Piece of mind is worth quite a bit to me.
