Over-rev?
Over-rev? I am just starting to build my Camaro, but I was wondering a few things before I get to deep into it. I was told the major killer of LS1's, when they are NA at least is that they like to spin bearings, and that is mainly from revving them too high.
I was looking into a Texas Speed Heads/Cam combo, and was wondering if having a powerband to 6500 is too high for a stock bottom end LS1. I know a really common thing is to install the LS6 oil pump, which I probably would do when I installed the heads/cam, but is there anything else I should know? Thanks.

Not at all, my rev-limiter is set to 6800 and ive bumped the limiter numerous times on a stock bottom end motor no issues for 6 years+... 346s are no joke! 
The key is to beef up the upper powertrain like rods, springs, and lifters to handle your application. only worry about bottome end when go FI and your pushing over 600RWHP

No they don't snap. If they snapped you wouldn't spin bearings, you'd kick rods out of the side of the block. They can stretch, but they don't snap.
So when I go to replace the oil pump, put in stronger rod bolts? How do you guys go about doing this? Just pull on of the rod bolts, put the new/stronger one in, pull the other, put the new stronger one in? No messing with the bearings or anything?
What the goals for the car were probably going to be were the Texas Speed heads/cam,fast 90/90, possibly tsp headers, and maybe a 100 shot after that.

Katech rod bolts are a must in my opinion. My rev limiter is set at 7050 on my 402, and the shift points are set at 6500.

I completely disagree with the rod bolt debate (WHEN NON FI AND UNDER 600RWHP, UNDER 6500RPM)
it's simply unnecessary, and is a huge job to undertake.
keep her under 6500 and you'll be golden.
again, I don't think upgraded rod bolts are necessary- this is assuming you don't pull 7000rpm shifts all the time.

yes they do snap. I never said anything about spinning rod bearings. Bolts have snapped and sent parts flying. They stretch and they do snap...
With that said, if I put the new rod bolts in, what would be a 'safe RPM' to spin the motor to?
