    Its probably pushrods, get some chromoly upgrades, those can handle well over 7k rpms. Also take a look at you valve springs for any cracking. When my ls1 overreved I cracked 3.

    7.4 is the correct length with stock rockers i believe. someone should confirm this as it has been 4 years since i pushrod shopped.

    Well that was on kyspeed under the ls1 section so I figured most likely they were right but I wanted to check on here....so chromoly is good just what brand are preferred should I get different rockers while I have the valve covers off?

    7.4 are what it is most common used. After market heads will require longer or shorter one most likely.

    Thanks,

    yea my vote is pushrods....when your checking the rods, just check the head over like the springs and whatnot just to make sure everything is ok.....change the pushrods no matter if there bent or not

    advantage is lighter valvetrain = less power loss and can spin more RPMs if the engine is built for that


    if there a no name brand dont put them on....IMHO on a DD car i would run the stock ones BUT thats just my .02

    If your stock, and you plan on staying stock for a while you may want to just find used pushrods. Hopefully some of the mechanics can chime in, but I heard if you upgrade to chromoly's and don't have upgraded heads or internal parts if you ding past the redline again the strength of the chromely can mess up more in the valvetrain than if just replace for stock. I could be wrong and i'm not 100% positive, but check into it

    either way you can mess up the head stock or upgraded pushrods when you hit those RPMs, the only thing you stopping is the bending of the rod...its the price you pay in this game
