High RPM Noise
At About 6,000 RPM and higher I get a "clicking" noise from what sounds like the driver's side front engine bay. Any ideas what could be causing it? Is this a typical lifter noise? Any help is appreciated. Thanks Again.

Seriously though, how much mileage is on that engine, and how frequent do you find yourself @ 6000+RPM lol? Are you still running the stock valvetrain...?

Still stock, except the hypertech III which allows the RPMs. Only rev it that high after a few " too many ", but it is still a problem. (LOL) Should I just tune it down to around 5500, or really be concerned? (37000 Miles)

yeah change those pushrods. I dont have a cam or anything and i changed mine. Worse thing u can do is over rev ur stock valvetrain and bend ur pushrods. Changing them aint that hard also. I did em myself
