    9? i take it your moded pretty good? i dunno another thing common is piston slap ... but i dunno how likely that is if you didnt hear it before....

    i remember i redlined my iroc z really haard and blew the manifold gaskit.. sounded like a ticking noise but it was the exhuast manifold...

    post a sound clip video and im sure others will chyme in

    Na, do you have basic mechanical skills? Remove coils, which on your car I think you have to do one by one. Then remove valve cover and then remove each rocker one by one and pull out the pushrod. Just roll it over a piece of glass and see if it's straight. It's probably on LS1howto.com

    I'll have to check with my mechanic but I believe we went with Comp Cams pushrods. They have a thicker wall??? I dont remember. It was 4 years ago...

    He also suggested I let the PCM do the shifting...

    So, you let the PCM shift for you. Wondered why, now I know! I'm sure the shift is set a bit higher than stock.

    To OP, check with KY speed, a sponser, for pushrods. Sure sounds like a classice push rod bend. Hope nothing else got hurt, if you really did rev it that high. Mayber somebody removed the rev limiter on your car....dumb thing to do unless your engine is built for it.
