after warming up the car today for 2 mins i went to the road and pushed it a bit into 6500 rpm
and after a while the i heard the engine knockin and it didnt stop and the sound goes up when ever i press on the rev, seems like the lifters r done and i void my warrenty with the 4:10 and the LT i dont think ill get it back to the dealer.
anyways i dont really know what happen until i open up the engine, and iam thinkin to stroke to buy a stronger engine components valve springs , intake valves , exhuast valves, and stroker kit.
i saw the SHM and i dont really know any other guys that do this engine stuff?

why dont you swap the LT's out and put the stock manifolds in. It sucks but it is worth a new engine. The dealer will never know if you have 4.10's. Also, Ive heard bad things about SHM. But dont jump to any conlcusions until you take the valve covers off and see what the valvetrain looks like.

 

i made alot of cutting and weldding in my stock exhuast, and they might know that i added a somthing btw dealers are over here are so crap about adding anything filter LT or what so ever.
anyways i might do that..
or i would open the valve cover and see whats going on over there..
