top end tick on stock motor Hey guys, I have a 2000 z28. stock motor. Recently, today, I noticed a tick above idle on the passengers side bank. I am very sure it is from the valve train. What are the possibilities that a rocker backed off?
The motor has 27k on it. Its always had a slight tick. but more noticable today. Motor is smooth at any rpm`s. I run 91 octane, usually shell. I did put about 5g of chevrone in it a few days ago. Any helpm would be very appreciated.

Check to see that all plug wires are on good and tight. I had one that backed off the plug and was causing a ticking sound. Make sure they are all tight in the coil packs too. You could also have a bad wire.
I just re-read your post. If it only occurs above idle, it's probably not the wires. It would occur all the time.

Well I took the valve train apart the other night. I couldnt beleave how easy it realy was. I have 6 pushrods on the passenger side that have rub marks from where they at one point in time made contact with the head 
So I decided to go ahead and do a full on cam swap. I have the car all ready, short of pulling the timing cover, to do the swap. I cant beleave how EASY it was to take things apart. Im having a local shop, Force Fed Performance, custom grind me a cam. The extent of the mods for this year will be, LS6intake, Cam, Kookslt, Custom Y with dual electric cut outs, a 100-125shot, 36lb inj, and all the basic bolt ons. They say NA I should be at around 420-430rwhp and sprayed add another 100-125hp.
