Ticking Noise please help!
Hey guys.. I installed a new cam, heads, injectors, U/D pulley & Ported TB. I've always heard a ticking noise so I changed the springs and lifters but still have that same ticking noise and it seems to be getting worse. Anybody have an idea what this could be? Thanks guys.

How old are your plug wires ? One thing to try is to start the car in a dark garage or at night, lift up the hood and look for anything arcing.
I've also heard that an injector can make a tick or snapping noise when its clogged.

The valve train is noisier with the larger duration higher lift cams.
How did you determine push rod length? Going to a cam with more lift means you probably have a smaller base circle and need a longer push rod. You can't be certain unless you check a few of them to see what your lifter preload is. Too much preload or not enough preload = valve train is more noisy.
It all depends on the heads, gaskets, and cam you mated together. Ya gotta check it.

Hey guys thanks for the replies.. I used a pushrod lenght checker to determine the length of the pushrod I needed. I'm running a Torquer III cam with a lift of .647"/.598". The only thing that I still have stock is the Roller Rockers which I'm lookingto buy here very shortly. The motor only has about 400 miles on it and runs very strong except the damn ticking noise. All the plugs and wires are new so I'm kinda ruling thoses out at the time but I'll keep ya posted on any findings. Thanks Again..

Is it a ticking or a chattering? As in does it seem to happen once per engine revolution (or ever other revolution) or is it much faster than that? If the latter, then you may just be hearing the classing "sewing machine" sound of a built up top end. If the prior, then I'd start by looking real closely at those rockers as you say they're the only original parts left and they are a common failure point. Make sure you don't have any puked out rocker bearings.

If you don't already have one. They are a lifesaver when it comes to tracking down noises. You just put it on, then poke that probe all over the valve covers with the engine idling. If one of them is awry you'll know REAL quick.

Make sure your pushrods are at the correct length and that you have tightend everything down correctly.
After that, what some users on LS1tech found, is that a bad seating of the oil ring on the pump will make the valvetrain tick from the drivers side #7 cylinder. Maybe a long shot but I'm sure that was a PIA diagnosing that problem.
