I installed a power package from edelbrock on my 289 small block. I am running with kieth black domed pistons. The heads are the performer heads with ford racing roller rockers, edelbrock hydrollic cam and lifters. I have adjusted the rockers and everything sounds fine except for one cylinder. The #4 cylinder has a tick to it and when I adjust the valve it gets worse. It doesnt matter if i tighten or loosen the sound either gets into a knock ( we all know that means I have tightened to tight) or it gives you the too loose clap. I am lost. I have tried to adjust the valve 30 times or more and it still makes the noise. None of the other rockers/valves make the noise. Do you have any idea what could be casuing this? Short of pulling the heads, I have ran a compression test and all cylinders are at 155 to 158. So they are all matching within the 10% range. PLEASE HELP.

On eof the parts is faulty - rocker arm, lifter or push rod. Swap the easy parts to another cylinder and see if the noise moves.

I thought the same exact thing while reading this. Good advise, try it and see. If you have done this 30 times, one more time to solve the problem isn't too much to ask.

I got it... It was the timing .. I had it set at 14 degrees advanced and the cam specs show 32 degrees. I did that and the car runs like a champ now. thanks

Are you referring to the ignition timing? Cam timing and ignition timing are two separate things. I have yet to see a cam card that gives you ignition timing. You probably had a lifter with a stuck plunger. Ignition timing won't cause or fix a ticking noise.

dude your over my head

That is probably why I had the issue in the first. This is my first car I have ever built. I am trying to do everything on my own. Motor and all. I am getting fairly lucky so. Anyways I dont know the differance between cam timing and ignition timing. i didnt know there were two seperate timings.

I know you set the timing with the vacuum advance off and plugged and then plug it back in. that is about the kist of my knowledge. If you would like to share your knowledge I am all ears. Thanks
