Ok guys a little help! I have a .60 over 350 with all the good stuff I could buy for her. I had the motor built about five years ago and it now has about 20,000 miles on it. When I first put the engine in my camaro I noticed that the lifters were kinda loud but never paid much attn to it cause you just could barley hear it and the motor ran so well. But i have just finished putting the motor in my 87 ext cab s10 and the lifter noise is driving me up the wall. I took my heads #416 to the machine shop and had them worked. I had them port and polished, gave them a 3 angle valve job and upgraded the springs. In the truck I can hear the motor much better (not sure why) which is why the lifters are driving me insane. I have adjusted them untill I cant do it anymore. What I mean is I can adjust them and there fine but just as soon as I put a few thousand rpms on them they start making noise again.
Let me explain. At an idle no noise, WOT no noise, Its while your just cruising that there tapping away. I have read and read all I can and everyone just says check to see if the studs are pulling out. There not pulling out and as a matter of fact they have not moved. Can you guys help me with this?

How about this? Perhaps this could be part of the problem. Tell me what you think.

My block is dated 67-77. As most of you know when these motors were placed in cars the timing tab was in the center of the cover.(right?) Well you can not buy this timing tabs anymore and must use the aftermarket which mount on the side. Well when it comes to the balancer that is a problem. If I go and buy a new balancer for my block the timing mark on the balancer will not match up with an aftermarket timing tab. As a matter of fact at TDC the mark on the balancer is striaght up. How do I time the motor right? What am I missing? I feel the motor is timed right but cant figure total timing like this? What do I do?
