Hey guys, I have a 68 chevelle with a 327, rebuilt about 2 years ago. Bored .040, L98 Heads, Hei Distributer(older one), Air gap intake, Comp Cam 1.5 rockers(Hyd not rollers). I just recently started to get the clacking sound. I adjusted the valves to no avail. I tried to troubleshoot and took each set of intake & exhaust rockers, rods, and lifters out individually. After each set, I restarted the car and it still clacks. It sounds like a normal valve clack...maybe a little lower in pitch, but it is loud enough to hear if I am outside the car. Any suggestions?
Thanks,
Daniel
