I have a problem with my new acquisition, an original 72 350/200 with 80k.
At idle there is absolutely no noise but when driving I could hear a ticking that sounded somewhere between a lifter and an exhaust leak.
Started it awhile ago and as usual it was quiet even when reving up at holding at steady speed. However, after I ran it for awhile, I started to hear it but it is coming from the front of the engine. It has an original fan clutch which is tight and the water pump is tight as well. Then I got to thinking, could it be the timing chain. When reving, a couple of taps seemed louder then the regular ticking and it only occurs when you get up to say 2000 rpms.
Could it be slop in the chain when hot causing it to hit the cover? I couldn't get on the cover with my stethoscope
