Noise...on revving while engine is at temperature?

[Powerhouse]

Hello all,

 

My engine has a noise upon accelIaration(usually under load) and also at revving. When the engine is cold it isn't there, or at least I can't hear it. It is a sort of clacking sound.  I have ruled out the clutch by pressing it in while revving and listening then as well.  I am going to do a few test this weekend to see what I can find out.  My engine has a sort of diesel like sound at idle..i am not sure if it supposed to sound like that.  I don't have any others nearby to compare it to anymore.  Maybe I am just gong crazy.

 

My rebuilt engine is a 218 mostly stock guts...just milled head .050

 

I am running a pertronix after not being able to get correct curve from that Langdon HEI thing.  I have a feeling the rod bearing or pins may be worn from accesive advance called for by the HEI.  I sure hope that isn't the case.  I just rebuilt this frikn thing under 2 years ago and have hardly put enough miles on it to warrant any premature wear.  I am not in the dough either so hopefully this will not brake the bank. 

 

Can anyone can give a listen and comment to the follwing video link.
