I think you are getting the same noise I have. I thought it might have been a lifter since I'm running .644 lift on a 228 degree intake lobe and high spring pressure, but that checked out.. I thought it might have been a loose flywheel bolt that maybe didn't get Lock-tite when I had the new SPEC clutch put in.. but with the clutch in and idling, it doesn't change. The noise goes away when the rpm's go up with mine, so it's not bearing related, and likely not lifter related. Oil pressure is 60psi at cruise. I am 100% sure mine is an exhaust leak. I think the rear header bolt drivers side got stripped, and not to mention the collectors were slip-ons, that were attemted to be welded, but I'm betting a weld came loose with all the vibrating the engine does.
I've had the noise for almost 2 years now. I hear it in the same place, mostly under the car. I did notice the other day that there were some black marks coming from the passenger O2 bung on the Y pipe, so I really need to get that checked out if it's leaking there.

oh, and juiced, yes that does sound very similar to mine, if you rev it a little it almost makes more of a knock than a tick but at idle its more of a tick, and if i rev it a little while driving then let it coast in gear i cant hear it sometimes, like the sudden oil pressure build up makes it go away for a second, and jjd49 i dont think think its tranny/clutch related because it does it doesnt change the sound any with clutch movement or gear engagement, which i wish it did so i could just take it back to the tranny shop that did my rebuild and tell them to fix it lol

Hey guys, sorry it has been so long since ive updated. I was racking my brain and spending hours and hours trying to find that noise and finally figured it out after buying one of those mechanics stethescopes. The only place you can hear it internally with the stethescope is from the bellhousing, but not a sound from the oil pan or tranny, so im thinking flywheel or clutch related, so im taking it back to the tranny shop wednesday to let them look at it and fix it since it never did that once before i took it to them, but god am i releaved its not my engine and i found that damned noise!!!!!! ill keep you posted as to what they figure out

I had the same problem here years ago in a old fbody, would drive her around and after 15 minutes or so it would start ticking. Oddly enough I swapped out the Fram oil filter I was using and it was gone. I believe the Fram was starving the car of oil.

Never mind him that's just what he does.."No offense G". I'm fixing to go on a dead thread hunt and say what I have to say until the MOD squad closes them down or locks them up. That'll put an end to all of this real quick..LOL
