i agree, but i don't have a cherry picker so that would be more spending needed. with christmas around the corner my choices are be cheap or wait a month to get started.

yes i found several videos with a similar sound that had lifter issues. also reading discussions on ls1 about comp xer profiles makes me wonder too in combination with the springs i found the motor is running on.

this is moving so slow with early dark and this crap weather.
ok, i have the pan off now. i found a little metal on the magnet but nothing to speak of in the pan. i was about ready to start pulling the head off today if rain doesn't chase me off, but was wondering if i should pull rod caps off first to check further on my bottom end?
with my frozen hands i couldn't find anything that stood out to me. i only get a little back and forth play along the crank, and no vertical movement. none on the small end/pin either.

Just lost a lifter myself after my Patriot Performance Stage III heads bit the dust and I dropped on a set of AFRs. Had about 150 miles on it and it crapped out. Chewed up a lobe on the cam & scraped up the bearings something fierce. Had to pull the longblock and get 'er refreshed. Got it done last night so I'm on my 500 baby drive. If its a lifter, you would have some metal in the pan - best to pull the heads and see what's going on before it gets worse. Most of all -DON'T run the motor again until you figure out what it is.

i have found a squishy(??) lifter, but nothing else. i can press the plunger down easily with my finger. the roller looks to be in great shape so i think my cam will be fine. i still need to pull the drivers side head off to get those lifters out and check them all.
if this is the cause of the issue i guess i can chalk it up as a failed lifter check ball? sure was noisey though for not being completely collapsed.

now that i could get out there with better-ish weather. i found a new problem. this is the rear piston on passenger side (number 8?). but this looks like old damage to me since it has carbon build up and my valve shows now sign of impact.
here it is out of cylinder
