Did my motor just let go?

Don't tell me that! lol

Question: If it's not something easy and I have to replace the motor...Would labor cost be much different to swap in a Mark 8 (and retaining my intake cams/oil pan) vs. swapping in a Mark 8 and doing C-heads/intake?

Took me about an hour, I didn't find it hard.

Minor Update - Didn't drive the car for about 6 weeks....cranked it up this weekend to move it around the driveway...ticking began immediately...went inside to grab something, came back out a few minutes later...ticking was gone...drove it the next day and yesterday and still no ticking.

IDK what to think, but I'm going to bring it to a place locally that builds modular motors to try to finally address the power-loss issue, burnt oil smell at high rpm, and i'm guessing replace some parts to try and prevent the ticking from coming back. I'll update again once we figure it out.

Sounds like a lash adjuster, may just need to replace them if they are the original ones.

Yes, I'm hoping that is the case...will likely replace them all in addition to chasing the issue on why it feels down on power and getting more of a burnt oil smell after high rmps....I'm guessing a compression test and leak-down test is in the near future...I'd also like to dyno the car to see if it really is down on power.

Bad lash adjusters will decrease valve lift which in turn decreases duration and would effect performance. Not saying that is your problem.

Compression test will only reveal cranking compression which still will not tell give a true reading of the engines condition. A leak down test will reveal a lot more and will tell you if the engine is in good condition. If you haven't already done so pull the plugs and inspect them, check for the obvious things like fouling or oil, if they seem ok then stick them back in. When you pull the valve covers inspect the chains as best you can and inspect the tensioners, then pull all of the lash adjusters and check to see if they are functioning.
