Look what I found! well, I found out what was wrong with my car.
(previous thread: https://ls1tech.com/forums/generation-iii-internal-engine/190046-what-could-wrong.html)
It turns out that I had two broken valve springs
(Crane duals).
the inside spring was broken on each one. They only had @ 10k miles on them.
I put a pic on my webshots page under "broken springs" if you care to see them.

That's weird. I don't recall anyone breaking these things.

Great that you found the answer. I noticed in the other thread you removed valve covers and did a visual. I have dual springs ( ISKY-295D ) on my TR224, but of course without removing the locks etc. you don't know it's broke ( inner spring ). I've got 11K on mine, perhaps I should check ( I feel a loss of power compared to when it was new ).

Are the inner springs designed to be the "fuseable link"?

I guess that's the way they designed them?

In other words how did you finally figure it out?

I finally figured it out because I was changing out the vavle springs to the Patriot gold's because I had heard they had more seat pressure than the Crane's and I had already had some valve float on the dyno @6300rpm's with the Crane's. So I didn't find out they were broken until I pulled the locks out of them and removed them. Hopefully the Patriots will work well with the new cam that's going in also
