but i didn't take the other spark plugs out and I did not hold the throtle open...
I just wanted to see what it was...
oh but my motor has 11.3-1 CR

A stock b-body LT1 usually tests around 200psi and f-body would be slightly higher.
My stock shortblock with the heads and cam the compression is pushed to 11.5:1 at 100K it cranks nearly 230psi.

I tested my 165k block a few weeks ago. I was lazy and didnt know how long it would take to do it, so I removed only 4 plugs at a time. I think removing all of them just helps not to drain the battery.
Anyways, I tested average between 200 and 208 on all 8 cyls.
