408 8.5:1 Compression test. What readings should b expected?
Going to do it this weekend and just wondering what numbers I should be seeing. I understand that it needs to be done at operating temps and that it aside from max compression, it matters how fast it gets there.
If I'm missing anything, feel free...

Thanks..
I got 160-162 w/ #8 showing 158. Thats somewhat lower than yours but I'm wondering if maybe cam and bore/stroke varies it some.
My cam is a..
Cam Motion 236/232 dur. @.50" .588/.574 114LSA 110ICL
Any thoughts on the numbers I got?
Oh, and your setup looks great!

Thanks! (our cams are close to the same)
Thats just fine for compression. yea cam etc does make a difference but you just want a ballpark to tell you difference between cylinders. Also the temperature etc makes a difference.
Go buy a leakdown tester, that will tell more about your motors health than just compression.

I'm seeing a little more blow-by at idle and generally more overall compared to when first installed.
