Compression testing
 
Does anyone with experience know what the compression test numbers ideally should be at for a 350?
Thanks!

Depends on the compression ratio of your particular set up but usually around 150 - 175 psi. What's more important than the exact number is that all cylinders are within 5 - 10 percent of one another.
