Once the ol lady gets back from visiting her family, I am going to take my truck to my friends shop and have the compression checked. It's been suffering from power problems, so aside from fixing the cracked exhaust manifold and checking over the ignition system, I was going to have him check my compression as a starting point.

Any of you have this data so I should know what to expect?

there's some links to get you started, but we need to know what year and what engine before we can really start to help you.

 

Oh, duh. Sorry.
