Compression Question 300K mile engine

The Mantra here at FTE is "get the truck operating at 100% before adding power, chips, etc"

I'm looking at injectors and tunes but had a couple of things I wanted to do before pulling the trigger.

Did a compression check today and all cylinders were from 350 to 380. Is that what you guys would expect from a 300k engine?

If you guys say say those numbers are ok the last thing will be an oil analysis. I know, I know, Should have already been doing this but just haven't gotten around to it.

Thanks,

For a three hundred thousand mile engine, yes, those are respectable numbers.
