cylinder compression

[mcaguitars]

I'm selling my truck and did a quick compression test. My truck runs great, but I was surprised to find, what I felt, was the compression on the low side (125-130 lbs). Has anyone done a compression test recently...and what are the averages found?


Thanks,
Roy

A lot of factors will affect compression, (gauge, engine size, piston compression, cam, etc...) the key is if all the cylinders are close to the same with each other.
When I did my truck a few years ago the good cylinders were around 125 on my motor but I had 2 cylinders with burnt valves that were 90 and 45
