Hugh Mongus Registered User Join Date: Jan 2014 Location: Tulsa, OK Posts: 360	Engine Compression I compression tested my engine tonight (dry). Six cylinders were 150, one cylinder was 130, and one cylinder was 160. What is a good number for compression in a 350? Should I be worried about the one cylinder that was low? I've always been told all cylinders within 15% is ok. Looking for any information. Thank you in advance.
