Compression test results - opinions
Did a test just to see how things were doing when I changed plugs out - it is an 11.5 to 1 LS motor with a good size cam 243/259 at .050. All cylinders were similar with an initial start of 130-150 then second turn going to 170 or so with a 3 one in the 190 or so with a 200 or so max after the 4th turn or so. Just wanted to see what others may have done in the past and results. Seems OK to me.

Don't worry about the max number(unless really low), Different camshaft profiles/ring gaps/types will result in different numbers. What you're really wanting to see is all numbers being within around 10% of each other.
