I have been trying to get a little more power out of my old 92 jag 440 and I did a compression test on the motor. I never did this before. I ran it around some to warm it up. Then I shut if off and tested both cylinders one at a time. One pull for each cylinder. One had 75 and the other had 85. Then I redid the test. This time I pulled 3 times for each cylinder. Then they both read 100. Is this good?
