Engine Health,what do you think?

The way we used it was in the pits, just plugged one valve cover and hooked it to the other valve cover, it was the way Ted Flack & John Worley from Chrysler advised use to do. If engine was really bad the float in the meter would bounce when spinning it over on the starter. Difference on a 358 CID modified engine between 2 cfm and 6 cfm was about 60 hp this was engine that made 680 to 690 when everything was perfect. Most times on a 6cfm engine leak down would be in the 5% range with the old style Sun leak down tester. The meter was a Fisher Porter flow meter not some cheap deal like Hamburger use to sell.
