well, what if you have a jacked up short turn that shows up at 28 but not at 36? does that mean that the short turn is ok now because your pulling so hard on the port that it doesn't show up?

I know Smokey went thru this when he decided that 28 should be the number. How many inches is the piston pulling once its past halfway down the bore?

If it shows up at 28 as a SMALL issue it may or may not get any worse but if it does get worse in my testing the issue needs addressed. I can only go to about 34 inches on my bench. Lots of discussions on this but it still comes down to the fact that a valve is at .500 twice and .700 once, that is if you have a 750 lift cam by time lash and pushrods deflection is factored in.
