I guess will have to agree to disagree Don. A lot smarter people than me have tested indexing and it's affect on power using a dyno to measure the change.
I was referring to your post that indexing won't show on a dyno, that's simply not true.
Then we agree to disagree. However, I do agree that I made a very general statement and I should have qualified it by limiting it to the HD motor and my own testing. Every motor we tested had been modified and perhaps the dyno would have shown something on a Stage I or stock motor; don't know but seriously doubt it. I find there are many other little things that are often overlooked that, if addressed, will actually register on a dyno and/or reduce 1/4 mile times. Spark plug timing may be on that list but at the bottom. JMHO.:s
