Read that entire link to get an idea of how things work. Then read this: a stock lt1 pump has preload on it from the factory. Installing a lash cap will only move the piston up higher in the stroke. It will not increase the stroke.

I agree and I started a thread over there a few weeks ago asking about how the cap increases pump output with no additional stroke. I was told its where the cap moves the strokes operating range. It relocates the operating range to a more optimal zone. I of course asked if anybody has solid data to back this up and there is none. So its still speculation in my book.

Heres the short thread I started
