You build an engine with .025" quench you'll be RE-building it sooner than you think. You've exposed yourself as someone who has never practiced what you preach with the Somender Singh groove bullshit. I've actually done it and it killed performance like you wouldn't believe. Why? Crevice Volume. It kills power and efficiency, which Vizard acknowledges. Distilled water? Most guys use windshield washer fluid. Can you point us to any of your builds as examples of your theories to provide proof of concept? J.Rob
