What some of you guys don't realize or think about is that on a public forum like this We have anyone from a young child wanting to learn to the experienced engine builder. Some of our guys that post often and answer lots of questions are sometimes just "parts buyers" that buy from others and have engine builders that put things together for them. Not everyone should be taking a grinder to their blocks, cranks, rods, and heads as they could do LOTS of unrepairable damage. I've seen a lot over the years and like I said above I've been there done that on my 572 Keith Black build and there was no way in heck was I going to grind when I had so much on the line.
