Pistons

Yes and you could of answered most of your questions with just a Google search, (like most of us do) and your asking a very particular question about an engine your don't have or seem to have any interest in and even if you did doesn't seem like you plan on doing a rebuild and you had answer in your question.

It don't overly seem like you want to learn, it just seem like you look for possible trivia questions to post, just for whatever reasons you have but learning doesn't seem like one of them.
I have done Google Search and sometimes I don't find what I'm looking for and I thought that asking the one's who have the experience was the best thing to do. For example, I asked why most on here have used KB pistons instead of using Speed Pro pistons. I entered that on the Google search bar and believe it or not For A bodies only came up. As far as having a interest, well of course I do if not why would I be asking questions. I did find out about the ring end gaps needed for both pistons ( believe it or not but I found that on my own ). KB pistons require the rings to be gapped according to what kb requires and the Speed Pro pistons can be ran with the ring gaps reccomended by the ring manufacturer. The KB pistons are more prone to the top of the piston breaking due to the top ring location, apparently the kb's are more sensitive to detonation than the Speed Pro pistons are. Now I'm sure that your wondering where / how I came across this information, I Google it, is it correct? I don't know. This is why I asked about the differences between the two pistons, it had nothing to do with having a interest in a particular engine or even rebuilding one, it's all about learning,learning from the one's who have the experience with these sort of things. Is Google helpful? Sure it is but it always doesn't have the answers that one maybe looking for and there's no replacement for one's experiences. Have a good day.
