906 or 452 which is best overall

I hesitated when asking this question. It seems whenever an opinion is wanted it turns into a war of words.As far as experience goes I have been building engines since the late 60's, both import and domestics. With that said, even I don't know 1/2 of what I would like to know and there is room for improvement for all of us. Remember opinions are like buttholes... everyone has one! And no opinion is wrong they only differ from others.

My apologies. Mine was not the intention to start a war. I just answered the question and the horse hockey flew. Again, my apologies.
