Ok, first I am going to rebuild my 400 since it just took a crap on me. I am in no hurry because I have got another engine in there and it will work until I get this one where I want it. I want to go slow and do it right. What is meant by a three angle valve job? What valve sizes for low and midrange power? Favorite cams anyone? I am not planning on going the high compression route because I want to run on 87 pump gas. Favorite phoenix area machine shops? I was told around 170 bucks for boreing and honeing my block, and 107 for grinding my crank. Dose that sound right? Favorite parts place? I am going to need pistons/gaskets/timing set/cam shaft/berrings/rings.
