Ken what is going on is I need more P/V clearance so I had to do it. My crank man gave me a (gram) # & I filled the notches with clay then dropped one of em into a burette & noted the CC rise then that # times 2.7 to get grams & as he said I am way under the limit but someone just mentioned that overbalancing is better than under so this is more of a curiosity question than an actual dilemma, that if I lighten a balanced assy (like I did) am I over or under balanceing...
