i just got my std 400/512 Source crank back from being balanced. the machinist said he only had to take 40grams off the crank to match my rods n pistons. how do you go with a crank thats 3000 grams less to start with?
Just depends on WHERE the weight is and where it isnt.. I normally turn down the counter weight a considerable amount so they spin quicker.. along with a sharper edge on the leading edge.. I've want to do the same edge on the trailing side to reduce windage
