your susposed to true and weld the crank when you get the cylinders ported. if your jugs are stock, than its not nesecary.

Stock cranks have the pins pressed into the counter wieghts. To true them is just to check and make sure they are all lined up properly, and then to weld them is to weld the pins to the counter wieghts so they can't move. It adds extra strength if you are making big power. It will require removing the crank and having it done some where. Unless you are making lots of HP it's not needed. If you just have bolt ons don't worry about it, but it's good to get done if you split your cases for some reason.

i wouldnt worry about it even if you are ported. my brother ran his stock crank for a long time very hard with no problems. wait till it breaks then go stroker.
