Ok people, help me out here I am starting to put my motor together and bought a dbl roller timing chain (melling) from a well known vendor and slid it on and there is a little bit of slack, from what I have read is that the chain will stretch even more once it is broken in, I don't want that, what other chains do you all recomend, I see one is the dynagear and the other is cloyes any others. help since I want to put this motor together by this weekend.
