Great info again there Adam thanks! Well I'm 99.9% certain the woodruff key was put back in mate (can't be 100% if I didn't do it myself), but they are reputable engine builders and built my friends GT and my uncles vr6 a few months ago & theyre running fine! but I think ill give them a phone in the morning for my own peace of mind. But to be honest i think ill be replacing the pulley at this stage for a new one anyway since I've came this far.
