When you do that make sure your on the firing stroke not the exhaust stroke with the NO.1 cyilinder at TDC.I put a timing chain in but the guy who sold the car to me put it in 180% off.After we figured the stroke out it was a peice of cake.The (old timer) showed me by taking the plug out and put his finger over the hole to see if it sucked air or compressed it he also took the NO.1 side valve cover to doulble check .I hope I have that correct.If not some one will proof read it . good luck Dan
