I'm doing a PI swap on my 96 GT and the new heads are on and I am currently attempting to time it correctly. I place the chain with my timing mark on the timing mark of the crank sprocket and attempt to drape the chain over the cam sprocket and the timing marks do not line up at all. I take a socket wrench to move the cam in position so that the timing marks line up and when I get them to line up there is all this tension on the top half of the chain (driver side should have the majority of the tension on the bottom half) and if touched, the chain will hop off the links because of the camshaft's tension on the valves causing the timing to be off. Does anyone know why this is happening???? Please help me as I am very pressed on time! Thank you!
