Got a question, I'm installing a new cam in my 440. Before I started to take the engine down I made sure the pistons were at DTC distributor was at number one and both number one valves were closed, was I on the compression stroke I'm not sure. When I took the timing chain cover off my top sprocket ( cam sprocket ) was at 12 o'clock and bottom crank sprocket was at 12 o'clock on the old cam. After installing the new cam If I rotate the top sprocket to 6 o'clock to line up to the mark on the bottom sprocket the vales will start to open but if I rotate it back up to 12 o'clock the valves are closed which is where I need to be in order to take a measurement at zero lash to get new push rods so where do I go from here? I'm stuck and really don't know do I put it back together the was it was top sprocket at 12 and bottom at 12 ? Any suggestions ?
