360 la timing gear marks.
I put in a new cam and put the marks at 6 o'clock on the cam and 12 o'clock on the crank. I go to fire it up and the starter just spins really fast. I crank the motor over by hand and its very easy to spin, as if the spark plugs are out. So i'm not building compression. I'm wondering if I adjusted my rockers to tight causing the valves to hang open as I figured it would still fire if it was out of time??????
