Defiantly. You can time the car completely without any marks. So this is your last call then if you thing it's all out. Find tdc on cylinder 1 and leave (there is a little cut out on the crank pulley which might be in place and could be used in the future), now remove rocker cover and have a look at the cam shaft. You want the cams to be sitting like this / \ over cylinder one. With the belt off if you turn the cam it should fall into position (while you can see its correct go ahead and check the cam sprocket marks). Now just the dizzy to sort. Dizzy cap off and look where there marks are, the rotor arm should aim towards the 6 degree mark, if not with the belt removed just twist the rotor by arm till it lines up. Now try and get the belt on without moving anything. This is also the time to make your own distinct flywheel mark and do the dynamic timing with a timing gun.
