Answer
 Hello Shaun

 It seems you are doing a rebuild on this engine.  There is either a dimple or line marked on both the crankshaft and the cam. If you cant locate these then your best bet is to take it to a mechanic and have him set the timing the old way. Trying to explain the procedure is long and really I dont suggest a non-mechanic try it because you can damage the new connecting rod.  

 One more thing: If you purchased a new crankshaft and there is no timing marks on it, take it back and get another one. Only once before have I seen this happen but it does.
