What kind of 318 La..?

Bought another car some weeks ago & it has engine & trans from a van, long dipsticks & such, it has a 2 barrel carb on iron manifold but used to have injection, that means it's a roller cam engine, right? I've been under & saw by the relief number that it's a 318 but how &/or where do I see the year?
