need a 318 timing cover

motors a 70 but not picky on year of cover..just wanna get one thats not cracked and will fit...also need a 4 barrel intake and carb if anyone has one..fig might as well do a few upgrades while i have engine tore apart, gonna swap the whole drive line for a 440 and 727 in the spring so dont wanna invest to much, but thinking about putting engine in a A body or somthing down the road if i keep, or if i sell the drive line having nicer parts on it will help sell it faster..
