318 heavy duty

I just got a 1984 dodge diplomat cop car for parts.It has a 318 4 barrel engine in it.It is a 318 heavy duty with fac engine oil cooler.Do not know much about this kind of engine so maybe some one on fabo can help me.
Thanks Jim

I think the old cop car motors come factory with double roller timing chain, and a windage tray. not 100% sure tho, i could be thinkin' of sumthin else....
