318/360 van engine roller valve train & AOD ?? year

[rustytoolss]

May be able to get a V8 from a late 80's dodge van ( I have not looked at it yet/ unsure if it's a 150 or 250 series)
What year did the dodge vans get complete roller valve train ? Also what year did they get A500/A518 overdrive transmissions ?

Roller 360 engines were 88-92
