Anyone with knowledge on switching short block from 1989 into my 1991 and putting manifolds, power steering, fuel rail, etc on to the older block? If 1991 is a High Output and 1989 is not (this is my assumption) will the H.O. items work/fit the other? If I just use the older motor with all of it's attachments there seems to be wiring, fuel line and emission differences.

Thanks for any help
