correct, they are not fuel injected, they use two stromberg carbs, one per bank, as per reliability, they are a bit underpowered, the bottom end is not cross bolted (4.0 and 4.6 are cross bolted) and if the oil pump looses prime you need to pull it apart and fill with vaseline in order to prime... they leak just like any other rover and because they are multy belt drivers, rotating parts such as water pump and power steering are becoming a little hard to locate... the 3.5 is the only of the v8s to have a small cylinder bore all others have large bore cylinders shared among... the heads are shared among all rover v8s, the change is in the valve stem after 1990 to reduce accumulation of carbon.
the 3.5 had a metal head gasket which is later replaced by composite, there is a little work to be done with the job... bell housing pattern is shared among v8s, so technically you could take a later 4.6, 4.2,4.0 or 3.9 and drop it in place of a 3.5...a little work is in oder so a few things can be transfered from the 3.5 to the 4.6
