cheers for the replies as i thought, not expecting alot from an old motor but just wanted to check if they had any massive problems with age being alloy and all. I dont have any engine re-building experince so would rather pay more and get a good motor to start with. A latter model lexus v8 would be better but the rover would be more than enough for my application and is a much cheaper alternative.
I read on wickipedia that rover manual trans were prone to breakages? that maybe the earlier 3500 models tho i think. do the water galleries corrode massivly? other than that they seem to be a fairly robust engine.
will have a look out on tme for the toyota adaptor sets. i think most people just run them with factory autos in conversions it seems..
