Never transplant a motor you haven't heard running, it might be knackered.
I know someone who made this mistake quite recently with a Toyota Celica and changing the engine in the final generation Celica is tad more time consuming and involved than in a Cortina....
I had suggested buying a crashed Celica and robbing the engine but it was apparently cheaper to buy an engine from some bloke down the pub whose mate's sister's boyfriend's cousin had one lying around the garage...
