Came across this list which is very useful for identifying what car your red motor came from.

Thanks Craig.
I found it a while ago via a link to a link to a link etc and found it very usefull for identifying which engine originally came from what car.
As always, I didn't write down the web address and couldn't remember it again, nor could I remember how I found it so thanks again for putting it up here.
Terry.
