I am trying to buy a Austin Healey 100/4 engine that is complete and was removed from a running car about 3 years ago. It is a long block but has some ancillaries like a set of carbs and the intake manifold and the distributor. What should be a reasonable value I should pay for this engine ?. I know it needs a rebuild but the chances are it might run in its present condition without a rebuild. I am sure someone would suggest I check the bearings and rings and clean it up before installing it if I were to go the latter route. can someone give me an idea what a complete 100 engine would be worth ? Thanks in advance for all your replies.
