[kc911s]

I have a 75 911 and have stumbled across a 74 or 75 (according to the owner) 2.7 thst has been sitting in a garage for 15 years or so. What would this engine be worth knowing no real history on it? It is complete and has the CIS on it. I am wanting to pick the engine up and rebuild it and have a back up incase my engine bites the dust. What would this enfine be worth on the open market in its current condition? $4k? $5k? I have scanned the for sale section looking to see what the ask is on these ensigns- just don't see many for sale. Thanks for any info.
