A while back I bought two prototype engines that were never installed or ran. One is a 2.2L TIII; the other is a 2.2L Masi 16v. Both have unique prototype valve covers as well.
I haven't done anything with them and they are still on the shipping pallet. They both have some pre-production oddities but could probably be cleaned up/installed/ran. The TIII would be easy, but the Masi would take a little more work thanks to the really weird timing belt tooth shape the sprockets use.
Would I be crazy to install these and make a running car out of them, or are they best left alone as they are? I'm sure I will just keep them but sometimes I wonder if some things are too rare to be used. Thoughts?
