Old Race 340 Teardown
I would think this engine would be pretty valuable to the right person. You could sell this for quite a chunk and us the proceeds to build a proper street ripper. Replicating an engine like you have would be super expensive. Not to mention the development and tuning that would have gone into it. It's probably nicely sorted out as a race engine. You may find out the expensive way why that intake is so cut up. I bet you spend way more making that a street engine than you imagine.
