I have an 82 Elky, with a carborated V6 engine. The carborator needs rebuilding and the engine needs a tune-up, but I was considering putting a 350 in that I have in my garage. The 350 is fuel injected, so I have been told that I would need to get new mounts, computerize my Elky, and get various other parts. Is this true? And if so, how hard would it be to put the 350 in, and how much would it be costing?
