Re: 66 289 Engine
The majority of classics sold had I6 motors, but if you pick up the guide, it only has info on the V8 motors. You have to go out and buy the I6 manual seperate. For a DD, the rebuilt motor will be better as it holds a lower chance of anything breaking on you. The "upgraded" suspension is also good, but depending all upon what you mean by upgraded. For a DD, I would also reccommend that you at least convert the front to disc brakes (if they haven't been already) and if you have the time, extra money and really want to be safe, convert the rear to disc too. If you need more info on the disc swap, lemme know and I'll give you a link to my friends site.
