Not to sound harsh, but a 250 six is probably the most reliable simple to work on engine you are likely to encounter. The tall deck motors have some quirks that make certain parts hard to get and the stock heads are horrible from a performance standpoint. not to mention that big block parts were 2-3 times as expensive as small even when they were currently made motors. I am not saying it is a bad choice......just saying that it is counter to your stated goals.
