My 83 60 wagon just blew the engine after 495,000 miles. I guess it doesn't owe me anything. Now I have heard a couple hundred options of what to put into it. Something with a power upgrade and more efficiency- yet mates well with my 4 sp tranny. It's my everything truck daily driver, fishing, hunting, work, family plus my wife and daughter do drive it from time to time. Any experiences of what works and what doesn't. And where's a good place to get/order engines from.
