Chrysler use-to have a real good engine back then called the 225 slant six they say it could run & run for tons of miles, however It did have a flaw in that sometimes the #5 cylinder rod would crash thru the block. They also say Fords 300 Straight six is a good engine, but I had one of those and I had alot of trouble with mine on a old 1981 pick-up truck, everything from vacuum leaks at the intake gasket to worn cam shaft lobes and low cylinger compression and oil leaks.
The 300 was a good engine, but by 1981 it was so choked with emissions equipment it barely put out enough power to move its own weight. That was likely where the vacuum leaks came from. My dad had an 83 F100 that had many of the same problems. He ended up plugging off a bunch of stuff and it ran a lot better. The "good" 300s were built in the 60s and early to mid 70s.
