I'm on the hunt for a van, 4x4, AWD, 2WD, doesn't much matter. Gas mileage is a concern, but the real test is reliability.
Seems like there are tons of gas E150's floating around, and Astro/Safari are fairly common as well. I've heard vastly different opinions of reliability between the 4.3L Vortec and the 302/351 Ford. Some guys lead me to believe that most Ford gas engines are junk and that even the little 4.3l V6 Vortec is the most reliable thing since the Cummins 12v.
So, what are the most reliable gas engines out there?
