I thought I really DID read somewhere that either the 240 or NA 300 motor was in fact the world's most reliable engine. I saved the article but cannot find it now. Toyota 22R was the second. I wondered at the time why they didn't mention a "SBC" small block Chevy, or a Dodge slant 6. I'd really like to see some "true" data. I just finished reading a book, "SuperFreakanomics", that turned on it's head, many "beliefs" people hold dear. I'd like to see a good analyisis of data, that truly determines"the world's most reliable automotive power plant", for real, with no conditions, i.e., "we beat the crap out of this thing and it lived for xxx miles".Any powerplant that is cared for properly can go many miles, but I'd like to know, what engine lives the longest, period, statisically. I'm sure the data is out there somewhere.
