Agree. (4.27 BTW). And technically it probably can't do everything the 2.7 can, but it can easily exceed any speed limit on any road on any grade in mountainous western Colorado where I live.my BB has the 2.3L with a 4.3 Diff. ? ( the one above the 3.73 ) and it is a well match drive train put together. 2.3 is able enough to do whatever the 2.7 can do for 2k $ less .
