Much of the hoopla surrounding the V8 diesel DuraMax hyping up its arrival was "best in class" this and "best in class" that and "best in class" everthing else.
Yesterday I picked up the Jan 2001 StreetTrucks* magazine and came across an article introducing GM's new lineup of midsize SUVs taking the place of the current Blazer and Jimmy. Quoting from the article it says "The new 4200<cc> is an all-aluminum dual overhead cam straight six that provides the power of a V8 with the fuel efficiency of a six-cylinder. . . . In a effort to create a 'best in class' engine that would dominate the V8 engines of the midsize SUV class, engineers tested 24 engines at wide open throttle for 150,000 miles. . . " While it does appear this will be an impressive engine, it amuses me how GM can get it right with a gasser but not a diesel

Data on Vortec 4200
Bore/Stroke 3. 66" x 4. 01"
Displacement 256cid
Compression Ratio 10:1
HP 270 @ 6000rpm
Tq 275 @ 3600rpm
Valvetrain: Twin cam, 4-valves per cyl
If this engine lives up to expectation it will generate more than 1hp per cubic inch, which isn't bad. And typical of sixes, the bore is smaller than the stroke. Despite the hoopla GM likes to generate about its new products, it is very refreshing for American auto maker to see the light and go back to a basic tried-and-true engine design.

*I am not a subscriber to this magazine, which features slammed street trucks almost exclusively. I thought it would come in handy in finding accessories vendors for items like wheels, hoods, shifter knobs, junk like that. So don't worry, I'm not planning on adding any 5" drop kits or hydraulics or any such thing to my Ram
