Nice to be able to cut through all the cr** you read on here with a post that has actual facts.

thank you!
i really love the 2v ohv architecture...i don't think much of 3v. it strikes me as odd that gm has developed one of the best v8 period...and nobody cares about the v6.
the epa has asked mfg to stop the hp wars...which opens the doors for torque - large ohv, and diesels. if honda couldn't make the great peak hp, their engines wouldn't be worth anything.
the 4.3 is based on a 20 yr old design. how can gm perpetuate a design that shares no parts or technology with any other engine, be it v6 or v8? either it will be updated, or replaced with the 3.9 (i give it until 2010). the top of the line ridgeline has a 3.5. mercedes just developed a 90° v6, so nvh isn't an issue with that architecture.
gm appears to be squeezing out the 4.8 too (no aluminum versions), or it's made the 5.3 aluminum to justify the small power difference, and separate them in cost. imho, they can rework the heads (ls3 style) and get 345+ hp/ 360 lb-ft from the 5.3.
as far as cars, i didn't see the 3.5 in the line up. it's being replaced by the 2.4. the 3800 stops production in the next month or so. the 3.9 lives on in the lucerne for now. again, it's strange that buick gets a dohc v8 when cadillac won't. afaik the ultra is cancelled.
