My buddy'* parents' '05 STS has the 3.6.

It may not be the 3800, but don't go and write it off just yet.

Heck, we're just scratching the surface of their power potential, as evidenced by the new 1/4 records set recently.
i'd like to see the 3.8 in the soltice

Where is this OHC 3500 - 3900 info from?

These are still pushrod engines...

The 3500 is good for 200 HP and the 3900 is good for 240 HP...

The 3900 can also be had in the SV6 with the sport package... This will be the last year for the pontiac Van.. iirc the SV6 is not even in production any more...

And I'll state it again,

The 3800 is a Buick designed V6 with 90* seperation between the cylinder banks...

the 2.8,3.1, 3100, 3400, 3500 and 3900 are all Chevy 60* V6'*

The 3800 was great, but it'* time has come. A 90 degree V6 is unbalanced, and can't be as smooth as a 60 degree, it'* also a complete iron block/head engine. This makes it MUCH heavier then a similar sized aluminum engine. In the block alone of an LS1 vs the matching Gen 3 truck block the aluminum LS1 is 88 lbs lighter. The 3900 is also designed to rev better, and be more compact physically.

FAR from it. New hemi'* The LSx engines, The 3.5, 3.6 and 3.9L V6 from GM are all pushrods and competitive in their category. GM has sucessfully integrated variable valve timing over a bigger range then Honda'* Vtec.

I'd say keep the Northstar and go RWD.
Northstar & RWD? What'* the point? An LS2 is significantly cheaper then a Northstar with 100 less HP. It'* significantly smaller and lighter, with displacement inside. It'* also more efficient with fuel. It'* redline is a little lower, and it'* not QUITE as smooth, but those are very small differences.

This is a good point for debate. You are 100% correct that a 90* six is typically the most unbalenced motor there is. But, with balence shafts they can be very smooth. The Series II is for some reason incredibly smooth. I don't know exactly why but it is. I've driven N*, short*, and the latest RWD Cobra motor. All are DOHC, all aluminum. And for some reason my S2 L67 seems equally as smooth.

Exhaust and how "hot" the motor is effects as well. As do motor mounts, etc.. The only way to make any power with the 3800 heads was to boost them. As long as the 90* family is improved upon it'll be even better then our 3.8s.

Someone else mentioned the 350 being around still after being killed off. The LSx series of engines are the 3rd and 4th gen of the ol' SBC...
