Sorry, I goofed. It ran 0-60 in 8.0 and ran the quarter in 15.8@ 90mph. That trap speed is high for that time, don't you think? Here is the link for all the stats. http://motortrend.com/roadtests/seda...jo/index6.html

Oh ya, since were talking about the STS i'll post specs on that too. That new Northstar can move but needs another gear to keep up with the BMW 545. It has a six speed auto. http://motortrend.com/roadtests/luxu...ts/index7.html

Shawn'* right -it'* like comparing apples to oranges.
That 3.6 would benefit ALOT more from a CAI than a L36, or even a L67. Even the exhaust and CAI will probably put that puppy well into L67 territory torque-wise -HP probably close to 280. Some cams, headers, CAI, full 3" exhaust and that thing would no doubt put a Y2K+ SSEi with the same mods (and a 3.25" pulley) somewhere behind it in the 1/4 (not by much,) but the gain from those mods would be better due to the 3.6'* ability to flow more and more air through the motor (not just before and after) as compared to the L67.

Ok... So I guess what I was trying to say is, best bang for your buck would be the L67 hands down.
Given enough money, any engine can be made better, but plain and simple fact is that the L67 due to it'* "old design" has MUCH more available and is a proven (over and over again) winner. Because it comes with a power adder doesn't make it a bad engine. I'm sure that if GM ends up using their new VVT engines for as long as the 3.8L has been around that there will be plenty of aftermarket for them, but I highly doubt that any automaker will ever again have a single engine last as long. Every other automaker has a different engine for just about every body style they have. GM has been one of the only ones that hasn't majorly revamped their engine lineup along with their body styles. The constant changes in engines makes it very hard for any aftermarket to ever appear outside of completely custom parts or regrinds of OEM parts, all of which costs $$$.
I guess I'm just a diehard push rod guy at heart. I had a 24v 3.5L in my old intrepid and I wasn't as impressed with it as I am of my L67. I'm really not all that impressed with my parents '97 STS compared to my SSEi. I even like the sound of the L67 over the N*. You can tell the difference between a push rod engine and SOHC/DOHC engine and I prefer the push rod.
There is no refuting the fact that a DOHC 4valve per cylinder engine should be more efficient. Throw in VVT and it should make for a very lively engine. I'm just saying that it'* not my cup of tea.

The Cadillac STS might be just the thing to beat up the 300C. Maybe even the CTS-V XLVi or what ever those initials are. We are just focused on th eBonneville to do everthing I guess when GM DO have other cars in the class to mop that 300C. AM I right or wrong?

L67 > all v6 engines ( well except the GN turbo 3.8 )[/quote]
What about the Syclone/Typhoon 4.3?
Also, GM has the motors to keep up with the Hemi......they just don't use them where they should. The LS2 is only slightly larger than the Hemi (6.0L vs.5.7) but has much more power (400HP vs. 345) and is no where near being fully developed (next-gen Z06 being the example). With the 5.3 being in the new GP GXP, they could easily put the 6.0L version in (the motors are the same size externally) which makes 345/380 in its best form, which matches the Hemi in HP, and bests it in torque by 10.
