Replying to: alpha01 (Jan 13, 2005 12:13 pm) You are correct with those two engine but you also make my point on few and far between. You only listed two that made decent power, but you don't state that there are motors, 4s, 6s & some 8s, that need to be revved into the high rpm-range to make the grunt, if they have decent torque at all. Again, there are far more OHC engines that need to be revved high to hit a their torque range than those that don't. Sorry but this is not a stereotype, it's fact. As stated in my post, I acknowledged there were DOHC & SOHC designs that made decent torque numbers at a usable RPM, even mentioned that some of these designs start making good numbers a little above idle, as well as in the mid-range, just as you pointed out. Assuming that you really read the post, wonder why you forgot to mention that point as well when you were trying to make yours ;}.   The response was to fraiserdog in that even though there are upsides to OHC layouts are there are downsides as well. And second, just because it's an OHC design, it doesn't make it automatically BETTER than OHV. Replies to this message: alpha01 (Jan 14, 2005 9:17 am) alpha01 (Jan 14, 2005 11:08 am)

Replying to: jae5 (Jan 14, 2005 5:35 am) Time prohibits me from naming every engine thats OHC or DOHC, I just used two that popped into my head. Note they are even went smaller displacements than the Chevy 3.5L.   Going with the same size displacement, the Nissan 3.5L and Toyota 3.5L also post impressive torque figures. Since the Nissan 3.5L is sold in the U.S. alone in over 500,000 cars and SUVs annually, thats not "few and far between". With regard to the Toyota, the peak of 260 is fairly high- at 4700 RPM, but the curve is said to be fairly even, so Id have a hard time thinking that that engine is not making the same 220 foot pounds at 3200 RPM as is the pushrod GM engine of the same displacement. And the DOHC engine won't be completely winded by 5000 RPM.   Since we're talking about examples, can you cite an OHC design that posts low torque for its size?   ~alpha Replies to this message: alpha01 (Jan 14, 2005 11:08 am)
#124 of 3460 3500-VVT by z9z9z9z9 Jan 14, 2005 (9:50 am)
Hey, anyone know the details on the 3500 VVT?   According to the Chicago press release this engine has a 99x76 mm bore x stroke, so it's NOT the same as the non-VVT engine in the Malibu, which is 94x84 mm. The 3900-VVT is a bored version (99x84 mm) of the Malibu 3500, and it seems like they "de-stroked" the 3900 for the 3500-VVT.   The Impala press releases suggests looking at the "powertrain" press release for more details - does anyone know where this is? Sorry if this has already been posted, but I don't have the fortitude to read through any more of those "OHV sucks" threads...

Quick, take a look at the ad banner on top of this page. That is a nice looking car. Why can't those boneheads from GM design something that looks great?!!

Replying to: alpha01 (Jan 14, 2005 9:17 am) OOPS, I included total Altima sales in my statement   "Since the Nissan 3.5L is sold in the U.S. alone in over 500,000 cars and SUVs annually, thats not "few and far between"."   Its over 300K, I believe.   Sorry!
#128 of 3460 Engines by frasierdog Jan 14, 2005 (9:49 pm)
I have driven the 3.6L in the LaCrosse and the 3.5L in the G6.   The 3.6L is quite and has a very smooth power band all the way to the top. This is a nice motor.   The 3.5L is not nearly as smooth and does not have as flat a power band.   I really wanted to see the Impala with the same engine as the LaCrosse.   Oh well, when the Impala hits the showroom, I will try the 3.9L and see if I like the whole package.
#129 of 3460 Impala LTZ, Big discounts on '05s by bh628 Jan 16, 2005 (6:10 pm)
Hi, I am a newbie, but I have heard the name "Lutz" mentioned a lot. Is he a CEO or major officer of GM? The reason I ask is that I saw the new Edmunds newsletter, where they rated the new Impala. They said that there's a new 2006 trim level, LTZ, and I wondered if he named it after himself.      Also, I looked at the discounts on the '05s and they look more generous this month. $2500 rebate, plus $1500 if you can prove ownership (I'm not sure if it's just current) and $500 for auto show promotion. I am not sure if that last one is just for cities having the auto show, though.      So you probably will be able to pick up a good deal on the '05s, hvan.

Bob Lutz is the Vice Chairman of GM, but he is in the spotlight all the time....he is the current architect of the new models, he's 72 years old some like him/some hate him.....he's not afraid to speak his mind...worked with many auto companies in the past. The LTZ model is being dubbed the LuTZ model after LUTZ....however the LTZ moniker was used on the Chevrolet Caprice Classic I believe 1993-1996. I could be wrong on a the exact years. It was the top of the line Caprice....wasn't a big hit because the Caprice was winding down at that time...and ended production at the end of the 96 model year...I find using these letter designations confusing.....previously the Impala LS was the top of the line, now its the base model....why do they need four models including the LT?..and as I said the LTZ used to represent the Caprice Classic......they have sort of gone off track to those that follow the Impala designations, but I am sure it will do ok!

There was also a Lumina LTZ, and I think TrailBlazer LTZ. It's the "high-end" non-sporty model (that ends up as SS.   Lots of past Chevys have been LS, LT, LTZ, and SS...   --Robert
