You are in the Chevrolet Impala Forum. Your Hosts are pat & karens
| Those lights on the back might be just a little more then I would want but people would sure recognize this as an IMPALA!, not a camry/accord!.....The middle lights should be the white back up lights! Make the lights 90% that size and you have my vote!!....send this to Lutz, maybe its not too late! | |

One thing I noticed at the show is that there are NO SS logos on the vehicle. Was this an oversight? While taking pics, a lady walked by me and told her husband that the Impala looks like a "Japanese Import". Her words, not mine..... |

Replying to: hvan (Jan 10, 2005 2:47 pm) I had you in mind this weekend also, wondering if you were going to be going to the Auto Show in that heavy rain! Did you borrow a boat for the drive up from OC??? You are really a car fan, to brave that strong rain! Thanks for all the pictures.

Replying to: bh628 (Jan 12, 2005 5:20 pm)  I'll be going to the auto show again this weekend. A friend of mine is looking to buy a new car. He wants to dump his 540. I'm trying to convince him to get either STS, TL, M35/45, or 300C. |

Why would anyone want a DOHC and not a OHV design? Simple, it will be quieter, smoother, produce less emissions, lighter, better NVH, breathe better at higher RPM's, rev quicker. And yes, new DOHC designs produce more bottom end torque than old OHV designs. The only reason to hang on to OHV is cost. OHV is cheaper not better. Ford will be release a new line of engines based on the 3.5L VVT DOHC design starting in the 2006 model year.

| Chevrolet has never made an DOHV engine in its 93 year history and done quite well in selling cars/trucks.....With a complete revamp of new engines in 2006 all OHV, I guess you will have to move on to a car/truck company that will satisfy your concerns......you won't find it here..."ITS AN AMERICAN REVOLUTION"!! | |
| Correction on post #117....it should read Chevrolet has never made an DOHC engine... | |

What about the DOHC 3.4 based on the Chevy 2.8/3.1? Believe this engine was in the W-Body Cutlass and Lumina Z34 in the early to mid-nineties. I agree you can't really count the ZR-1, due to it being a Lotus-design and the engines were built in-house (were built by a marine (boat) shop, correct?) And frasierdogg, you forgot to mention that you have to REV those DOHC to the high heavens to get that high-torque number, along with the horsepower. Whereas the ohv make torque at low-mid rpm, mostly building right off idle. I will agree that there are a few DOHCs that start making decent pulling power near-right off idle and have o.k. mid-range torque, but they are few and very far between. And who wants to buzz their engine to the high side 5-grand to reach that pulling power? You're points are o.k, but not really true in terms of NVH, smoothness, lighter (which I don't really see given the add weight of chains/belts, extra cams, gears, bigger heads...). Just because it's OHC doesn't automatically make an engine smooth and a NVH champ. And I won't mention the cost when you have to replace cams, possible stretching of the changes/belts, cost of changing the timing belts, damage if the belt/chain goes. It's almost like saying OHC is new, it MUST be better, when in fact it's as old as OHV, heck older than what's considered the "modern" OHV!! Just because it's cheap doesn't mean it's not as good as OHC. 3800 series II, gen III and IV small-blocks aren't bad.:> If the OHC is sooo good, how come it took Ford over ten years to boost the hp from 210 to 300 for the 4.6?

Replying to: jae5 (Jan 13, 2005 11:25 am) That is a really old stereotype. Yes, it may have been this way in the first days of DOHC, but in today's world, its more than 'few and far between' that DOHC engines have good low and midrange torque. Witness the Camry 3.3L: PEAK of 240lbs  3600 RPM. The Malibu 3.5 peaks but 400 Revs lower, and with 20 fewer pounds. Or, we can use a Honda as an example. The Acura TL 3.2L produces 90% of its torque peak of 238 foot pounds by 2500 RPM. That means 214 pounds are on tap at that point. Is that not good low-end grunt? ~alpha
