#110 of 3460 Re: Impala 3.9L - OHV ? [frasierdog] by 1487 Jan 12, 2005 (4:31 pm)
Replying to: frasierdog (Jan 12, 2005 7:42 am) I don't know why you would think the Impala was going to have a DOHC engine. Besides, the 3.6 used in the Lacrosse wouldnt even make this a faster car. The Lacrosse only has 225 lb-ft of torque which is less than the 3.9 and only slightly more than the 3800 and 3500. It's still a modern engine in spite of being OHV. Ford doesn't even have VVT on the duratec used in the 500 and the VVt Duratec in the Fusion/Zephyr makes only 210hp. IF you want the 3.6 you better get a Lacrosse or wait for the new saturn.

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!

Replying to: stormdavy (Jan 12, 2005 2:59 pm) That does look cool! Can you do the front also? Give it a nice grill?   GM should hire you as a designer!!!
#113 of 3460 SS Logo by hvan Jan 12, 2005 (5:07 pm)
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) Hi hvan,   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. Replies to this message: hvan3 (Jan 12, 2005 11:13 pm)

Replying to: bh628 (Jan 12, 2005 5:20 pm) Yeah, the rain was pretty bad. I figured it was the best time to go see the auto show. The more rain, the lesser the crowd at the show.   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.
#116 of 3460 Why a DOHC and not OHV? by frasierdog Jan 13, 2005 (8:23 am)
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.

#117 of 3460 DOHC OHV/frasierdog by charts2 Jan 13, 2005 (10:12 am)
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"!!
#118 of 3460 DOHC OHV by charts2 Jan 13, 2005 (10:15 am)
Correction on post #117....it should read Chevrolet has never made an DOHC engine...
#119 of 3460 Umm, ... by jae5 Jan 13, 2005 (11:25 am)
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?
