Roller followers, yeah. Rockers that can "pop off" like a ball-stud Chebby? Nah. Sorry, that kinda casts the whole claim into doubt. Its backyard mechanics like yourself Steve that keep me busy. The 4.7L does have ROLLER ROCKERS part #53020742AC and so please make sure you know what you are talking about before your next post. |

You should listen to a Toyota or Honda 6 cylinder engine. |

I took that to be his meaning too when I first read it, but, on reflection, I think what he meant was that - yeah - it has rockers - but not the type that can pop off. IOW - I don't think he was meaning that it didn't have rockers. |

The 300 w/3.5L has a 5 speed. Early 06's had the old 4 speed. It's probably not as quiet as the Hemi because it has to work harder moving the 4000lb car. Plus you hear different things. A decibel meter can say one engine is |
|
I had 2 test drives with the 3.5L and on one occasion it made a couple of extra click sounds immediately after starting. |
|
Is this normal? It went up to 2000rpms during starting and settled down to 600rpm after a few minutes of driving. |

A head with no moving parts, solid lifters that you could actually adjust, easy to work on, relatively good mileage for their period of time(I get around 20 consistently). I had a 225 slant six in two cars: a 1970 and 1964 Dart, yes it was a great engine, but still, those old flatheads would just keep running and going with regular maintenance. As you can see, I am a little prejudiced! |

As you can see, I am a little prejudiced! As the Geico commercial says, "its kinda like the queen asking if you want to have dinner at the palace or at the castle. Either way, you're having filet mignon." I can't disagree TOO much with you, because the flatheads are certainly rugged. And I love the fact that they're as smooth as an electric motor in the way they pump out the torque. There's a 50's vintage "cherry picker" crane in the materials yard at the lab where I work, powered by Chrysler industrial flathead and fluid drive. Still in regular use any time its needed. There are also still a lot of airport tugs running around with them. But on the other hand, the slant-6 and 318 do have some longevity advantages. Not the least of those is a full-flow oil filtration system which the flatheads lack (flathead Chryslers are often fitted with full-flow filters, but only a portion of the oil pump's output passes through the filter on each cycle through the engine). The later engines also have stronger crankshafts (particularly the 318, which is both shorter and stronger). And just empirically, my experience is that you see more 300,000 mile plus 318s and slants than you do flatheads. Finally I respectfully disagree that solid lifters are a longevity advantage, I think hydraulics have the advantage there because you never get burned valves from a valve clearance that was either set to tight or became too tight due to valve stem stretch.

Plus you hear different things. A decibel meter can say one engine is quieter, and yet it can seem louder to most people depending on the type of noise. The Hemi has a pleasant 'burbly" v8 exhaust note, but all v6s have a rasp that most people find grating. The 6.2 liter Hemi in the SRT-8 has a deliberately LOUDER exhaust system, yet I find it the most pleasing-sounding of the 3. The 5.7 is a bit too muffled, the 3.5 is, well, a v6. I had 2 test drives with the 3.5L and on one occasion it made a couple of extra click sounds immediately after starting. Not very descriptive- what kind of "click" sounds? On some Chrysler products, you can hear the evaporative emission control solenoids clicking around doing their job after startup. And on most, you can hear the variable duty cycle solenoids in the transmission working when you select a gear. Is this normal? It went up to 2000rpms during starting and settled down to 600rpm after a few minutes of driving. It should settle out within about 20-30 seconds of startup, just like every other modern computer-contrlled EFI engine does. |

In article <pan.2007.05.17.19.53.15 (AT) yahoo (DOT) com>, General Schvantzkoph <schvantzkoph (AT) yahoo (DOT) com> wrote: performance, not even cars that cost 20K more. Negatives to fuel mileage: Weight, wind resistance, AWD, and particularly in city driving engine size. The engine is a variable displacement engine so it's not nearly as inefficient as it could be. I'm not sure about the aerodynamics, the Concord certainly looked more aerodynamic then the 300 but the 300 is fairly low so it might not be as bad a problem as it appears. AWD hurts a little but it's an absolute necessity, I wouldn't even consider a car without AWD. If you live in a sunny state then RWD is a good choice, but I live in New England. The hemi variable displacement is not effective in city driving. The 300 obviously is not as aerodynamic as the Concorde and frontal area is a big factor. Low ground clearance won't help. Yes AWD is important if RWD is the other option. I go everywhere with FWD, lots of winter driving to our western ski hills. |

The 300C is one of the best cars on the market for the price especially since it comes fully loaded and you get autostick Mercedes transmission, steering and suspension components. It really is comparable to cars selling for $20K more. Especially suitable for lower mileage drivers who appreciates a quality ride with all the options. |

It is a good value car of it's type, but not what the consumers want in adequate volume now with the increasing gas prices. Poor Chrysler is still trying to sell new 2006 large vehicles here at about 30% off list: Pacifica, 300, 300C and large engined large trucks. It will soon be time for the 2008 models and those 2006 models are looking stuck in the dealers hands. I hope the write off of these models doesn't have to be done again at a lower value. The prices are low enough for me, but they are not the vehicle I want. |
