If one counts the cam lob as one part and valve as a second part, then a DOHC engine with 4 valves per cylinder (the usual case), has eight valve train parts per cylinder and at least two, if not four cams per engine. The pushrod has the valve, lob and the pushrod and rocker arm for a total of four parts per valve. However, the pushrod engine has half as many valves per cylinder, so the total parts in the valve train are the same. But there is one one cam per engine, so a pushrod engine has fewer expensive parts.

Your STS's engine is tuned for high speed performance and does not have much low end torque. The 3800 is tuned for low end torque and has little power or torque at high engine speeds (over 5500 RPMs). My supercharged 95 Riviera and my 98 Aurora had very similar performance. My 2002 Seville, tuned for low end torque, was very similar to the Riviera for performance. The Riviera's supercharger made icy roads much more difficult to start up on.

More reliable? I have 2 3800s in full-sized comfortable cars that get great gas mileage and don't cost me double for service in a foreign car store's service department for repair let alone piled on maintenance mandates from a dealer who sold me a totally reliable car but seems to think it needs constant over-servicing and replacements to keep it 100% perfect?
 
I'm not sure where this world commission is that determines what is out-dated and what is world standard choices. I want a car that has lots of torque and doesn't have to wind to 5000 rpm before high torque appears and then it's time to shift again...
 
As for Japanese cars don't break down--I have been collecting complaint posts asking for help with those Japanese brand cars failing their owners in my Watched Items page. I can link to some of them if lykourinou needs help finding them.
 
Sometimes I realize that people live in the past and think they can still hang problems of the 80s and 90s where a higher problem rate occured for some owners of US brand cars rather than stepping into the current world where JDPowers ratings show US built cars on a par with the Japanese brands. Things have changed in the build of US brand cars; and things have changed in those Japanese cars.
Does anyone have a link to the JDPowers ratings. I have to look through lots of bookmarks to find the last ones I saved and can't find it quickly.

I've driven my fair share of OHV engines over the years, and I didn't find the low-end torque to be a "kick in the butt" at anything less than WOT, and even then the "kick" didn't last long. I don't think that's a good trade for the loss of rpm range, horsepower, and smoother power delivery.

I think that it can be said that a well designed pushrod engine will last just as long as a well designed DOHC engine. I also think that in the case of a poorly designed DOHC engine, the cost of replacing it when it fails will probably be twice as much as a failed pushrod engine.

the 3 of you must work for GM. I give up, It will make you happy to hear this so I'll say it.ok GM builds the most modern and most dependible cars in the world. The rest of the world is wrong for having standard intelligent keys with push button start on base models.
 
The rest of the world is also behind GM for having DOHC engines and independent rear supsensions. Although GM is starting to sway and build cars backwards. 2007 Buick Enclave DOHC engine, 2007 CTS DOHC engine.

I don't think I would agree with that either.
 
GM does have DOHC engines. Their 4 cylinders are either all, or mostly all DOHC designs. The V6 and V8 engines are a mix.
 
Intelligent keys are cute, but not needed for anything useful.

while I am not sure, I think that the SRX's (and CTS and STS) shocks can be replaced without replacing the strut. This would save money.

Hey, what about me? I gave up on GM and they will need to show vast improvement going forward before I go back to the below par offerings in recent memory. I wonder why they are bleeding at the bank? Is that the gold standard of the automotive industry?
 
Why is Porsche the most successful earner year after year? Because they make junk? They are rolling in the dough so it must be that their customers are "not in the know" regarding pride of ownership.
 
That pride is long gone from everything except US Trucks and the Corvette, IMHO.
 
If they keep offering CTS, Malibu, Lambda, Camaro products that prove reliable and strong enough to win back from the rest of the World, the tide will eventually turn back. Time alone will tell.
 
Pontiac needs to get rid of the "G" designation and Buick needs a car with a soul or die.

OW

"I want a car that has lots of torque and doesn't have to wind to 5000 rpm before high torque appears and then it's time to shift again..."
 
There's still no substitute for CUBIC INCHES--as opposed to litres. The mid-50's to the early 70's were the glory days for those kinds of cars. The ultimate would be a 1970 Buick Electra with a 365 HP 455 driving a 2.56 axle ratio--loafing along at about 1,800 RPM at 60, it could be kicked down to second and blast to 75 with no strain whatever at 15 MPG--those days and engines are gone for good. The engines were still large into the 70's, but they became strangled with emissions gadgets. I still keep one on hand, 'tho--I've got my 4th '77 Mercury Grand Marquis in 23 years. It has a 460 with a 2.5 axle ratio--only 202 HP, but the torque from the displacement is incredible. Just by default of their size, these engines were virtually indestructible--they were designed to power motor homes and trucks. Placed in a 4,700 lb. chassis and running around 1,900 RPM to move a car is like they're not even working.
 
If the coming trend over the next 10 years is indeed to smaller engines to meet mileage requirements, then we'll be back to screaming little four cylinders that will work their hearts out like they did in those hilarious Castrol ads back in the 80's. High specific horsepower can indeed be gotten out of little engines, but they can't make the torque that gives you that satisfying feel of effortless performance.
 
The single worst mistake Cadillac ever made was in placing that disgusting 4.1 litre engine with 125 HP in the full size chassis--a chassis that just three years earlier had 425 cubic inches. You literally had to go back to the late 40's to find performance that was as sluggish as those cars--'49 six cylinder Chevy territory. I remember driving a couple on used car lots just to laugh at them. Cadillac lost so much momentum with that boondoggle, plus all the other GM blunders, an entire generation only remembers Cadillacs as trash. My frame of reference is the Cadillacs of the mid-50's on--cars easily the equivalent of anything BMW or Mercedes can produce today.
