I was thinking about it the other day and here's a list of the cities I've worked in as best I can remember.
Harbin, Yantai, Shanghai, Beijing, Nanjing, Suzhou, Fuzhou, Xiamen. There may have been a couple of others. Some of the guys in my team got as far west as Urumqi but not me. I got to go to Harbin in the winter. Everyone assumed I was Russian since it's so close to Siberia.

I was working for a company deploying optical fiber and telephony equipment.

I went back a few years ago and the place has really changed a lot. Cars everywhere and not nearly as many bicycles.

Where are you based?

Cheers
Mike, I'm here in Zhuhai, which is in Guangzhou, just across from Hong Kong and within walking distance of Macao. Spent nine years in Shanghai from 1986 onwards building three aircon factories then on to Tianjin setting up a pencil factory. Spent time in Harbin, Shuafenhur, on the Chinese Russian border, Chong Quing and Hunan. Did three years expanding factories in Korea, Taiwan, Malaysia and India and now back in China working on my third expansion for a company engaged in making micro drills for PCB subcontractors. Lotta fun, loads of work, get to work my ass off seven days a week, but still loads of fun, you know the drill, it never ends.

Cheers, John, AKA, tin-man

Not to get into the Ford vs Chevy fight, but can anyone tell me if an engine from the Engine Masters competition ever saw life under the hood of a running car? I'm genuinely curious as to whether one of those laboratory bred monsters could actually function as an automobile engine.

Well, that's certainly arguable. There are several folks here on CC who would be very disappointed that a REAL 427 sideoiler wasn't under the hood.

I think Patrick, after he finished picking the Maine lobster from his teeth, would be very upset with a SBF. :LOL:

I should be safe yuk yuk. I look at it like "family". 427 FE sideoiler is the twin brother to the original. 427 FE centeroiler, a brother to the original. 427 SBF, a step brother to the original. LS7, sister to the step brother's girlfriend.

How many of those engines actually contained any Ford parts? Most of them are built from aftermarket parts that have been designed around a particular basic design. About the only thing common with the original engine is the placement of various bolt holes.

I did some time in Macao too but only at the Casinos :MECOOL:

I know what you mean about working your ass off. I did most of my travel in 4 week blocks. You fly in, work like mad and then go home. I used to be away from home about 6 or 7 months of the year. Too difficult now with having a family so my trips are only a week or so at a time and only a few a year. I've done a lot of work around the APAC region over the years. Worked in the Philippines, Indonesia, Malaysia, Thailand, India and Japan as well. Seen some interesting places in my travels and others I never want to go back to.

Cheers (Gan bei)

Only if you don't know what you're listening to, or better yet, what you're feeling as the sound waves hit you. But, FWIW, most people don't and most people can't appreciate the sounds of different bells when they're not hearing them one after the other. But, ring one after the other and even the neophyte will say "you're right, there is a difference." See: http://www.clubcobra.com/forums/1024259-post11.html If you've ever taken your car to a show were there were deaf patrons, they will often times ask you to start up your car after seeing your big block engine. But not to hear it, but rather to feel it. And that be the difference between a small block and a big block.:cool:

AL427SBF 05-14-2011 10:58 AM
I'll have to do that A-B test myself just to "feel" what the discernable differences are. I would think your sidepipe setup and compression ratio would be the real players in the "feel" department.

So your car is emitting it's exhaust sound off the engine block rather than out of the tailpipe?

Both. Otherwise, a small block aluminum 427CID engine with the same compression ratio, horsepower, and timing events would send out exactly the same vibrations as an iron block FE (which they don't). An aluminum bell, with exactly the same cavity size as a larger iron bell, will sound completely different even when struck with the same hammer using exactly the same force.

That is correct. The natural frequency of an oscillating system is the squareroot of the stiffness divided by the mass, it works this way both for a bell and an engine block.

However if I followed your logic that the mass difference between the blocks makes a difference you can hear I must have given my small block car a deeper exhaust tone by eliminating rubber engine mounts and bolting the engine and transmission directly to the frame. This effectively increases the mass of the oscillating system by a huge amount (engine+transmission before, engine+trans+frame after).

Also what would happen to your car if you installed one of these aluminum toploaders? Would the decreased mass make it sound like a small block :p

I'd tend to say in that case the aluminum engine block would emit even more sound energy, as cast iron has much better damping capabilities. However compared to the sound coming from the tailpipe the difference in mechanical vibration of the block was absoltely negligible.

(which they don't).
You sure? :LOL:

patrickt 05-14-2011 11:52 AM
But everybody does not prefer the sound/vibration of a big block. Any more than all people like the sound of high winding smaller CID cars, the F1 cars, or all the variations in between -- Japanese fart cans are the worst, especially when they're faster than your Cobra. On my car, I actually went to additional extremes with the sidepipes to have them built to be "quieter." They are not terribly loud, in volume, as compared to a lot of big block Cobras. But you still feel the sound.;)

:JEKYLHYDE Your argumentation here is kind of highly unscientific

However be assured that I like the sound of a big V8 engine ;)

This one was not meant to be scientific. I was out for a drive a couple of years ago with my wife and there was a small block SPF along side of us that, seemingly, was as quiet as a new Toyota. My wife turned to me and said "Why can't your car sound like that?":(

Uhhh, me too.:cool:

AL427SBF 05-14-2011 12:35 PM
The problem I have with all of this "bell theory" is that you are not striking the outside of the block with a hammer :LOL:

Racer_X 05-14-2011 05:19 PM
That's when I'd of come home alone, after kicking her out of the car.

jk,

but " I " would do that. And my wife wouldn't say that.

I also have a good friend, who is a Mopar nut and who recently bought one of the hemi Challengers, hear my solid flat tappet system clackety-clacking away during a drive and he turned to me and, with an absolutely straight face, asked "Is the engine supposed to sound like that?" %/

Dang Patrick, keep your wife and gay friend out of your car and stop listening to their opinions! :LOL:
