I am not a huge fan of Dodge, but you just can't beat Cummins. Check this out.

A lot of idiots in the comment threads :)

Word for the wise, if you a see a diesel and you can't hear the engine over the turbo spool, and its smoking BAAAD...stay away :D

That truck is probably twin turboed and fueled to the max on the verge of a melt down. Its amazing how much guys spend to make a B series do that :rolleyes:

Doesn't Ford own Cummins? I thought I read in some car magazine that they did.

Ford had some shares of Cummins at one time. They don't anymore.

Ford has always been in bed with Navistar for their diesels.

Also International is building trucks with Ford look at the LCF Cab overs and I heard the 650 and 750 share International engineering.

Ford has been with International since 83 so they have a long term relationship. Where as Dodge has been kissing Cummins azz since 88 if it wasn't for Cummins Dodge probably would have gone broke. Who buys a gas powered Dodge ?

Yeah, marketing is about the only thing that makes sales for the 5.7 Hemi. I'm sure it's a good motor, but it doesn't put out any more power than something from GM or Ford.

99% of all gas engines are "HEMIS". Semi-Hemispherical heads is all.

Sure, cummins are nice engines, too bad the trucks fall apart around them.

I don't care what you are driving, to run 11.50's in the quarter takes money.

That Cummins probably has atleast 10 grand invested into it to do that.

As for hemi engines I seriously doubt the new ones are like the ones of the 1960s-70s those were decent sized engines. I think the displacement was 426 cid. Dodges tried and true engine was the 318 made for years the problem with Dodge in the early years was the weak ignition and gear drive starter. Dodge never did build a truck that would last the old ones had good driveline but the cheap sheet metal would fall off.

If it wasn't for the Cummins option in the Dodge trucks I really doubt they would have many sales otherwise.

Yep. The fuel injectors alone retail for $1300.

As I said, going fast cost money :)

A point of clarification. Most modern engines are actually "pentroof" engines, using the pentroof combustion chamber design.

A hemispherical cylinder head is limited to 2 valves, as adding anymore does not allow you to retain a true hemisphere shape.

When dual overhead cam engines started to become popular in the late '80s engine designers modified the hemispherical design to the pentroof design. The combustion chamber is shaped more like a inverted pyramid instead of a smooth hemisphere. This allows the use of four valves (2 intake, 2 exhaust) for more flow and better engine control.

Hemi Head:

Pentroof head:

An interesting thing to note is that the new HEMI does not use a hemispherical cylinder head despite its name. However, it doesn't use the Pentroof design either, as its a 2-valve per cylinder head. Its pretty much just a conventional cylinder head that resembles what you would see on a small block Chevy engine. Funny what the guys in the marketing department can do.

Thanks for the info Dirty Water.

That engine in the vid. is obviously not stock, but I have seen some of them that are close to stock haul A$$ also.

Uhh no... they don't fall apart. I have several... one w/ over 300k that works everyday. Hopefully I will get 400k out of it... really can't beat that.

In the end, it's still a Honda CRX. I saw a video of a nicely done Mazda RX7 with an LS1 in it. That was an awesome car. I think he was pushing 1000 horses, pulled rubber in every gear.

Before i moved to omaha, i lived in alaska for 5 years. I drove a 12.5 second subaru as my in town vehicle. I would get whooped on all the time by big lifted trucks. All manufactures. The diesel power market is inase their. Diesel is actually like 50 cents less a gallon then gas. Their is a post somewhere of a duramax that runs 11's. Its a cool video.

I'm sure there are some street driven 4x4 D-Max's in the 11's but I honestly am not aware of any street driven, 4x4, Powerstrokes in the 11's? I know of the 2wd Powerstrokes in the 11's but not any 4x4's.

Salesman at a local International dealer said Ford/International are in "somewhat together" on the trucks to a certain point. They are built in Mexico.

They both have the Navistar motors I think.

The Ford medium duty trucks aka 650-750 don't use the 6 cylinder international engines they still us Cummins and Cat and the 365 aka 6.0.

Ford used to build good heavy trucks the Louisvilles were top of the line.

I know a guy that had a 11 sec Dmax and it was his daily driver and plowed with it.
Know another guy in my area that has a Dmax, running 13.5...last time I saw it.
My buddy has a cummins...modded heavily and can't even think about keeping up with my Dmax...all he sees is smoke. I ran a 14.8 in the fall and should be in the low 14's in the spring.
Cummins are very easy to mod, especially the 24 valve and 12 valve, but the Dmax's are even easier.

I've never seen a larger ford (650 or 750) with the VT365 or the 6.0L or what ever you want to call it.

I think Ford should try putting a 6.8 V-10 or designing a Big block V-8 for them to compete a bit with the GM Topkick trucks.

Yup, 10 million in the 11's, a few even better.
