A little food for thought on the V10

The Dodge Truck V10 Engine (1994-2003)

 

Funny how a whole bunch of things that article says was "before it's time" already existed in the Ford 4.6 modular that debuted in 1991 in the Crown Vic.

Crankshaft-driven oil pump. Distributorless ignition (DIS). Y-block configuration where the block extends down below the crankshaft center-line (ala the Ford FE 332/352/360/390/428/428 line that came out in what, 1958?)

Interesting.

 

Remember that Chrysler lives in their own little world so in their mind it was before their time. :lol:

 

Marketing speak. They did it for the same reason Ford raved about all the fancy new technology in the 6.7 PSD, like CGI blocks, twin scroll turbo chargers, aluminum heads, and SCR urea injection. All of that had already existed for quite some time. Even the reverse flow heads aren't anything new.

 

Ain't that the truth. Like their current "Hemi". The 4V modulars are as much of a "Hemi" as those engines are.

 

The new Hemi is actually very close to a hemi engine. Chrysler filled in the sides a bit to reduce combustion chamber area so flat topped instead of domed pistons could be use.

Hog out the bits on the side and you'll have a true hemi head.

 

Not trying to be an ***, but Chrysler used dis in 1990 on the 3.3L V6, and GM used it in 1987. So by the time the 4.6L even came out, the other manufacturers were already using it, and the Ford truck motors were no where near as advanced as dodges V10 at the time it came out. But arguing about this is pointless, the imports probably did it all first anyway.

 

I've worked on a '99 Honda Accord V6 VTEC that still had a distributor!

 

Very true, the import part.

but do you consider "distributorless" as "no distributor cap" or nothing in the distributor hole?

 

I just don't see an advantage (compared to other current designs) to mopars current "Hemi" which isn't even closed to their past head design they brag up. Its good marketing for people who do not know better though. I can't blame Chrysler though for trying to take advantage of the Hemi name. The pic above shure looks like a machined OE head.

Real "Hemi" head

 

There have been people that have hogged out some of the sides of the chambers and the result is very very close to the original Hemi heads. The had I pictured has just been lightly polished. Still has the original combustion chamber shape. The head even has the dual rocker arm setup like the original Hemi.

Here's is another picture of one:

They wanted to keep the engine somewhat compact so that required a pushrod design. So they decided why not and go with a hemi-ish design. The valves are perpendicular to each other, so total air flow is good, and flow on per port basis is also good as its a very straight shot to the valves from the port opening.

 

I suppose it is somewhat hard to see properly from the pictures.

 

Actually the first year that V-10 came out, it made more torque and HP than the Cummings. And also it has two coil packs, one fires four cylinders and the other fires six. And they both cost the same as one COP on a 6.8. Im not a Dodge guy by any means but they did it right with that 8.0. Plus the power band is 1200-3000 much like a diesel. My 6.8 ford likes to rev up to make good power. I love my Ford V-10 but when I was shopping for a new truck, I was looking for a V-10 Dodge as well. Just found the Ford first. No regrets though.

 

8 litres of antique.

 

Yup, and a tragety that they discontinued it. I love that the whole engine is cast iron too. Just a pure workhorse.
