The Ocean by Led Zeppelin

The GMC-Detroit Diesels were 2-strokes that had no intake valves. Instead of intake valves, the cylinders had holes all the way around, so the block was basically an open chamber. The supercharger was bolted to the side of the block and blew into the open block chamber. As the pistons moved down, uncovering the holes in the cylinders, also under the power cycle, the exhaust valves opened, the supercharger filled the cylinders with air, at the same time blowing any remaining exhaust out and just like any internal combustion engine, air was compressed as they traveled upward after the exhaust valves closed. Unlike modern supercharged engines, the Detroit Diesel just used the supercharger as a fan to blow air into the cylinders. Ofcourse, as they were gear-driven, the gearing could be changed to provide extra air. So, to get even more air into the cylinders and provide a bigger bang, turbochargers were often added. On a side note, as GM was in the business of also manufacturing train locomotives(Electromotive Division), they incorporated their 2-stroke diesels also. 2-stroke diesels remained a fixture in train locomotives forever. Now, because superchargers use power to operate, they are also a drag and take power away. Enter the turbocharger. As the locomotive diesel is running fast enough, the supercharger would be bypassed and no longer drawing power and the turbocharger would then be pumping all the air into the engine(also compressing air) therefore the extra power boost came for free and used no horsepower(theoretically). What made the Detroit 2-stroke diesels so great? They had a flat torque curve and worked well with automatic transmissions. It was also a reason that charter buses could get away with just 4-speed manual transmissions, whereas a 4-stroke diesel needed atleast 5 speeds. On the GM transit and urban-suburban coaches, they often had a transmission known as "Hydraulic Drive". There was a 1-speed gearbox which provided forward and reverse, but the real work was done by a torque converter, operating like a Buick DynaFlow automatic. But, the difference was that the HD transmission had a lock-up clutch which basically bypassed the torque converter giving a 1:1 mechanically linked gear ratio. It is not uncommon to find Detroit Diesel configurations of 3, 4, 6, V6, V8 and V12.

It is a BEAST of a truck/wagon! Looks awesome! 😎

Great video as you always do. This is a customized truck. I used to own a 1947 dodge civilian 1/2 ton and would drive it in the Mojave desert area. It never failed me. I love your videos of orphan cars, specially the Kaiser and Frazer ones that you made. I really appreciate the work you do. Keep up the great work and research you do . I admire a young man like you that appreciates old vehicles and keeps their history alive. Thanks and make many more coming our way my friend.

Wow, this 46 Dodge Power Wagon is a fascinating vehicle!!! Your review of this unique vehicle is very good!!! Thanks for sharing this interesting video!!! 👍👍🙂

What a unique vehicle! I'm glad you featured it, Jay.

Have always liked the 40s dodge trucks. Good job getting to this one.

You have some cool friends if they drive things like this.

5 stars 😀

A manly truck for manly men! Wow! Love it.

I think you meant a WIDE turning radius. If you have to do a lot of K turns

So the 371 the only difference between the aluminum block and the Casteel block was wait they had the same horsepower rating. The supercharger does not increase horsepower it's a Scavenging engine though supercharger simply move the exhaust gas out of the cylinders the only Power additive is the turbocharger. You're looking at about a whopping 120 horsepower

Thank you for not calling the military version a "Power Wagon"--I believe the Power Wagon with the original semi-military body was NOT built after 1968--yes ,they produced a 4 x4 truck called the "Power Wagon" for years afterwards but it was just based on the civilian pickup body

The grille looks like the bars in a jail cell.

As I understand it, many WW II Power Wagons and their variations would have another 'life' in the IDF. Eager for arms... the new state of Israel would 'paw through' the junk yards of Europe (early 50's) looking for military transport that could be taken back to Israel, refurbished and re-purposed. In films of the 1967 Six Day War you will see many of these trucks in use. Finally France (for a while) would become Israel's principle arms supplier. However, many WW II surplus 'goods' would appear again in the hands of the IDF as France handed off its remaining U.S. Lend/Lease 'stuff' to Israel... as well as selling new French arms to them.

I think that engine is actually a 3-53 if it hasn't been changed out.

Do you have any videos on any newer model Dodge Power Wagons? Thanks.

You should almost need a stool Or step ladder to get in or out.

Hi Justin, you and I know that Chrysler owns Jeep at this time, but in the mean time when American Motors purchased Jeep from Kaiser Motors (second owner of Jeep) and became "AMC" (at that time) American Motors advertised "we wrote the book on 4 wheel drive" well I don't think so. Dodge Power Wagons where all ready active in WW 2 before the Willys Jeep was used in WW 2. Willys-Overland Motors (first owner of Jeep) By the way, the Detroit Diesel engine on the truck that you profiled is most likely a 2 stroke diesel Vs. a 4 stroke diesel, as most Detroit Diesel engine(s) are 2 stroke. 2 stroke diesel engine(s) must use a super charger to force the air/fuel mixture in to the cylinders and the spent exhaust gases out of the cylinders by means of reed valves located at the bottom of the cylinder walls (no overhead valves on 2 stroke) as the turbo charger is an auxiliary. Please reply. Dave...

Seems strange that the 3 oil filters are so exposed under the truck. If you took this off-road, they would be the first thing to scrape off? It has a great look though. I recognise it from somewhere, probably war surplus in Australia? I've seen some very unusual wartime trucks, especially, and 6-wheel drive seemed popular in particular, though perhaps they were the keepers? The plainer, 4-wheel drive Dodge's, used to be in all the parades on ANZAC day.

You're wrong they stopped making a public cars from 1942 to 1945

Where did the owner get the wheels?

Beautiful more beautiful than new cars ugly made from blastic and losers I wish made new cars like old style from iron and glass lights mechanical parts simply with little new style

Should have stopped right here., In evolution.

And it really looks like it's used off road a lot, lol. Useless.
