I hear the term "slant-six" sometimes. Does it mean the same thing as inline six?

 

the slant six is a dodge inline six, but slanted part way on its side...i don't know the pro's or con's to the dodge slant six, just that it is an inline six, just slanted instead of straight up and down...

Yeah the slant six looks like one side of a V-12 engine. I had a slant six in a '64 Dodge Dart--first car. Push button automatic shift selector too.

 

The slant allows for a long stroke inline in a low hood vehicle.
The slant also permits a long intake runner, something chrysler was doing alot of when the slant was designed

 

One of my friends in highschool had a Valiant with the 225. Never changed the oil or tuned it up or anything. He wanted to kill it and put a 318 in. He added oil to it when the oil light came on, but never changed it. After highschool and college it still trudged on, stone reliable, untill one day the car got rearended and totaled. Still started and ran, though. Do that with a V6.

 

The 225 slant six had an impressive 4.125" stroke! I don't know of too many other engines with that amount of stroke. Oh wait the 292 generic motors produced had that also i believe. Anyway Argo right, you cannot kill these engines much like the 300

 

With that long of a stroke it must have a small bore. Does anyone know some hp/torque specs for a 225?, curiosity strikes me.

 

I think its bore is 3.4"

 

i had a 300 srtaicht 6 in a truck i demoed , got the truck (blown up) took it home battery in it and it ran on 5 cyl i t had a dropped valve so i ran out of time and demoed on 5 cyl finished and pulled the (stilll ran but barly pulled itself) lifter cover off and pulled the push rods out and i think it was 3-4 lifters that were still good i replaced the rest and ran it the next year we blew it up then it got so hot that it thew 2 rods (forgot the oil plug fell out so no oil ) commin off the track

 

In the late 60s/early 70s there were three sizes of the slant six: 170, 198, and 225 cid. All had 3.40 bore. Strokes were 3.12, 3.64, and 4.12.

 

The slant six was a good motor, but the 300 is nicer to live with for the following:

1. The 300 has more displacement for more power.

2. The 300 has 7 main bearings and the slant six only has 5 mains. Therefore, the 300 is smoother.

3. The slant six is more cold-blooded than the 300. I think this is largely due to the long intake runners on the slant six intake manifold. The idea was for the slant six runners to all be about the same length for more even distribution of fuel. However, when it is cold, those long runners can cause some of the gas to condense inside the runners.

 

one of the slant's problems is that the oil filter screws directly onto the oil pickup tube.
If someone overtightens the filter or doesn't oil the gasket poperly you can actually rotate the oil pickup too close to the crank when removing a filter. the crank counterweight will slowly wear a hole in the pickup tube while making a noise that is very simular to its mechanical valvetrain.

 

The distributor on the 225 slant six is really hard to get to because it is beneath the slanting block. My first attempt at changing points resulted in dropping a screw down into the distrbutor housing. This was in the parking lot of a store, duh! So I wrapped a few feet of wire around the shaft of a screw driver and had a friend hold the ends of the wires to the battery posts while I fished the screw out. The wire got really hot, but the screw was retrieved.
The 225 slant six was a great motor! ...Terry

 

I heard the Ford 300 six was too tall for the new truck style in '97 so they dropped it. Well there were emissions problems too. But now it should fit the new trucks. Anyway, maybe they could have slanted it and fitted it in. Or better yet, bring back the old 240 which should have had nearly an inch less height.

 

Pity the things that happen to engines because of body style changes. There used to be straight 8's along while back.
