I just can't slant .....

totally agree with this post. ^^^ All the "quirks" (if you will) can be easily worked around. I can't fathom why they put the exhaust port next to the intake port in the head, such a power killer!. I just think ... "why didn't they stand it up after the early A era ???" Then, they could have redesigned the head and put the exhaust and intake on opposite sides! More room all the way around the engine! And the last few years only in trucks and still they left it a leaning.. lol

I reckon by then it was more of a trademark than anything else. But, I will say this. Since they never made a different head, it's a hard comparison to make. The bore size can only stand "so much" valve, so how much more head could the engine have stood? IMO, they got it dead right for what they intended its use to be.

I think the slant was a killer robust engine when it first came out for it's time. The head improvement, in my eyes, wouldn't be so much in valve size but in getting the exhaust port away from the intake port. This would have helped in many ways. First, horsepower for more than one reason. Second, heat soak. Third, the intake wouldn't bolt to the exhaust manifold (crying out loud!! lol).

Who can argue? Although I've never had a problem with a thermostat, I can see where someone might think the distributor is "awkward", especially if they've not figured out that the best way to work on the distributor is to remove it. I can have mine out in less than five minutes and that's on Vixen, where the room is pretty tight on the passenger's side. The manifold arrangement is really not worth complaining about, since it's pretty much set in stone. Again, I can have the intake and exhaust laying in the floor off Vixen in 30 minutes, maybe a skosh less. But of course, all of the studs are good and have high temp grease on the threads so they will not break off. The plug tubes? There are red silicone tube seals available that last several plug changes, so there's no problem there.....unless you leave the metal gaskets on the plugs. Then they do tend to leak a little. I will agree on a point you didn't make. Everything about the slant 6 is from a different era. Just look at the crankshaft. Looks like something out of Fred Flintstone's car. The whole thing defies logic, but they run and keep running.

Crank looks like many other 6 cyl cranks to me, except only 4 mains.
 
I can see the 225 that should have been that never was....
standing upright, 9:to1 compression, head as I described above with exhaust on passenger side, intake on driver's side (power gain for sure in flow and heat), roller cam that has a touch more lift than a broom stick.. lol. This would make more power and torque without surrendering anything that the 225 was known for except...... that slant :)

P.S. - And oh.... stand the engine up, not the thermostat!! LOL :D
 
I’m with you 318willrun. When we were searching for my first car my dad said no slant 6s. He said you’ll want to get a V8 in no time and wasn’t interested in doing the swap haha. So for over 20 years I’ve had a 318. That said, I love seeing a clean slant. Love the turbo slants. Love the Clifford stuff, seeing them built, the headers across the bay, etc, but for myself? I can’t slant. But not a knock at guys with slants and I’m as happy to see one at the cruise night as any other Mopar.

100% agree with everything ^^

Yeah, I never have liked that design. Totally counter intuitive for power production, I don't care what the experts say. How much manifold heat does something need for "good atomization"? The intake is right on top of the exhaust. I don't think they needed to be bolted together and least of all be blasted from underneath from the exhaust manifold. I've had the heat blocked off on the original 170 and the now 225 ever since I've owned it and it runs just fine. In fact, it runs much better, because it eliminated heat soak. No sir, the cooler the air fuel charge is, the more power can be made. I would just have to agree to disagree with anyone who thinks opposite.

I personally get more excited at a car show seeing a real clean slant or modified one than a regular V8.

I like the Slant for what it is. It was built for efficiency, and it's just kinda cool to see it as a piece of history. I love how easy they are to work on, and they cruise pretty good too!

How many times have you torn your truck apart now?

Completely? Only once to yank the slant and drop the magnum. But I’ve had the trans out of it 3 times. It’s all good now after 2 rebuilds. Why? Is there some correlation you’re trying to make between having a V8 and how many times a vehicle needs to be “torn apart”?

plenty of room if I wanted to go 500 or 518. I doubt I will though, truck just won't see enough service for my to justify that swap. My '13 Ram does all that for me.

I have a '12 and it's, well, blah. Other than that it has the Sirius radio with the "classic vinyl" station and no commercials which I can add to anything . . Maybe if I had a hemi instead of a 4.7 I'd think different.i can't wait to get my 80s trucks back again

The turbo slant was running I think mid 12s last weekend. Looked like a ton of work.

So I guessed at the weight but at 3000lbs that’s right close to 300hp. I’d say that’s getting pretty sporty for a slant.

You are right, the manifolding design been around since at least the 1920s when they needed the carb heat. Long runners certainly a band-aid, a poor one!

The Aussie 6 cyl head sounds like what you're talking about. Having never seen one and no knowledge about it, not even year of intro, is that what happened to slant upgrades instead of here?

My 2013 has the 3.6 V6. It ran 15.22 at 90 mile an hour and gets between 25 and 28 miles per gallon depending on how it’s driven. And 85 mile an hour on the interstate is a snap for it. Pretty hard to ask a D150 with a slant to compete with those numbers lol.

I too, I am not real good with the Aussie slant six

I’m hoping mine will run in the mid 12s on motor and high 11s on N2O and I’ll be driving it to the duct tape drags (So Cal to Tucson) in October and I’d really like to see 20mpg. I think with vacuum advance I can get there.

My truck is a 2 Wheel Dr., short bed, and weighs about 47 to 4800 Pounds. I hauled some junk and had to go over the scale. I reckon if my drivetrain was in a 3700 pound D150 short bed, gas mileage would increase along with obviously the performance. I’m really surprised more people have not tried to install the 3.6/8 speed ZF into the older D series
 
I think the slant is a thing of beauty and in its own oddity from the start to the finish is cool. I can certainly understand why some people would enjoy having them and working with them, because it’s fun, and its own realm enjoyable . But in almost every scenario, a car or truck or van with a V-8 is almost always worth more than one with a slant. I think the market kinda shows how the general public views all of this.
 
Ok guys.
I know some guys hate Scamps,.
Dislike green. And Dislike slants.
But if this was closer I would just add A/C and cruise slow.
