To each his or her own, but there's absolutely no valid reason to keep it once it dies. I'm guessing that you can replace a /6 with a 318 or 360 for around the same price as rebuilding the /6. To me, different isn't good if it's not at least as good as what's more common.

But it costs a lot more in other upgrades to add the V8. It's not just the engine itself that needs to be swapped. It can be quite an expensive swap. Not to mention that you can often get another good running /6 for free or close to it, pop it in to replace the bad one, and you're done. Much easier and cheaper than a V8 swap.
 
da-- tx guy, I need a good slant right now!!!! bring it Mo, hunt some of these darned wild turkey that overrun the world here, and i'll give ya a case of beer and $50!?????
ya know the another argument against replacing the slant with a sb, especially the 360. hairline cracks in the heads, so they usually don't pose a problem. finding a good running sb that's not woreout? then ya drop in the small block, get rid of the 2 barrel intake, then ya buy a new edelbrock 4 bbl, or worse yet put a holley on there, than take out bank loan to buy gas for it!!???? than replace the rear end? torsion bars maybe?? exhaust.... so ya found a truck sb, now ya gotta change the pan.... then y want better exh man.....then ya got to buy decal stripe spelling out ya got a 318!!????? so did this make post # 180!??? unreal!
 
Why run anything other than what came in the car? Why run a slant? Why run a 318? Why only 383? Why stuff a 440? Why shoehorn a hemi? Why keep it stock? Why resto-mod? Why pro street?

Be cause we want to.

So, why do we want to?

I'll tell you why ~I~ want to...

I want to run a slant six because I am tired of V8s. I have had a lifetime of hot rodding V8s, and have never done a six... it's a matter of curiosity...

There are other reasons, too, but that's the main one.

I have learned that in order to get the kind of performance out of a slant six I want, it's going to need some help in the breathing department, so forced induction is in order. A friend of mine gave me and my racing partner, a new Turbonetics 66mm turbo. an intercooler and a waste gate, so I guess it'll be a turbo.

We chose to build a clone of two other engines I learned about on this site, Ryan Peterson's and Tom Wolfe's, because they are just about the optimum engines of this kind; the most HP for the least amount of money.

Neither of their engines have any exotic components. They both utilize flat-tappet cams, stock push-rods and rocker arms and cheap, easy-to obtain valve springs. No fuel injection; just one 4bbl carb on a 4bbl manifold, and a homemade header. Stock-type distributor hooked to an msd box...

They do both have 198-length (long, 7") rods and forged pistons.

That's about as exotic as it gets...

They each make about 500 horsepower.


I am not at all sure that you could build a 360 to make that much power for the same money.

So, when we take the car to a show, It will not be just one more small-block powered A body... in a sea of them. The same at the drag strip. where it just might do well. We really hope we can make power somewhere in the neighborhood of the output of Ryan's and Tom's engines, but that is a lot easier to say than it is to do.... We'll see...:prayer::prayer::prayer:

It is not a street car, so I am not concerned about gas mileage, but it should do well on that score because the cam is mild... and should have a smooth idle and good driveability because of its short duration.

The slant six is an unusually strong engine, so reliability should be good.

In fact, I can't see much of a reason NOT to build a /6... Just don't forget to include the hairdryer, so it will be healthy... and, FUN!

And so it goes.........it never ends once you start a project.

The 6 is going to the scraper, not worth the drive to the scrap yard much less MO.
 
Hey, I'm a fan of the Poly head 318 too ! Just sumpun different......
 
The May 2014 Automobile magazine has an article comparing the latest BMW sporty M3 sedan with earlier ones. They rave about the new 2015 "F80", a 3.0 L twin-turbo straight six which outperforms the clunkier 4.0 L V-8 and gets much better mileage. BMW drivers have always loved the straight six and the turbo makes it fabulous. We don't have to pay $63,000 to own one, just upgrade a neglected Mopar slant. For those metric-challenged, our 225 engines are 3.7 L and a 273 is 4.5 L, so who needs more displacement?

Look at the early Nissan Skylines with the twin turbo sixes....went like stink.
 
we will have to go visit FBBO if we want to get into the poly discussion!?? LOL I too think they are interesting, have a lot of potential, ( Ok so they are HEAVY!)
since you mentioned the staright 6, my girlfriend has one in like a 2001 jeep ckerokee 2WD. . she has no idea what mileage it gets or can't figure it!?? is that a good motor? or what? just wondering.... mail me direct, not trying to change the subject....
God bless slant motor, apple pie, and moon pie....
 
While I'm not the one who started the count, I see the responses are now over 160! That alone should answer the question, "Why the /6". :cheese:


Hmmmmm, 32,746 members and a 160 responses...not all pro /6...many by the same people...

Not even a blip on the interest scale...
 
very true "grassy". a mere percentage of A body owners for sure. but,,,,, slant people are typical "mopar" and enthusiastic toward their subject.not a bad thing..... I imagine most of the slant people that have been in the hobby awhile have owned their share of v8 mopars, and have plenty hands on experience and knowledge with them. I have. we might be interested in the slant to varying degrees, for many different reasons,,, but I for one, love the potential, of say, for example, a low compression 440 (read CHEAP!), that can be dropped in a light A body, just as I am intrigued by the guy that has studied a little more modern approach and got a turbo doing fun things with the lowly little slant.!???? how about the FABO member week ago at local mopar day at the local strip runnin 11.04,in his lime toad,,,,with his slant, well lets face it, give credit where its due. to me, interesting.
making good power, having a fun ride, being able to do this affordably, probably the backbone of the typical A body hobbiest!????? whether using a slant, s b, or B/RB motor??
yea I cruise the FBBO site some, had more than a few, like to have another..... great site, but hits on here vs. there.....seems to me, lot more activity here.... not taking anything away from those guys.....
and alot of slant people have given their reasons for liking the thing.........not trying to sell the sb or big block crowd,on it, maybe just adding information for some to consider.....especially the "new member " that has a slant A body that he's trying to decide whether to work on the slant or change it out!???? just me....

I don't know. I thought that 160 responses was pretty good (it actually says 192 responses when I looked). This thread has also had 4930 views. I would think that a lot of formerly disinterested in slant folks (like myself) have reached a new level of respect for the 6 banger after reading some of the posts. I'd even go so far as to guess that a few guys will be building slants now that wouldn't have before reading this thread.
 
I think the reason people like the slant, is why they like Mopar. There's a billion fords and chevys out there. Likewise, there's a million v8s. Dare to be different in a mopar? How about a mopar slant six?

If I wanted just power, I'd go to a v8. If I wanted easily recognizable, I'd go with Ford or Chevy.

But I pull up some place, and people are like "is that a nova? what is it?" They don't know it's a valiant. Then I pop the hood, and they see the strangest looking little engine, and a clean and easily accessible engine bay. Love it.

Not even a blip on the interest scale...

The trouble with slant sixes as regards "not even a blip on the interest scale" is that, due to their long-time history of being a non-performer, the great bulk of people reading this forum have a very strong. preconceived notion that from a performance perspective, slant sixes are a waste of time, and uninteresting because they JUST DON'T RUN!
There's a reason for that. The only cylinder head available for the slant six motor was originally designed for the little 170, and has very poor breathing when used on the 225. It's the only game in town, so-to-speak... nothing else has ever been developed for that motor... nothing.

So, we have seen a lifetime of normally-aspirated slant sixes that just don't respond very well to normal hot rodding methods of getting more power, at least, not in the traditional sense. In the general conception of hot rodding as regards slant sixes, the notion exists that, because they have never seen evidence that a slant-powered car, built right (with forced induction,) then it follows that a true "performance' slant six must not exist.

So, understandably, these folks don't bother to look any further.

The fact is, really fast slant-powered vehicles are so scarce that you really can't blame people for thinking what they do, but I think that the scarcity issue is going to change, soon.

I am sure that most of these "non-believers" are unaware of several pertinent facts about force-fed slant sixes. Facts like: Tom Wolfe's and Ryan Peterson's A-Body cars have engines that produce over 500 horsepower. Yeah, Slant Sixes.

Those engines make their horsepower UNDER 5,500 rpm, with no exotic components on board; no roller-tappet cams, no roller rockers, no exotic ignition systems, no dry sumps, home-made exhaust headers, no fuel injection.... only one 4bbl carb... and they do it on gasoline.

Ryan's '66 Valiant (with a 2.76:1 ring gear and pinion) has run 10.74 @ 127mph, with a power-sapping 727 T-Flite in the mix. With a lighter, more-efficient 904 transmission, it would probably have gone 130 on that run...

It weighs about 2,800 pounds with no driver.

Tom's car is a later Dart (a 1970 hardtop) and is heavier at about 3,300 pounds. It ran 11-flat and 122mph into a 15-mph headwind the last time out.

It takes about 500 horsepower to do that...

Both of those engines have a .065"-overbore, making them 234 cubic inches, each.. That's virtually 2.14 horsepower per cubic inch.

If your 440 made that kind of power, it would have 942 horsepower.

Of course, you can get more power (a LOT more) out of virtually ANY V8 by resorting to forced induction.... but the little slant six is built (by the factory) SO rugged and SO strong, that it is possible to utilize boost levels that would blow the crank right out onto the ground of those V8s, if they tried the high boost levels that Ryan and Tom have utilized in their motors. They both have run boost numbers in the high 20s... with no apparent damage. Try that with a 360 Magnum... I don't think you'll be happy with the results.

I have never driven (nor, ridden in) a car that would run 130 in the quarter, I'd imagine that most people have not. Ryan's car is fast enough to scare the bejesus out of me; my car (a 1972 Valiant) is a supercharged 360 Magnum that has low 11-second capability (118mph) and on the street, it is scary to me... That's 0-60 in 3 seconds...

I'm sure that it would feel like a sled to some of you, but to MOST people, it would get their attention. And Ryan's slant six car will run off and hide from my car!

At least, it runs well-enough to "Create a blip on the interest scale..."

When he word gets out about the true potential of the turbo slant six motors, I think it will result in a LOT of them being built... but, the word has to get out first...:violent1:
 
Leaning tower of power,Six on the side,Six on the slope,and my favorite,The Detriot Lean.
 
This topic is interesting.

I think there is real confusion between power and comfort. To give a bike analogy, The RD500 and perhaps the RD350 were faster than my CB900F super sport. I tried not to tangle with those (but I liked eating KZ900s :>) but, and here is the big BUT...on a long trip, my big 4 would be loping along and on the RD, after an hour the rider's body would be numb. They were not long distance bike..more burger store warriors.

The v8's tend to have heavier and smoother suspensions..drive a v6 stang and then a v8 stang (2005-09) ..the 8 is a lot more comfortable.

I really don't care how much hp the v8 will make nor the 1/2 mile speed since this car will never be in those situations..

Regardless, in a previous post I mentioned that I will now look at the /6 in a different light..but I still want a V8 :)
