I know that the "Mopar Muscle" magazine said they would NEVER do a slant challenge, but am I the only one who is sick of the last few? I think it would be interesting to see what these builders could come up with.
How about it, should we pepper their inbox with requests, or am I the only one keen on this?
 
I don't have a /6 car. But I think it would still be interesting to see what kind of power they could get out of one.
 
Half the reason I canceled my subscription was because of the stupid engine challenge in every issue. I won't re-up my subscription but I would buy it off the new stand if they had one or two issues with slants in them.
 
They claim that sixes aren't muscle motors...fair enough, I guess. So maybe they should show us how to make them muscle.
 
Ya,we could never compete with those stroked 440s,,,,wish I knew how to put my video on this thread.Guzzi Mark
 
Randy Bolig couldn't find his butt in the dark with both hands.
 
I don't know why they even do them. They never tell you the cam specs or much about them at all. Who wants to know how to make a dyno challenge motor any way. Thing was made to run a few times with the cheepest parts they can and every trick in the book to ring every last HP out of them. May be good for a dyno motor but I hop no one trys to copy them.
 
"I'm thinkin' the 440 RoadRunner should take the win..."

RRRRROOOOOOAAAAAAAARRRRR!

"...the RoadRunner trying to close in...!"

Anybody got a video of a N/A 318 doing that?
 
Randy had to fight the "Powers that be" a few years ago when they did the Slant with Mopar Engines West. They said "Who cares" and were worried about sales on the stands.
At a show he told me they had more responces and e-mails and sales were up for that month. I know we are small but mighty. AND the participents in the challange builds want to sell the product and engines when they are done. Anybody want to pay $14,000 for a Slant ? $12? 10? $5 ? I am just saying and in no way do I want to piss anybody off but we live in a world that Corporations only think about the bottom line. We are lucky that we have any "Mopar" magazines. Look what happened to "Mopar Enthusiast"

well in all fairness to that mag it was combined with the ford and chevy one to...

as far as SL6 in the mopar mags... they come right out and say that they are not worth the article space... but it would be awesome if they did...
 
I plan on going to the inlners race in Phoniex on march 27th.My goal is sub 11.40s.Pretty sure i can do it,then again I have over 250 runs on my combo and will need anouther 30 or so to get me where I think I need too bee.If I show I am willing to bet.Guzzi Mark
 
I think it would be a true test of engine builders' abilities. They go off score, not just the most HP. If the HP to CI ratio is good, then the points are high. Don't remember all the parameters the points are based on.

i live here and didn't even know about it! plz tell me its at speed world and not firebird...
 
Seems to me that the motor challenges are about the builders and not about the engines. Since probably 97% of the readers could car less about how much power can be wrung out of a /6, I see why the magazines aren't trampling over themselves to devote the resources to it.

IMHO, any competition that does not include a comparative index of fuel consumption and durability doesn't do justice to the things that make the /6 a great engine. The engine got it's deserved reputation by being reliable and economical to operate. Besides, if the /6 were to become mainstream, look for supplies of parts to go the way of the E-body and shoot into the stratosphere.

Not really sure what you are trying to say :read2:
I just thought it might actually make for an interesting shootout......for a change. If they did it, I would buy the rag....and hell, I already by Amsoil(I have to, my mom sells it)
 
well who has the fastest 1/4 mile slant ?
how much was that motor built for?
that would say a lot.

you do know there arnt many hp slant six products to sell, thats one reason there are no builds..no advertizing in a magazine..there's mopar V6 builds... even the neon 4 cylinder build holds records..

571 crank HP using Wallace HP calc. Stock bore old trw forged pistons, used rings, self hone on used swather block without any bottom end work. Self port head and used parts. Cam and valves were new, basically bolt on HP parts but I'm sure they wouldn't do a build-off with power adders...but would they? Later

You can stick the six you know where. I buy Mopar Muscle because i like to read his article every month. I don't care about the engine challenge much. Hunky
 
He does an article? Oh, is that the page where he talks about his dining room, or his wife getting mad at him? I think that rag is going to go in the toilet....very soon, I'm afraid.

The problem is multi-faceted....

A year ago, I couldn't even spell "slant six"... but I got on the Slant six.org website and this one, and began reading, and learned a few things. That's pretty amazing in itself, 'cause I'm what they charitably call a "slow learner.":read2: Sometimes, a lot worse,,,:angry7:

Be aware that my personal "hobby" car is a 1972 Valiant with a 360 Magnum V8 equipped with a Vortech V-1, S-Trim, serpentine belt-driven centrifugal supercharger that makes about 525 flywheel horsepower. Not that THAT is any great shakes ('cause it's not, I realize) but it does give you a clue that I have not been a "slant six guy" from day one.

As I immersed myself in the postings about /6 performance, and videos on You Tube of various /6-powered cars, I began to realize some things about these slanted little devils that had escaped me for years. Here's are some things I had missed.

In a general way of looking at the /6 archetecture, it says one thing in a big way: This cylinder head may be a perfect head for a 170 cubic inch engine, but trying to make a normally-aspirated 225 breathe through those same 170-sized ports is a job for Superman.

What I mean by that is, the ports and valves, as manufactured, are just too small for the amount of cylinder displacement they are asked to feed, in a high-performance 225 environment.

The /6 has 225 cubic inches, If it were a /8 it would be 300 cubic inches with 8 of the 225's (37.5 cid) cylinders instead of 6.

Just for comparison purposes to show what size these ports and valves are, the 1967 Chevy Z28 came with 302 cubic inches (virtually the same size cylinders as a 225 /6 engine,) and their intake valves were 2.02" in diameter (slant six "oversize racing valves" are 1.75, or fifteen percent smaller than the "stock" Chevy valves, and the 1.6" Chevy stock exhaust valves are still 6-percent larger than the "oversize racing" /6, 1.5" exhaust valves.

The Z-28 Chevy ports in the head are commensurately larger, so that the flow numbers are a pretty good match for the valves, in their stock configuration.

The bottom line is, a mildly ported (302) Chevy intake port will flow close to 300cfm to feed the same size cylinder that the /6 is trying to fill with that 1.75" valve that is in a head, that after porting, will flow 220cfm, absolute max...

A big, heavy crankshaft doesn't help matters, especially when winding up 1st gear.

So, here's what I have learned:

I watched videos of the chopped, 2,350-pound MadMax 1st generation Valiant with a normally-aspirated /6 running 11.50s with NO power adder of any kind.

That car is incredibly fast and quick (watch how it hooks!!!)
I've never seen anything like it!
I didn't REALIZE that a normally-aspirated Valiant or Dart could run like that!

I happened onto two more videos on You Tube that opened my eyes even further.

There were two videos of turbocharged 225's that blew my mind. Tom Wolfe has a 3,300-pound '70 Dart that has run 11.02 with a new motor (at 122 mph), into a 15-mph headwind, while another forced induction racer (turbo66Valiant) posted videos that showed his pristine '66 Valiant running some 10.50's, which is about a full second quicker than the already fast, but unblown, Mad Max car.
Not to belittle the Mad Max car, because it's stupid fast for its combination, but that '66 Valiant is I believe, 500 pounds heaver and a full second quicker. And, its running a 727... probably about .2 slower than a 904.

So, what did I learn from all this???

Not so fast; I said I was a slow learner, and I surely am...

I did a lot of research about the /6 motor, and one thing stood out:

It's built like a brick pagoda. Its aluminum ancestry seems to have left it with an infrastructure that has no equal in the modern automotive world, when it comes to strength and ridigidity.

Remember that big, heavy, crankshaft I was carping about awhile back?

Well, I found that the early models are forged, have internal balance, and bearings the size of the 426 Hemi.

As close to an unbreakable stock crank as you can probably find.

The cylinder walls can be bored over .100", the head can be milled that much if need be, and the top of the block is pretty thick, but I have no reliable numbers for that.

What all this means is, unlike the Buick GN turbo motors which (the stock stuff) don't seem to want to stay together if the boost goes much over 25-pounds, it's an open question as to just how much boost one of these /6 motors could stand, if someone greally got serious, because K-1 is making some great-looking forged rods for a 225, and forged pistons are available from Wiseco in a .065"-overbore, creating a 234 cubic inch motor.

Shaker223 and turbo66valiant are probably generating over 500 flywheel hp as we speak, but can 600 hp be far behind?

It's not necesssary to build a 500hp motor to have fun with a turbocharged /6.

One of Tom's early engines was pretty much stock with a Buick turbo stuck on the bottom of a stock exhaust manifold, and it went high 12's...

The possibilities are endless!:cheers:

I'd think twice before pulling that /6 out of ANY A-Body....
Might be shooting yourself in the foot...
