Does anyone know if they make headers or if you can even put headers on a 225 slant six?
I am buying a 70 Dodge Dart tomorrow and want to switch out to headers if possible, I will be driving this car as a daily driver as it is in too good of shape to just part it out for the 49 plymouth. I will continue the look for a new engine for the plymouth.
Will post pics of the car when I get it tomorrow if anyone is interested.
Tim -
Some time back in my "Dad and son projects" posting I mentioned that I had some stuff provided by Chrysler entitled "Slant Six Performance Tips". There is good information in there for anybody who is interested in getting more power out of these engines.
If you'll send me a PM with a FAX number I'll get a copy to you if you want one.
If you decide to make your own headers it will tell you what you need to know in the way of tube sizes, tube lengths, etc. as well as some very inexpensive modifications you can make, such as how much you can mill the head and how to adapt a two barrel carburetor to your stock intake.
These are tough little engines. I have use several of them in cars and trucks, and even one in a houseboat.
As I said, let me know if you want the information.
Jim
There was a Hyper-pak S-S with factory header and a small AFB in the '60's. I drove one (a rental) and thought it was a 318.
Check out back issues of Hot Rod, or Popular Hotrodding.as they had an article on a day at the track,where a guy showed up with a slant six a surprised quite a few. Hope this helps, Hank
You can also check out the for sale posts on this site.......

FYI........ Be careful with Clifford...... there have been some complaints about their service lately

If you can check through back issues of Hot Rod in your local library microfilm holdings you should find some articles about the XR6 built by Tex Smith, I believe it won AMBR but I forget the year. There is in Hot Rod somewhere back in the early '80s an article on fitting a turbocharger from one of the small 215 Buick-Pontiac-Olds aluminum V8s to a 225 along with 1/4 mile test times before and after and how to modify the 215 turbo with an adjustable waste gate controlled by a knob on the dash board. I had plans for my 225 Volare with 4-speed stick overdrive and I bought such a 215 turbo but lost it in the midst of moving from one house to another. Maybe a turbo from one of the modern 4-cyl engines could be adapted to a 225. The idea is that the 225 has a pretty stout bottom end and can be turbocharged without worry, but the key was that the turbo for the 215-V8 was matched in size pretty close to the 225 displacement and had a waste gate that is easily adjustable.

There are guys on the site above that have used late model turbos on the /6Quote:

Myself I used a Rayjay turbo on mine........
Also not all the 225 have the same bottom end........ not sure what year but sometime in the 70's they went to a cast crank

Thanks for the info guys I will look at all the options.
Bigtrack, sorry I don't have a fax.
Some serious Mopar sixes -
The first two pictures are of a "slant six" powered dragster built by Jim Nelson and Dode Martin of Carlsbad, Califonia, the "Dragmaster" and "Dragliner" boys.
The third and fourth pictures are of a really remarkable "G Gas" coupe built and raced by a guy named Pete McNichols from Hazel Park, Michigan. The car is an original (steel body) Willys coupe, and the engine is ..... get this! ..... an early 170 cubic incher, not a 225 c.i. later one. The 225 was the "big" engine!
Don Shillady speaks of Tex Smith's "XR6" roadster. Now, there was a true work of art. Sorry Don. I couldn't find a picture of that one.
Jim
Naturally I screwed up, trying to send pictures. That one is Pete McNicholls' engine. I'll try to send a shot of Pete's coupe now, followed by the Nelson and Martin car. Wish me luck!
OK, don't yell at me! That's Nelson and Martin's engine. Now I'll try Pete's car again.
Now. Nelson and Martin.
Some day I'm gonna be forced to admit that this photo transmitting business just ain't my thing.
Hey guys,
I also just bought a slant 6 225. My plan is to turbo it and do custom exhaust. There was a set of headers on ebay a couple days back if used is the route you want to go. as for a turbo, do a google search for "turbo slant six" it'll give you a page for a guy who did a turbo setup for under $400. I'm using his info to make a custom setup for myself. keep us updated on your progress.

The newer light engines have the cast crank with fewer counterweights, and a lighter head with no spark plug wells. The older stuff is much better.
This one has t he wells for the spark plugs with what looks like inserts.
But the car is on hold right now, someone beat me over there with $50 to hold it. I was going to pay all up front, but couldn't get a hold of him as his phone was dead all day, and when I finally got over there to talk to him I was 45 min late. He said the guy was going to pick up the car tues or wed, and if he didn't or backed out he was going to call me so I can come get it.
If I don't I can always pick up an old rambler for $200. The car is a little rusted out but I can still salvage parts off of it.
Looks like this one only worse

or this one. I do know its a rambler classic just not the year. but these 2 are close

Ok found a new engine, Ok not new but anyways. Does anyone have any pics, close ups. of the motor mounts of a slant 6 225? I am looking for how they are mounted, and a general location of where. This engine is out of a 76 aspen.
Also where can I get some mounts? Both for the engine and the frame?
Thanks for all the help you guys are great.
Tim -
Here (maybe) are some pictures from Chilton manual of slant six engine mounts. I hope you can tell something about them.
Jim
That seems to have gone somewhere, so ....
One more time.
Incidentally, the offer still stands.
Jim
Say, kustom_oz, please check your PM's when you get a minute.

Say, Joker -
It seems to me that some time back you said that you intend to use an automatic behind your Mopar slant six. This morning I was scratching around in that big pile of crap I call "my files" and found another Chrysler publication entitled "Modifying the Torqueflite for Special Applications".
I'm in no way a transmission man so I don't understand a word of it.
The smaller torqueflite was known as the "A904" and was used with the slant six starting in 1960 and with the 273 V8 starting with the '64 model. The two engines had different bolt patterns, so if you haven't bought a transmission yet and you find an A904 behind a 273, don't buy it. It won't fit your engine.
If you want a copy of this information, lemme know and I'll send you one. Then you'll owe me TWO beers.
Oh .... and Don Shillady, if you see this, I did find a picture of the Tex Smith "XR6" slant six powered roadster. It's on the cover of a booklet on bodywork and is sort of doggy looking, but I'll post it when I get a chance.
Jim
Big Tracks, scan and post the picture of the XR-6 mainly for the younger folks to see a very innovative roadster powered by a slant six. I took a trip to the Midwest a few years ago and part of the trip was an adventure in a little 6-passenger plane where I sat next to a Dodge/Plymouth dealership owner at a time when I had a Volare wagon with a 4-speed OD. He told me that many of the slant six engines would go well over 200,000 miles without even removing the head for any service, they are sturdy engines.

You're right, Don. They're really good engines. You probably figured out that I'm a fan of the slant sixes by my postings in this thread!
I have had two slant sixes with over 160,000 miles on them and the only real problem I had (with both of them) was worn out valve guides.
Jim
Okay, Mr. Shillady,
Here, unless I messed up (again), is the Tex Smith XR6 roadster. The booklet I took the picture from is probably 1963 vintage.
It was unique not only for its engine but for its assymetrical body body design.
I'd say the picture speaks for itself.
In case that front suspension looks like early Volkswagen, it's because that's what it is!
Jim
nice to see some slantsix talk, i have been racing and street drive slantsixs for years, headers and after market 4bbl intake with 600cfm vac secondaries makes a nice comb for street but if you cant find header or you dont want to make them doug dutra in ca. makes dual cast iron ex manifolds check them out on slantsix web site.slantsix best engine ever built.:D
as for a transmission go with 904 but get a 318 904 from 1985 to 1993 ,for parts,they are lockup trans but they have the low gear set you can put all the sun gears and high clutch drum in the non lockup trans. that will give you 2.74 low 1.74second and 1to1 high, also you get the five disc front clutches,this really goes nice with low end tork the a slantsix already has.:D
You listenin' to this, Tim?
Jim
I had a 74 dart with a 225 for a while... that car wasn't too fast off the line, but once you got it goin, it hauled azz. I couldn't hurt that thing if I tried
I'm listening, and I am taking notes. I plan to make a grewat 225 out of this. I am thinking of staying with the slant 6 in the future also, No need to redo the steering just to fit a V8 if the slant six will give me a good top end.
One more question, I got the tranny from the 76 aspen also. How do I tell which tranny it is? I haven't dealt with trannies in 18 years since I was in High School auto mech.
Hard to say for sure which one you have, Tim,
My Haynes manual says the A-904 is the most common one used with the sixes and that's probably the one you have. It says that there is a variant known as the A-904LA, and this may be the one with the lock-up converter Terry talks about. The book says that "many 1978 and later" transmissions were equipped with the lock-up converter.
And something else I didn't know... some six cylinder cop-cars and taxis came with an A-727 in them. It isn't too likely that you have one of those, but it would be neat if you did!
Jim
LA is the designation for the small block V8 (like saying Windsor in Fordspeak), so the 904LA would be the V8 version.
This might help Tim; http://carcraft.com/newlook/crc_act/...ans/index.html
hi again,to tell the diference between a 904 and 727 with out having the to along side each other{727 is much bigger than a 904} is the shape of the base pan, on a 904 the pan is square with one corner cut at 45deg angle, on a 727 the pan is also square but under the dip stick the pan is push out is a round shape.but if you want a quick slantsix stick with the 904 it uses less hp to get moving, i have drag with both and everthing being equal the 904 is 2tenth faster:D
Ok rather than starting a new thread, I figured I would resurrect this one as this question deals with this engine.
Ok what size electric fan should I use with this engine? I am looking at electric as I don't think there will be room for a pump the pulley and a fan between the rad and the slant 6.
What cars would have the donor fan for me? And what all should I take off the donor to make it work?
Tim -
Something occurs to me. In the early sixties Chrysler produced some aluminum slant six blocks. No kidding. I once owned one but I wound up selling it prior to one of my many moves.
Finding one now would be a big challenge, but who knows? Some old clod like me may have picked up one years ago and it may still be over there under a pile of other interesting stuff.
As you would guess, they are (were?) a bunch lighter than their cast iron brothers. They (Chrysler) also made some stock aluminum one-barrel intakes. I actually still have one of those that I converted to accept a two barrel from a 318. (Sorry, it's not for sale).
I just thought I'd pass that by you. If you are interested you might try advertising and/or keeping your eyes open when you are wrecking yard scrounging. They're not too hard to identify.
