ok so just desided to keep my slant six insted of putting a v8 in my 1973 dart swinger. so my question is what should i do to it to give it more power? the car has the stock everything in it. its auto and i want to make it stick also so need know how to do that and what i will need? and how much power can i get out of a 225 ?

TVLynn

Keeping the 6.. wait on the rebuild Look for a late 70's 4sp overdrive, bell housing and related parts, 8 1/4 rear and new drive shaft... do that part first !!!!! Other wise the first time you dump the clutch the rear end is liable to come apart !!!

this site is THE site. http://www.slantsix.org/ first decide the intended use. 1. daily driver. 2. street racer. 3. FAST street racer. 4. full drag race. for a daily driver just dont over cam it, or over carb it. for a daily driver dont go much over 268 degree advertised duration, not .05. and. 430 lift. with a 2bbl carb off a 318. i built one long before chrysler did. be VERY sure it does not jam at wide open. and use steel tubing fore the fuel. do NOT use long lengths of hose.

In another post yesterday, I mentioned a guy that I met recently that had some hot slant sixes and engineered his own parts. A moment ago, I clicked the 'slantsix' link above, and that's the guy! Doug Dutra! Anyway, I have seen some of his slant six stuff around and he has a dual exhaust system that goes by "Dutra Duals" which start out as set of split set of exhaust manifolds that look very cool. I think that the manifolds are cast...
I heard one of his six's run and it sounded cool and other than what I have just written, I know very little about where to start with a six. Good luck!~

ok well i plan on driving it alot on my free time . i dont need a drag car but i want to be able to burn the tires if i wanted to .

i agree witj tvlynn. if u were here in ny i could point you in the direction for parts. get rid of that auto and get a good set of gears with a posi in it. mabey 3:55 gears. then build the engine thay way you jave a solid platform

This is a mid 1970's Cast Iron A-833 A833 Chrysler 4 Speed Overdrive Transmission. Main Case (C 99129), Tail housing (C132123), Side cover (C-99386) i found this for 1,400$ is that a good price or is that to much?

slade

i just found one in a junk yard lol

yep Doug Dutra is THE guy. be sure to pay attention to the bolting the ext manifold.

It's sounds a bit high, I have not tried to buy one. I have never bought anything from them, Brewers Performance offers a rebuilt 23 spline 4 sp for $1299 OR a Complete package for $4k. Look for a 5 speed setup from a Dakota.
Or

Goes back to what others have said Sell your Dart and Buy a V8 dart.. OR buy a V8 dart and swap the drive train into your Dart. Put the 6 into it and re sell it... Just expensive to change it.. ANY kind of 4 speed dart is going to cost $$$$$.

Another option Look around and find a Wrecked early 90's Dakota with a good drive train

slade

he wants to build the 6 bud

TVLynn

He ALSO wants to convert to a 4 speed !!! And keep the 6 only because of the cost to do a swap !!!

slade

your acting.like a chrysler 4 speed is hard to come by. and like a A body with a 4 spd is a big dollar car.
the guy could find a parts car that has a roached rear clip but has a v8 4 spd and buy the car for scrap weight.

slade

mabey its just because im in newyork and i see this **** all the time

mr340

A-body 4 speeds are not easy to find, they have a short tail as opposed to every other mopar on the planet using the long tail. If you can find someone parting out a Dart Lite (i think someone on the board mentioned one recently) get that trans, it has the aluminum case overdrive unit in it. the swap is not hard as long as you have everything you need, trans, floor hump, correct linkage and z-bar, pedal setup etc.I don't remember if the 904 driveshaft yoke will fit the 4 speed.

Welcome aboard and go to Clifford Performance for all your slant six performance needs.

slade

theres literally a 4sp for a slant6 laying in a junk pile in gabas junkyard 20 mins from my house.. i see a body 4spds all the time idk to diffrent parts of the country

4speed with granny gear SM465 and NP 208 transfer case passenger side drop with driv shafts. Sell together $250 or separate $150 each. Came out of 82 dodge
. ok thats what i found is that what i should get or is that wrong not sure exactly what i need to get im not the best at this.

78D200

Welcome!

I wouldn't get the SM465 unless you plan on yanking tree stumps with your Dart . The SM465 is designed for towing and hauling. Also, that guy probably has a NP435 as sm465 only came in GM trucks. Other manuals to stay away from are t4, t5, t14, t15, t18, t19, t90, t98, t176, sr4, sm420, np435. If you are not sure, just ask like you have been.

What about a manual out of a V6 Dakota? Late you can get a gen 2 version for cheap and the rear axles in them are 8.25. Only down side is that it would be a 6 lug and not 5 lug.

welcome to the forum

a 5 speed out of a 97-04 should be a nv3500.that woild be the best one to get. there in.rams also

moe7404

i had a 1964 dart 4 speed stock. very rare. i built a 318 2 bbl carb on the stock intake. that realy perked it up. be sure you mound the 2 bbl with the throttle shaft parallel to the crank. and do not weld the stock cast iron intake, it will warp the center ports. machine the the stock part flush. make a 1/4 plate to fit the 2 bbl carb. use counter sunk screws to hold the new plate. and double check that the throttle does NOT jam wide open. if it does and the engine overrevs it will knock out the pistons.

ok i looked up the 5 speed on the websit and 4 k doesnt sound to bad for everything it comes with. but do you think it be cheaper to just find 5speed out of a dakota and just. it seems easyer to me to just get the kit but i dont know never did this before.

1973dartswingerdms

"8 1/4 rearend with 2.76 gears big bolt pattern" I found this for 300 is this what I need or are the gears to low?

Silverick

An 8 1/4" with those 2.76 gears are considered "high" gears. They would technically work and be good for the freeway but, may be too "high" for your project.
An 8 3/4" rear end and a set of 3.23s or 3.55s may be a better selection.

slade

a 8:1/4 rear will be fine you can swap the gears later to somthing like a 3:55 a 8"3/4 for a a-body will bw hard to find and there a 800 dollar rear. 8:1/4 will do just fine.

the 5 speed from a 97-04 dakita will be the best there also hydrolic clutch and the nv3500 will handle power well

Ok i found a 5speed 1997 from a dakota. It had a 4 cylinder in it is that going be a problem? needs be cleaned up and probly rebuilt does it cost alot to rebuild?

A friend & I built his slant a body last year. It went 16.4 @ 89 mph. Don't worry about a 8 3/4 there far to heavy for a 6cyl. A open center 3.32 6cyl diff is fine it'll brake traction before it brakes. My mate got a full rebuild kit from flatlander racing & upgraded the can to the comp cams 440/400 lift solid cam. I did a mild port job & cleaned up the bowls after we cut the seats for the largest over size ss valves off eBay we could find. Decked the heads & block to. 9.5:1 compression , a set of headers & 2.5" exhaust & alloy 4bbl manifold with a 450cfm volley carb. It made 126 rwhp & over 400flbs of torque . he has a 904 with a std torque convertor. He was on a ultra tight budget . if anybody want more info I'll get all the specs.

According to a Chrysler Corp. Engineer on the Allpar website, the slant 6 had a higher volumetric efficiency than the 426 Hemi.
