    Slant/6

     



    Hi, I'm new to the Forum, but not to old cars. My problem is, I'd like a dual 2bbl carb intake for a mopar 225cu.in. I've had a 360/auto and would prefer something everybody else doesn't have. Anybody know where I need to look? Thanks, Robert

    I sure do know where to get a 225 slant six i used to have one my self . A 77 plymouth volare had them or the 75-77 dodge aspens had them . Most of the dodges from 73-77 that wernt a muscle typ car or may have had engine options had them .

    In very rare cases there were aluminum block 225 slant sixs . Mine had a 4 bbl intake nitrous the head was re worked and was kinda cool . They only have 110 horses but can be made to put out 300 if worked over properly

    Try the internet for clifford performance they make all kinds of stuff for the slant six

    Robert,

    Do I understand that you want to put two two-barrel carburetors on your engine? I'm not aware of a manifold like that, but /6 intakes for two single barrels were made at one time. Even J.C. Whitney offered them. If that interests you, ask around. Somebody may have one laying under the workbench and occasionally wondering "what should I do with that?"

    Take a look at the "Mopar Chat" website <http://www.moparchat.com/forums/search.php?searchid=95992>. They have a slant six forum and also a parts for sale section.

    If you're thinking of a single two-barrel to replace the one-barrel you have, Jason is right. Factory two barrel manifolds were produced for your engine and should be available, but you might have to do some sniffing around to find one.

    Converting your present intake to accept a two-barrel is a simple modification. I did a couple myself. If you are interested in going that route, send me a PM with a mailing address and I'll send you some instructions and a picture or two of one of them.

    Also, you might take a look at a thread started by "joker51" early this year, <http://www.clubhotrod.com/forums/showthread.php?t=22461> There is some pretty detailed slant six information there.

    Thanks to all for the info. My Duster already has 225 +.030, 318 valves, 340 springs, block cut .060 and '76 2bbl intake and exhaust. I've seen the 4bbl setup sold by Clifford and may end up with one, but one of the old mags had a twin 2bbl setup shown. Don't remember performance data, loved the looks! Can't find perf. info on hyperpak intake, like the looks from a perf standpoint. Started out with original 340 car in the '70's, bought this one to play with. Had 6, changed to 360; handles better with my stiff suspension with a 6.

    I know what you mean about a manifold that Had twin 2 barrels. I had one 40 years ago for my 56 chevy 235 but I can't rember who made it. Hell I can't rember things from yesterday. I know I had twin 97's on it and it ran pretty good.
    Keep smiling, it only hurts when you think it does!

    And ya got lots of room for a turbo in a 225 engine bay, might be a fun project, I remember a inline six 68' stang running a junkyard turbo setup that dusted alot of small blocks, sorry no detailed info, this is going back to the mid 70's, turbos were'nt real popular and you could tell quick by looking that it was a backyard setup, but it would run.

    wouldnt a small blower work petty good on a 6 banger as they are already a long stroke motor and not a real high spinner?
    shure would get things happening re tourque and hp asap

    just like the Fords, Mopar had cars and engines made in australlia, and the parts are far superior to what we have here, rare here in america to find, and somewhat rare over there, is slant 6 HEMI heads, or the stock 250 2v ( Ford ) head from Oz is considered a high performance add on in america because they have a removable intake ( all American heads have an integral intake ) that accepts a 2bbl carb, and flow much better. there is an Aussie 225 / 6 that is dynoed over 600 Hp, turbocharged, no NOS. Turbo's are becoming popular for the Mopar and Ford 6's. my '67 200 will get turbocharged when I get the parts for the turbo I have.

    not really, a turbo will make more Hp in such a small displacement. on average it takes 32 Hp to run a blower, it takes almost none to spool up a turbo. on a small displacement, the extra air volume from the blower wouldn't bennifit, on a V8 it would.

    Robert -

    Some Chrysler-provided poop I have says that three Weber carburetors (48 IDA) will "improve engine output nicely" compared to a Hyper Pack inlet manifold and carburetor on the slant six. The sticker is that a hand fabricated inlet manifold would be required (one cylinder per Weber throttle bore).

    A far less expensive way to go would be to modify a standard intake manifold to accept a four-barrel carburetor that was used on '65 and later high performance 273's, that carburetor being a Carter 3854-S.

    If you're interested going that route, Chrysler says:

    1. Replace the metering rods with No. 16-177 rods (.067 - .065 - .055" dia.)

    2. Replace the throttle side seccondary jets with No. 120-181 jets. (.049" dia.)

    3. Replace the choke side secondary jets No. 120-226 jets. (.065" dia')

    4. Replace the primary venturi clusters with cluster No.448-264S.

    I have not tried converting a stock manifold to accommodate a four barrel but it has been done and it shouldn't be too tough. Converting for a two-barrel is a snap, but rigging for a four barrel would be a little more involved. You'll have to make a 1/4" steel plate shaped like the gasket for the carburetor and weld it (or in my case get a REAL welder to weld it) to the manifold. Just be careful to center the four barrel bores on the standard plenum chamber.

    Let us know what you decide to do and how it works!

    Jim

    I had a '76 Volare wagon with a four speed and read up on them. I recall an article in Hot Rod in the '80s about adapting a turbo from one of the aluminum Olds-Pontiac-Buick aluminum 215s and the guy running it was winning his class with the turboed /6, which is supposed to have a stout bottom end. If you can find one of those old aluminum v8s with the turbo the match seems to be good with the turbo set up for a displacement a little smaller than the engine size so it will rev up fast. However, it may be easier to find a turbo from one of the Ford 2300 (122 cu in) engines, although that is not necessarily a good match for overall displacement. Mainly what I am saying is that if you adapt a turbo from another engine it would be a good idea to find one from an engine with a displacement a little smaller than the 225 size rather than larger. If the turbo is from a larger engine there will be a lot of "lag" and maybe you will never generate enough exhaust gas to rev the turbo.
