    Dave's hemi

    Like gunswanted, I to came across an Edelbrock ds495 intake manifold. Other than mine and his it's still the only manifolds I've seen. I'm not big on the desoto hemis, mostly focus on the Chrysler engines so I thought I'd let you guys know I put it up on eBay for anyone searching for one. (Not as good of shape as gunswanted manifold but will polish up nicely

    I know this is an old thread but I am looking a 3x2 or 4x2 intake source. I can't afford the high dollar vintage Horne and similar intakes so who is making the tube manifolds and/or u-fab kits? Again only looking for 3x2 or 4x2 for a Chrysler hemi.
     
  3. Gear drive speed has a 6x2 log cast in aluminum. There are kits for steel u fab intakes on ebay for around 125. There was some one building the u fab intakes a few years ago, but I cant recall who.

    received_1005388449849792.jpeg received_1991660177610069.jpeg received_10208849921140454.jpeg Hi, Folks... I thought I was in the home stretch on my hemi-powered project, a 1965 Dodge D100 with a 1958 392 Hemi & Tremec 5 speed.

    We got too clever, I guess. We took the drivetrain out and I traded off the Sid's dropped axle & disc brake setup. Then we went ahead and installed a Crown Vic front end.

    All the welding is done and when we went to drop the drivetrain back in... my prized 4-bolt manifolds crash into the original engine mount on the CV frame. I posted a pic where you can see the manifold flange just a little ways above the stand for the engine mount on the CV crossmember.

    I checked the Hot Heads site... they have a nice diagram showing how all of the headers they offer would absolutely not work. I am faced with either fabbing up a set of headers or... trying to find some kind of "rear dump" OEM manifolds. If the collector were moved back a bit, everything would be fine.

    I contacted Sanderson who made a beautiful set of manifolds for my 270 Dodge poly (hand-crafted engine by none other than 73RR). They can't move the collector back unless I send them my truck and (cough) $1500.

    So, anybody have any ideas?

  5. In the big scheme of things 1500 for custom headers isn't bad and Sanderson in California isn't the only ones who'd do it, I'd do it for you in Ohio. I'd bet there's a few someone's in Detroit as well.

    Now you'll be into modifications someplace to get this done.
    Cut out or notch the offending CV parts.
    Modify a set of headers from a BBC, LS, or Ford
    Modifying your plan and Change the front end to suit the hemi or change the hemi to an engine that suits the front end and both of those seem way to drastic if just 1500 gets you out of the jam.

    I'd have to look at it the whole thing but my gut tells me hack the offending CV stuff out of the way would be the best way as that is the problem. Exhaust that doesn't fit is the symptom, but without looking or being familiar with the CV setup modify or custom make the exhaust might be easier
     
  6. Something to think about
    Modify or build your own

    Very primitive but Something like these could be turned around with a turndown collector
    Make them nicer if you want

    Jon, very interesting dilemma and I'll expand on our PM.
    As said, I'd look hard at the CV parts and see how much whittling could be done in order to clear a 3" pipe.
    Also, as mentioned, we have in years past, used brand 'x' headers that fit the chassis and welded on Hemi flanges to suit the build. This can be a bit time consuming but well within reason, dollar wise. The biggest issue will be with the flange angle on the Hemi compared to all other engines.
    This is a Gibson header, no idea what the application is (flange looks like bbc)(stole the pic off the web) but the basic design looks promising. No doubt someone there could ID the part.

  8. That's an ls manifold pattern holes on center
    BBC hole pattern is high low high

    ....it could be just about anything in my world...just not EarlyHemi...:p just thought the design could offer something of value.

    We ordered LS manifolds & Hemi flanges from Patriot because they have a "tight tuck" piece which has rear dump & is tight to the engine. Here is a pic of a hemi exhaust gasket laid over the LS manifold received_1858673194237688.jpeg

  11. Maybe a marine exhaust of some sort can be modified?

    I would love to run something like that but from my understanding, they have to be cooled... they are used to being cooled by lake water!

    Industrial ones look similar.
     
  14. Little pushing after the cutting and you’ll be good.

    I made oval transitions to round to take advantage of the large ports and funnel into round primary tubes.

    Wow.
    So... shiverlay parts do have some value...;) The angle to the head should be easy to address.

    Well....we keep trying. This set from Patriot hits the starter. I basically need a block hugger with offset collector. Pics show yellow box where collector needs to be. Last pic shows the optimal space where headers would fit. @31Vicky...if your shop were closer....vehicle is in TN right now. received_427255071376636.jpeg received_2135956783153680.jpeg

  17. I can’t really move it lol

    The standard issue block huggers won’t work?
     
  18. The 4 in a row layout gives room different than
    2 +2
    And there’s a little different things in all of them 558890C0-1D69-40C6-8AB9-D276DF58C609.png CABE0B4B-CB13-441E-851E-E0AA55D00630.png
