    I posted in the parts wanted section too. I'm looking for a set of the adapter plates for the stage2/3 tall port heads to a Mopar 440 intake if anyone has a set. I'd rather buy than fab if they are available. Thanks.

    The Mark Dalquist with his 67 Riv pictured in The TA catalog. Back then u were at 11.66 @116mph. How much has ur combo changed and have u bettered that et?

    Here is the info..

    I took that adapter plate design and converted it to a weld on style. the bolt on stuff was a C/F, I did it years ago.

    With my design, you leave the mopar flange on around the ports, and remove the rest of it, and then weld the manifold to the adapters.. and then add a valley cover plate, into the notches in the adapter plates.

    Fab/weld up a sheetmetal water manifold, and your good to go. Folks have also used hoses and fittings, as have I, but the sheetmetal manifold provides the best volume of water, and is less complex than fittings and hoses.

    I sell the adapter plates for $259 for just the plates, $275 with the valley cover plate, and I can do all the welding for you on a standard deck height block with unmilled heads.. for $750.. with your mopar manifold.. you then have to fit it to your engine's deck height and gasket thinkness desires, and the milling cleans up any minor warpage that occurs from the welding. You will also have to port match the manifold/adapter plates to your heads, there is plenty of room for port matching.

    This setup is typically used with either a MP performance manifold for NHRA Super Stock, or with an Indy 440-3X manifold for big cubic inch drag race motors 750 HP and above.

    ----------------


    Currently available for the high port heads only, but I am working on a Standard/Stage 1 adapter plate setup.. since I recently verified that this manifold will fit under the hood of a 64 Skylark, with just a minor trim of the hood inner structure.

    I was surprised at how close the hood came to shutting, with no trimming..

    with the hood closed, we see the interference point.. just a minor trim required on the inner structure.

    And the beauty of custom fabrication... we are considering running it this way, with an air box built in conjunction with the cowl. :eek2:
    Serious Boost guys, running a water/air intercooler in the car, should be interested in this possibility.

    I am beginning to lean toward the fact that while these self learning throttle body systems have their place in the market, to get all the true advantages of EFI, we must go the rest of the way, with a dedicated intake and laptop programmable control system.

    We will see.. I will be doing comparison dyno testing with this one, as well as building the car and getting it on the road for evaluation.

    This one will be a 560ci Tomahawk.. :TU:

    I'm more interested in what rocker arms you are going to use on that.

    Same car/same package........ whole stack of 11.67's-11.70's, 11.66 still the best. Car spends most of it's time sitting now, I went self-employed and just haven't had the time/money to work with it. I'm starting to put together the parts for a big stage II effort, I don't know how hard I'm going to push it at this point. It will be EFI with a "different" or "interesting" style of intake manifold. It will be a tall port stage2. It will be a production block filled and girdled. I'm not sure if it will be oem crank or aftermarket. It may be aluminum rods I haven't made up my mind on that yet. It will probably have custom Jesel or T/D individual shaft rockers, I want more ratio. I would like to go with offset lifters/pushrod holes so I can fit larger pushrods. We'll see how this all shakes out.

    If I sell my 6.0 LS I built as an efi training mule that will pay for heads/rockers/porting.

    Jesel Pro Series Individual cylinder pairs.. 1.65/1.70

    The heads and intake shown here actually belong to the 555 centrifugally supercharged motor going together now.. that customer has a 65, so it made all the sense in the world to fit them on this pro-touring '64.

    Jim, this is not to intend to piss anyone off, has anyone read or done efi intake manifold testing on runner length? I have talked with many of the efi makers and tuners about this subject. They all said the same thing to me. Its great you are gonna test the differences in self learning and the ones you gotta miss with. The bbb is a hard nut to crack for sure. Tuning one will be fun for sure, especially a 650 hp bbb. Please read and ask questions to efi makers on intake manifold runners. You'll be surprised. Nice write up jw.

    Why not use Robs plates with the SPX?
    no welding or waterjacket fab required?

    Hi Dave,

    He's going to adapt a "different" manifold for his project.

    I'm not planning on using the SPX....... or any single plane manifold for that matter.

    Well inquiring minds want to know what intake you are adapting?

    Cross-ram (converted to efi and single front mount throttle body or an I.R. -- haven't fully made up my mind.

    And just so you know how unhinged I really am, here is the 385 inch small block in my 3/4 ton 4x4 crew-cab pickup I use for pulling trailers. 500 ft/lbs on 87 octane.

    it's going to be a while, I'm just gathering parts. It's not cheap to do these things so a little here and a little there.........

    Oh I understand. I have a three year project going now. Sure do miss driving my car!!! All the best on your build.

    I'm assuming you are wanting all the torque avaible? Its gonna be brutal.
