    (This is a good way to save a few bucks, and we know how Stude types like to
    watch their money)

    Want to easily improve the performance of your Studebaker V8 engine?

    Install one of these manifolds and add an AFB carb (Jeg's/Summit, AutoZone,
    etc.) and away you go.

    A 500 cfm electric choke AFB is recommended for 259 V8, and stock 289
    Studebaker V8 engines. Carter (Federal-Mogul) p/n 9504, or Edelbrock p/n#

    For modified Studebaker 289 V8 engines that have a hotter cam or performance
    work you can go with a 600CFM AFB. There are three choices here. Edelbrock
    p/n# 1400 (600 cfm jetted for economy), Edelbrock p/n# 1406 (600 cfm jetted
    for good street performance), or a Carter (Federal-Mogul) p/n#9635 (625cfm
    electric choke). All are electric choke versions. You will need to convert
    to the electric choke to keep from having linkage interference with the
    choke tubes and the secondary throttle linkage.

    This is a less expensive alternative to finding a WCFB 4bbl manifold and
    modifying it, not to mention the expense of finding a good WCFB core and
    having it rebuilt.

    These manifolds have been modified to accept an AFB carb without
    interference between the secondary butterflies. No need to run that thick
    heat insulator to clear the openings. ( but you still can run the heat
    insulator gasket to gain the heat insulating benefits). The stacked heat
    insulator gasket is a Mr. Gasket p/n# 97, or an Edelbrock p/n# 9266.

    Besides milling the carb mount surface flat, the intake plenum to manifold
    runner radius has been rounded off and smoothed to improve airflow. The
    plenum inlet has been milled to the larger throttle bore profile, and the
    profile has been machined all the way down to the plenum floor (to decrease
    turbulence and enhance airflow). The carb mount stud holes are all drilled
    in the milling jig to assure the studs are straight and square. The intake
    runners have been port matched to the stock Studebaker steel intake gasket,
    so this manifold will flow better than stock, even on stock heads. The
    casting flash on the outside of the manifold has been ground off for
    cosmetics, and the manifolds have been bead blasted. The outside of each
    manifold has been painted (black or silver), and the intake runners and
    plenum have been sprayed with clearcoat to prevent new rust.

    More pictures of the manufacturing process can be viewed at:

    No studs are provided, as the length may vary due to your choice of adapter,
    riser, or gasket package. Stud kits are available from Mr. Gasket (p/n# 50
    for 1&3/8" studs or p/n# 60 for 1&1/2" Studs), or from Edelbrock ( p/n# 8008
    for 1&3/8" studs. or p/n# 8024 for 1&1/2" studs))

    Shipping will be UPS. Weight of manifold is 27 pounds, so with packaging it
    will be right at 33 pounds. UPS from Florida to Seattle was $30.. Missouri
    was $22. You can figure your freight accordingly. I will figure it exactly
    on completion of transaction for you. $5 packaging to make sure the cast
    iron manifold isn't crushed and pulverized by shipping gorillas and arrives
    to your doorstep in one big piece, like it is supposed to. No surprises.

    You will have to send me a 2bbl manifold (late model) to qualify for this
    price. PLEASE, don't send me a greasy slimy core. Dirty is OK, slimy isn't

    Graduated discount for 2bbl cores. The exchange price for a modified
    manifold is $99.95. If you have extra cores, I will extend a $10 per
    manifold discount toward your purchase. So, if you sent me 10 manifold
    cores, yours will be FREE. Will also purchase manifold cores outright for $5
    each. Would pay more, but freight is a deal killer. Will consider pick up of
    cores if logistics can be worked out.

    If you want to buy a manifold outright, you can purchase this same manifold
    outright f

    This is good and easy way to install a 4 bl carb. I first did this myself when I was 15. I was rebuilding my Dad's 60 Hawk engine and installed an R1/R2 cam and modified the manifold to accept an AFB that came from an early 60's Buick. I actualy did all of the work by grinding, filing and using a drill press to drill new stud holes and the new holes(with a hole saw) for the 4 bl. I probably spent 4 or 5 hours to do it by hand but it didn't cost anything. The $99 price is quite reasonable.
