    Default Holley 4118-S

    Does the 725 CFM Holley 4118-S carb have skirted primary boosters like the 735 CFM 428 CJ carb or standard downleg boosters?

    Thanks,
    Dan Jones

    I have one under the bench; I'll go down & look. Any other questions?

    Default 4118-s

    It has down leg boosters and manual choke.
    On the air horn, beneath the 4118-S is 231.
    I've not used it for number of years.
    Tried it with 351W; but went with 3310 that had
    secondary block not plate. (780)
    I don't have a home for it.

    4118 came with a climatic choke.

    Probably somewhere in the last 50 years it's been altered?

    > I don't have a home for it.

    One came up for sale locally and I was hoping it was similar to the 735
    CFM Holleys that came on the 428CJ's. I'm a fan of the skirted boosters
    but perhaps the 4118-S would still be a good match to the combo below?.
    I'm gathering parts for an I engine I'm putting together for a friend.
    He has my mom's old '71 Mustang convertible with 302 and the AOD I swapped
    in. I tried to talk him into one of my 351C's but he wants to stick with
    a 302 based engine. I also tried to explain the cost of premium fuel is
    offset by better fuel economy but he wants to stay with 87 octane. It has
    power steering, power disc brakes, air conditioning, and Global West subframe
    connectors. This winter, he's painting the car and putting in a new interior.
    The engine isn't slated to go in until next fall so I've got plenty of
    time. Tentative plans for the engine are:

    5.0L hydraulic roller block
    hydraulic roller cam with 1.7:1 intake and 1.6:1 roller rockers
    Boss 302 windage tray
    SCAT cast crank, forged dished piston, 331 stroker kit (9.3:1 with 58cc heads)
    C90X dual plane intake
    Floo Tek cylinder heads (1.9"/1.6", 58cc's)
    headers with dual exhaust (maybe Flowmaster mandrel bent tailpipes and Magnaflow mufflers)

    It still has the original 8" rear end end and gears so it'll need a higher
    stall speed convertor. The AOD was from my dad's old 1990 Lincoln Town Car.
    It was rebuilt but will need a shift kit installed and perhaps the Thunderbird
    C-servo upgrade. The goal is to make 20 MPG on highway while making good power
    within the budget and shift points of the AOD. Alex, a few quick questions:

    What's the largest size intermediate pipes that will fit past the convertible chassis
    reinforcement plate?

    What headers do you recommend (coated or plated would be good) with the AOD
    and power steering?

    What stall speed convertor and shift kit and what would be the shift point of
    the AOD?

    B&M AOD shift kit is the most user friendly.

    We used custom 2.25 exhaust on a customers 73 351C project from a couple of years ago.
    It all fit very nicely under the factory reinforcement plate.
    We used Magnaflow mufflers and a Mach one rear valance so the tail pipes could go straight out the back.
    Between the hood, rear valance, and paint scheme we pretty much turned it into a 73 Mach 1 convertible.
    We have a very inexpensive TSI 2500 stall AOD converter that we carry. It works great for most warmed over street applications.

    A nice set of small tube Flotech (Hooker secondary line) long tubes will fit the AOD with minimal tweaking and give you power, torque, and great cruising fuel economy.
    I do not recommend the coated ones as the coating is crap. (on all brands)

    > B&M AOD shift kit is the most user friendly.

    Leaving it in gear, what sort of RPM will it shift at?
    I need that to design the cam. No use making peak power
    above the shift point because Bill will not manually shift
    it.

    Did you stay with 2 1/4" on the mufflers and tail pipes?
    I was thinking of stepping up to 2 1/2" at the mufflers.

    Cool. I wass thinking of the Boss 351 lip spoiler, a set
    of Magnum clones. Will 245mm wide tires fit all way around?

    Sounds good. I'll add it to the list, along with the headers below,
    Melling select blue print oil pump, FRPP billet oil pump shaft, B&M
    shift kit, aluminum water pump, Comp double roller timing chain set,
    mechanical fuel pump and distributor with steel gear (the car has
    an MSD box, BTW).

    Sounds good.

    Okay. Do you have a local coater you trust or should I look
    for one around here?

    Shift points depend on the governer used.
    A typical 5.0 HO AOD governer will shift out at 5200 in drive at WOT.
    We can supply you with one of those as well.

    Yes, we used 2.25 in and out on the exhaust system.
    351C 2V with some compression, a little head work, Hooker long tubes, Performer intake, 270H cam, 770 Avenger carb, and very good hot ignition.
    All behind a JPT C-6.
    It flew for what it was.

    We installed Firestone 500 RWL 245 14's on the stock 73 slotted aluminum wheels and they fit fine.
    All new front and rear suspension. Ball joints, tie rods, etc. with new HD Moog front coils and 429 5 leaf Eaton rears, KYB gas shocks. Probably raised the car 1/2 over stock.


    We use Nitroplate Coatings exclusively.
    Obviously not local.
    I have not found a good coating company in IL when we were there or in IN since we moved here.
    So, we tried Nitroplate, loved their work and stopped searching.
    Pricey with the shipping back and forth, but the quality and warrantee along with piece of mind is worth it.
    Average headers are $249-$329 + shipping.
    No more complaints 30-90 days later as we got with every brand of coated boxed header.
