    SixPoppin: My post was too long. Here is the 2nd half:

    The QJ is a fantastic carb but it can take A LOT of work to dial one in. I love the '1705' models, made from 76 to 80. Those have a adjustment for cruise that no other carb has. It allows you to tune, with a wideband A/F gauge, to dial in how low/high the needles sit in the jets, for perfect mpg. The limitation of the QJ, as with the 4100, is dialing in the accelerator pump shot. As you know, every time you let up and then touch the gas again, you squirt a shot of fuel into the carb, and that is a major factor in city mpg. That is why I finally went with a Holley 1848, a 465 cfm carb. With a Holley I can change the acc. pump nozzles for more or less fuel, and also the cam that determines when and for how long the squirt goes.

    I would also do the math and calculate what rpm you'll be running with those tires in 5th gear at 60 mph. Good luck. kevin.

    Hello SixPoppin': This could be a long post. Let me start by saying that Autolite/Ford put some 1.08's on big blocks, so you might get lucky. Get the numbers on the toe on the throttle side, and run them on mustangtek dot com. That will tell you how it is calibrated. Don't be afraid to run a bb 4100 on a 300. It will do fine. Just be cautious that the t.shaft is not a vacuum leak. It should be good for your needs. The limitation with the 4100 is parts and cost. Also, no one cataloged the codes stamped on the booster clusters, so you can't tell if, after 45 years it has been changed, making it a tuning nightmare. It is in the cluster the airbleeds and boosters are.

    I have been reading your posts about carbs and the 300 with much interest , so I decided to join up and ask some questions. First off, I am working with a 79 F150 and am swapping in a 95 300 in the next week or so. The rig currently runs 35" tires and 3.50 gears. A NV4500 5 speed trans is also going in with the 300 I-6. Motor specifics: Offy DP, Comp cam (206@0.50/260 gross X lobe), stock EFI ex manifolds. I already have an Eddy 500 carb (used). I am more interested in the Autolite 4100. My cousin has a bunch of them, his grandpa had a shed stacked with Mustang parts and the stuff has been untouched for decades. He likely has a 1.08 or two in there, but maybe not since Johnny's cars mostly had big motors. I am curious what your comparison is after a running sleeved down 1.12 carb, the 1.08, QJ, Eddy, etc. is. I am primarily interested in MPG and torque at low to mid rpms. What is your take on all of this?

    Gotta call 'em but I just read through their guarantee and it's unlimited mileage but only good for 12 months. There is no hurt in trying to work something out if they are willing.

    I haven't heard any bad things about Red-Head. I'd call them to discuss the matter.

    I noticed you sent a message to AB asking about the walker y pipe. It is not flared at the end to accept a 2.5" OD pipe.
    I just fought two of these pipes a few weeks ago, if you're interested I can pass along the issues I had and maybe save you some troubles.

    Do you still have this unit?
    Borg/Warner T85N & R11 overdrive. I'm in San Diego. Where about are you located.

    I saw you were on line and was wondering if you would take a minute and look at the post I made and see if you can help?

    Greetings, found a post of yours before I joined looking at your pics of hopped up 300s, which photo is YOUR project? What brand of header do you use? Do you have the original source/link of the photo of the engine with the yellow wires? Thanks

    Thanks bud, for everything. I've been reading this site for years and youve helped me out more times than you'll ever know. I just recently saved up enough to get the rest of the parts needed. The carb is what took the longest to save for. Unfortunately the headers where the first thing I purchased a while ago. I had a buddy ceramic coat the outside and the inside with something else but I can't remember exactly what it was. I'm hoping this will help but after reading your post I expect to have to fab a heat shield.
