    Got a box of parts Friday and now I have a few questions I need to ask (e.g. does it matter which way I orient the 4 bbl carb?). Any chance you would be so kind as to give me your number so I can call and get your input? If not, I understand.

    Thanks for the quick reply. I don't see a reply button so I must be limited in my account as a newby.

    I am in Lewiston, just down the hill from "scow." I take it you were in school there? I teach at LCSC. Yes, dark at 4:00 sucks, but light until 10:30 is nice in the summers.

    You got it; the feedback carb is dying, along with all the electronics that go with it. When we first bought it it would get 12-13 mpg, but now it is closer to 6-7 mpg and you can smell the unburned fuel coming out the tailpipe. We tired new plug wires and rotor cap, cleaned the carb and re-calibrated it, but I think all the cleaning did was expose a host of problems we never knew we had. Based on your recommendation I'm going with the QF 450 slayer. Black would be nice but I can't justify spending an extra $40 for something no one will see.

    Thanks for your time and advice.

    Hello AB,

    I'm a little north of you and in a different time zone, but still the same great state.

    I found my son an 85 F150 I6 4spd 4x4 LB with 42K miles last fall. It runs fairly well in stock condition but recently the carb has had some issues so I decided its time to do some upgrades.

    I have spent hours reading over the intake, exhaust, and ignition mods and your posts have been especially helpful. One thing I can't find is where you talk about your switch to the QF 450 carb. Do you have a write up on that one? I'd never heard of QF till I saw it in your signature so now I am researching it, but not finding much. Do you like it? Why did you drop the Holly 600? How is the MPG?

    What I am looking for is a rig with reliability, dependability, and good fuel economy; going fast is nice too but not nearly as important as the other three (plus the fact that he is a teenager :-) )

    Thanks in advance,

    Hi AB:

    I live in Boise as well. How's it going? You seem to be dialed on rear end gears and I'm struggling. My rig is a 66 F100, 300 IL 6, 4 speed manual (first is basically the granny). The stock rear end gear is 3.50 and the truck is geared way too low. It is screaming on the highway at 60 mph. Based upon other commentary on this site and looking at gearing calculators, I'm leaning toward 3.0 rear end gears. Do you have any advice on this? The truck is entirely for towing and I plan on plenty of road trips in the future. Could you weigh in with your thoughts?
    Thanks much, Doug

    AB, I was reading the "Distributor recurve" thread you did a few years ago. I'm pretty getting pretty close to doing that myself and I was wandering what you finally settled on for springs and which slot you used.
    Also thanks for all the time you've put into this forum. I've learned more here than probably everywhere else combined.

    AB--hello to you. Does the Walker Y pipe have a flaired end, allowing a 2.5" pipe to slip inside it?

    Thank you very much for your quick response. You have confirmed what ive been thinking. I got the engine running the other day, runs like a dream! Its my first ever engine rebuild so i must have done something right so far. So far has loads of power in mid rpm, a little lacking in the upper. Havent pulled yet, going easy for a while. Good to meet you, your postings have been a great wealth of knowledge for me over the past year or so in my research of this engine. 1967 ford highboy, 300ci 4 speed, 4.10, 255 85 16. Engine: 9.2cr, .040 over, comp cam 260, cloyes advanced timing gear, 240ci ported head, 3 angle valve job, clifford intake, 2100 autolite, 300 HD 2.5 in single exaust manifold.

    Hello AB, I live just up the road from you in Mountain Home. I need your opinion on a cam related topic. I just rebuilt my 300 with help from an old school hot rodder. Upon inspection of my original stock cam, i noticed the spacer ring for the first time. I didnt put it in... Oops. I was very careful when pushing the cam gear on, to watch for proper clearance between the gear and the thrust plate, unaware of that being the purpose of the spacer ring, which I had no idea about. I have a very tight clearance, but the cam spins free and smooth. My question for you is, is that the only purpose of the spacer ring? If I am comfortable with my clearance, can i get by without it? Is there a chance the pressed on aluminum gear could some how "walk up the shaft" seeing that the gear is aluminum with helical cut gears that could be prone to side load? I see no other use of the spacer ring other than clearance. Its a Cloyes aluminum gear, and I really dont want to pull it off.
