I just wanted to say hello...I've been lurking here for a few weeks as the "new" owner of an "83" F150 and have enjoyed some info I have gleened here. I'm not new to Fords, but haven't owned an F150 before i guess. (My first Ford was a 49...second one a 55 etc)..My last "big" Ford was a 94 E150 Leisure van I enjoyed and maintained till I sold it last year. I also owned and maintained an 88 Bronco II and enjoyed it till I sold it last month. I also own an 84 Bronco II.
I am familiar with EEC-IV stuff, But have decided to drive a carburated vehicle for the duration I think...I have accumulated a few early 2100's and some 2150's and enjoy tinkering with them. I am "dura-sparking" this 83 currently and if anyone near me needs a helping hand I am generally available if the need arises...Good will to all and if you don't mind a question or two now and then I may speak up again...In the mean time... I'll be listening ...

Thanks for the welcome man.(ctubutis) .I've enjoyed your comments here..I actually had to laugh at myself..I actually owned a 99' Lightning...i guess it WAS an F150..albeit a very tuned one..I bought it new in 99 and put about 38K miles on it. I think it was about the neatest driving PU I have ever owned, even got about 18mpg when driven sensibly.. Reminded of a 56 F100. I just wish it had had a Y-block 312 for power. It would've made a neat keeper for sure. Lotta power though..again thanks for the welcome...
but as of now..no response..I probably should've made this post here since most of the guys here seem to be up to speed with the unique needs of trucks of "this vintage"
Anyway w/o doubling up..it pertains to the use of a 16 bolt intake (early 351w) on this 83 I have. I haven't had the intake off of a v-8 since 312 days..I have an opportunity to score a cheap 2v iron manifold from a 69 (I'm eliminating the EGR) and wondered what the fitment issues may be with this newer E7 head ..well if any here know feel free to chime in and thanks for the input in advance..
John - Welcome to FTE. I've not used the earlier manifolds, although I've read about them. But, I have to agree with baddad - why? The later iron 2V manifolds are easy to come by, but the aluminum 2V manifolds are available as well and a block-off plate for the EGR is easily made. Having said that, if you have the manifold off why not put on a 4V? Used ones run ~$100 on CL around here and 4bbl carbs are $75 - 100.

I'm just in the diagnosing stages with this engine..it barely ran when I parked it in the carport, and when I found it had the DSIII mess I started the process to DSII' it and as part of that I will remove or block the EGR and etc etc..just to get it running smooth enuf to take it to a muff shop and "streamline" that system if you know what I mean. In the long run I'm sure i will put some sort of 4bl setup on it..but I want to drive it for a while to see if it cleans up enuf to spend the effort on a manifold change ...compression is good, at least consistent, probably a lot of carbon...It has ran for at least 60k miles without a feedback carb on it and everything else hooked up so it's pretty carbon-ed I would imagine..again thanks for the comeback...I've read your posts about your setup and enjoyed the reading...this morning i had to get back to a seller on the local clist about a manifold he had but he wasn't sure how many bolt holes it had so I wanted to be sure of the process b4 getting involved... we'll wait for the right one to come along...have a neat day all...
Good plan. And, btw, a 4bbl isn't everything and I'm not suggesting you need to change. The '82 Explorer I sold had a 351W that I built with a low RPM torque cam and heads I ported that flowed through factory manifolds into a "streamlined" exhaust. That rascal ran even with the 2150 on it. In fact, I was very happy with the performance and am not sure I would have gone to the trouble to change to a 4bbl.
However, if I pull a 2bbl and am going to keep the truck then I'd seriously consider installing a E'brock Performer manifold and E'brock 1406 carb.
Do you know what venturi size the stock 2150 was? The carb on here now is 1 1.08. (the feedback one is gone). I'm curious what venturi would work best with the stock 2v manifold and along with that what would be the ideal jet range for say sea level-3000 ft any idea? BTW I like these 2100 autolites...for smplicity and would stick with one i have already most likely..

No, I don't know what size the stock one was nor the one that was on it. Originally it was feedback but the "mechanic" that the PO hired to change it out threw it away, literally. And, I've since sold the truck so don't have access to measure the one that is on it.
However, I will say that the #'s on that carb say it came from an '81 351M with C6. So I assumed that it was the same as the one that is on Dad's '81 351M w/a C6. But, when I pulled this one down the other night for a rebuild it was very different. For instance, this one doesn't have metering rods while the other one did. And, the choke on the other one was fully electric, and 7 volts at that, while this one is hot-air with electric assist and it is 14v.
and I actually have a couple original 84 feedback carbs from Ranger/Bronco II's that are 1.08 venturi . Can I ask what venturi is the carb that is on your current project?..
I actually will use an older 2100 variant i think..and I have a couple good cores with non-kickdown throttle shafts to use and they are 1.08...I guess I'll kit one of those.
My 83 has a feed wire from the S term on the Alt which usually is lower voltage than line volts. I'm not particularly a fan of electric chokes in general i think I will use a hot air automatic when i get that far running with a choke stove tube from the manifold. I also have a choke housing bracket that allows the passing of the heater hose to help keep the choke warm so I will use that I think..again when i get that far...right now I just want to see reliable exhaust coming out the back end of the truck not all thru the undercarriage...well in time I guess...
I'm off to get a friend to fab me an EGR plate from my valve...then I'll finish up my "spark" wiring.. I may fire it up this weekend but there is no rush..thanks again for the input...

I don't know which size carb this is. It is the original on an '81 351M, but I don't know the spec's.

Thanks for gettin' back. For curiosity sake I've been researching most of the usage of the early 60's thru 80's Ford carb uses when working on another project and found that some years used a 1.14 venturi variant, or a 1.22 variant..as noted on the driver side view of the fuel bowl on a 2100/2150 generally. Referred to as the "clock face" with a number in the middle..that is what I'm referring to. I think that they can all be tuned within reason as long as they flow enuf air thru the venturi's..for the cubic inch needs..and are jetted correctly. I actually would prefer to have mid-late 60's manual choke version if i could find another one..I have one I'm using on another project.. My quest for good mileage vserformance is why the search..stretchin' that petrol dollar..thanks again
I'll look and see if I can tell on this carb. But, depending on the gears you are running you may be chasing your tail re MPG. I'm thinking the key is to reduce RPM.

For sure. In my case packing a CAMPER (a brick wall) and going much faster than 45-50mph or so for as short a distance as possible and enjoying the surroundings of trees and creeks etc for a few days at a time will be the best I can hope for i think.. This 83 has a 3:55 L/S ra and with a direct drive np435 I don't think I'll be setting speed records..If i can get it to and from and have a grey tailpipe I'll be happy...If I can sit at a campsite with my accommodations in the back I'll be gettin' my money back..
On edit..I should add that for me driving anything that is NOT computer controlled and easily maintained by me is part of the smile of this process...
