Bronco Carb Options

Post #1 by ledslinger29 » Sat Nov 23, 2019 9:30 pm

Hey Fellas,
I have a question for those of you with Bronco knowledge. I’ve grown tired of my 1100 on my 170. Have any of you put on a Weber 32/36? If so, did you have to modify the head at all, what did you do about the throttle cable, and did you have a problem with hood clearance? My carb has some issues that will cost me more to fix than it’s worth, and I’d like to get a little more go out of my little motor, but I don’t want to spend a pile of money on a dead end road. I’ve already got a DSII distributor from Bill.

Bronco Carb Options

Post #2 by chad » Sun Nov 24, 2019 11:03 am

I've enjoyed watchin ur build'n comments here over the yrs, not sure I have much to offer (beyond what I C here & experience in 37 yrs of bronk ownership). 1st off I would say - there is less need to ask bronk specific Qs. It's the same motor w/the same issues as a falcon, stang or any of the others - low hood (I do have some ideas gathered here 4 that), poor 'breathin', dyn0mite bottom end (ever have ur pan dwn to look @ those huge counter weights on the 170 crank) & so forth. The only reason I am in the process of a '69 250 swap is the cubes. I have not put on the RBS, am just now locating the motor in the frame & fabin the 250 'ring' to the 170 sump.

I choose the RBS as 1 of the 6 or 8 'low hood' wrk-a-rounds (W/advisement frm this site as a 215 cfm carb - possibly 'choke' ur 2.8L). U can look to the many threads here on the webber/holley progressive on any vehicle we address. There should B several on the current Index page (Ryan's most recent?) and those following, the Handbook & tech archive above. I seek tq & choices have tended toward largest i6 & largest 1V. I believe U want streetability and the webber seems a good choice (but tall & not a hi cfm for that optimal app - which is AFTER ALL - The primary Q 2 answ). ? Holley 4V 300 cfm ? I just DK~. Keep talkin, let us know how U do...

I seem to remember that Weber carb needs an adapter so not sure about hood clearance problems. I have become interested in the Carter BBD carb it is a 2 barrel that can direct mount to the log head if you hog out the opening as some members have done and reported very good performance. They have not been made in years but a Chinese version is less than $100. I am considering it for my Bronco.

Yep that is it. Apparently they are available in three cfm ratings. I will find the post from the member that has done this conversion and provide the link. I like it because you avoid expensive machine costs and leave head on vehicle. And down the road you can still direct mount other carbs if your plans change or put original carb on.

That looks like a viable option, as I don’t want to have to modify the head if I can help it, and I can go back to the 1100 if I need to later. I’d like to see the post for sure, bmbm

It was 63falcon4drwagon who did this mod and first brought up using a BBD. At the time I was looking at this carb b/c of its size. I'm still planning to use the 2CG version of the Holley Sniper version of the BBD. I would guess you'd want the 6 cylinder jeep version of this carb for you're 170 if you can make the linkage work. If you have a small log on you're 170 I'm not sure there is enough pad to do his mod.

He also mounted a Monojet:

Also, there have been several guys on my van forum that have installed those "universal" 1 barrels on their 170's and been pleased with the results. They have an adjustable main jet. And you can install a weber with the Vintage Inlines adapter if you have enough hood clearance.
Good luck. And then there is the LOM distributor issue.
It ain't gonna fix itself

Good tip about the 170 head having enough pad to hog out.

I like that we R getting threads for specific carbs.
WIsh there were ways to sticky them. But...
I feel the same abt "specific heads" ('early', 'hex', 170, 200, late, etc). Rear ends ina 60s, 70s ford'n more, Seems like
it would B a bear to slice'n dice into 'a table of contents' type listing. My bet is
it would enhance our usability as a site. How bout this?: I;m willing to do so for
"All posts on 2V carb mounts on all i6 sm block falcon oem heads."

U guys got me goin ta nite !
Did I subscribe to deeply inta rbohm's signature line ?
