Original Carburetor on 73 Bronco 302?

[malibubronco]

I have a 73 with a 302 V8. What carburetor was original equipment on these?
Thanks

Hi, 1973 was the first year for the Motorcraft 2150 carb.
There are different model 2150s, automatic vs manual trans. for instance.
The carb had a metal Id tag on it to identify exactly which 2150.
I wouldn't be surprised if some 73 Broncos came with the earlier 2100 carb.
Good luck

Great, thanks. When I got it (12 years ago) it had a Holley 2bbl.w/ electic choke. I replaced it back then with an Autotolite 2100 manual choke. Thanks for you help! I want to keep it as stock as possible.

And '73 might have been the first year for the carbs to have the float-bowl vent on the top that had a hose down to the charcoal canister. Might have been a CA only thing for the first year or so, but I'm pretty sure that was the first time I saw the bowl vent added.

Some carbs of the vintage will have the boss cast into the top cover, but is not drilled for the barbed hose fitting.
A proper carb for evap fitment would have the fitting sticking out the front of the top at an acute angle.
Not sure if anything would be left, but if your original charcoal canister is still on the passenger frame rail, you might see where it had an additional hose from the carb.

1975 was the first year for 2150 Motorcraft carbs. The '73 and '74s came with 2100s with a vacuum choke pull off, but not the same pull off as 2150s. The 2150s also had air bleeds that got smaller as the throttle opens. I've used plenty of both and have found no advantage to either. They both work better than any other 2bbl. Here's a good example of the 2100 you should have.https://www.ebay.com/itm/1973-1974-...924240&hash=item44544bac2e:g:0eUAAOSwoCFeQ3yZ. The 302s got 1.08" venturis.

Wow, a NOS Motorcraft carb. If I ran a 2 barrel I'd buy that carb. I love NOS parts.

Hi, I got the first year for the Motorcraft 2150 carb as 1973 from info in a Chilton's manual.
A Wikipedia check also lists 1973 as the first year. Good luck

Sorry didn't mean to embarrass you. I thought the fact that 2150s were introduced in the '75 models was common knowledge. Not that I need Chilton's to find this out, but in my Chilton's Ford Bronco 1966-86 page 196 they clearly state the 2150s were used in 1975-1978 Broncos. The 2100s were used in '66-'74 Broncos. Good luck.

wondering if a car 2100 would work - concerned abt the gradients'n slosh.
Some1 on Pirate modded this fantastic 2v for off rd use.

Want to do a direct mount (mill head on i6 250/4.2) and see the e-bay models w/a lill 'pot' underneath that seems like it might interfere w/a nice flat mount...

The only difference between the car and truck 2100s is the choke. Trucks often got manual chokes and the cars got automatic chokes. 1973 Broncos had automatic chokes. Some of the early '70s truck 2100s including the '73s had shorter bowl vents. I don't see any advantage for off roading. Fuel isn't going to get sloshed out of the bowl vents. Look at the top cover gasket. There is no hole below bowl vent like Holleys. Fuel can get above the gasket, but that's all. The '73 2100 is hard to improve on. The Jeep guys don't see that if it's not broke don't fix it.

Thnx 4 da post back,
"...2100 is hard to improve on..."
I'll say. Might B the best 2v out there, tunable too.
OK, if no fule starvation on the side hills, frnt'n back gradients (4 way) I might try it.
When U say 'jeep' do U know their set up for the 258? (jets, etc)?
(The 'pinto' or weber 32/36 caught my eye too but that's a different story).

Malibubronco........in Galveston for the weekend but have several 2bbl carbs. Lemme see if one is a 2100 or a 2150.

 

[malibubronco]

Thanks Far Side!

Bronco 2 barrel carbs had a damper spring on the float rod. this helps off road. car carbs usually didn't have this.
