2 barrel carb recommendation

[79_Limited]

What's the best 2 barrel carb for my stock intake?

I have a Motorcraft 2100 that I destroyed. Any better replacements?

I will mostly be doing mixed city and highway driving.

Yup that Holley is a nice Carb! smile.gif

yeah the holly t500 was a great carb ,it would work side hill and up and downin the old days,i like the new ones with the full vent tube and spring loaded valves and dampened floats those engineers really listened to the offroad people about how something needs to work

I just yanked one of those the other day at the yard. I've got it downstairs soaking in carb dip and stinking up the place (even with the cover on). Found them rebuilt online for about $218.00 but if you would like to do the rebuild yourself I'd be very willing to part with it. Just snagged it because the rebuild kits aren't too expensive bout $35 from Holley with good quality gaskets and such. Drop me an e-mail or PM if you would like to know anything further.

How well do the Holleys work in the cold weather?

My motorcraft was rebuilt last Feb. and I am already having problems with it again.

Is the holley 2300 series any better than the 2100 / 2150 motorcraft carb, other than being slightly more cfm? I'm still trying to sort out which carb to use on my 258 and was pretty much sold on a 2100 but if the holley is a better carb I will go that route.

My experience with a 2300 Holley vs a 2100 Motorcraft was ... Holley was great on the street, but troublesome off-road. Unfortunately, I found that there were some attitudes where the Holley would not run unless I kept pumping the throttle. The stock 2100 (304 CJ) would run at any attitude. The Holleys are a really nice design, very tunable and easy to take apart and put together. However, I think you'll have to add a lot of Holley accessories and raise the float bowl vent to get the stock 2300 to work well off-road.

I just recently replaced the stock Motorcrap for a 2 barrel Holley. I love it. However. Due to transmission woes, no off-roading at this point.

I've let the truck sit for as long as 2 weeks. Each time, she fires right up. At a cost of $189.95, I'm happy.

Janie I remember reading your post where you said you really liked the Holley.

Where did you get yours?

Bryan, I'd advise using a 2100/2150 (used) or a Weber (new) - both tried and true. If you go Motorcraft, look around and find a good one from a '70s or 80s Jeep V8 Jeep. It will have the float damping spring that I believe was only available on the Jeep versions.

The Weber will only cost at most $100 more than a new Holley, once you add all the Holley accessories that you'll need to make it work well (side pivot float, vent whistle, fab a bowl vent, spring loaded needle, jet baffles and their special float, etc).

[Bryan]

Thanks Tim, thats the info I was looking for. I think I'll stick with a 2100 motorcraft. I really do need it to work offroad at different attitudes so sounds like thats the cheapest way to go. I just cant afford a weber right now. Maybe some day!!

Oh BTW, any recommendations on a 2 bbl manifold, such as year etc... I'm currently using the stock 1bbl carter, which is actually good carb just not much power.............

There was a thread about this recently:
http://www.ifsja.org/ubb/ultimatebb.php?ubb=get_topic;f=2;t=024387#000004

You have three choices: the cast iron intake/exhaust from a '77-79 (or 80?) 258 FSJ, the aluminum intake and cast iron exhaust from a post-80 Jeep 258 (CJ or FSJ), or a 2V manifold from an AMC car. I don't know much about the car manifolds, but I believe you can use a header with either the cast iron or aluminum Jeep intakes. You cannot mix exhaust manifolds between types though - you must use the exhaust that matches the intake or go with a header.

hth :cool: Tim

Thanks Tim, you da man!!! I guess I should have gone back and followed up on that other post since I'm the one who started it!!! Hey I noticed on the photo with the newer aluminum that it looks like your using a copper seal gasket?? Is that the recommended type?

[tgreese]

Nope - regular Felpro gasket with some spray-on Permatex Copper Coat.

Glad that helped! best regards :cool: Tim
