New carburetor

[matrixx]

OK so if some of you have been following I managed to get my car started and the Carb was leaking a lot. It was rebuilt about 4 years ago when previous owner had it but couldn't seem to do it right. Well anyway I took it back off the engine and turned it over to a buddy that has a lot more experience than me dealing with carburetors and I just got the news that it a lot of the insides were tampered with and broken and that it would need more than a refresh kit. Long story short Im in the market for another Carb. So I'm turning to you guys to point me in a right direction. I'm not looking for anything performance persay at the moment I just need a standard military issue 4 bbl Carb for my 302 that I can put on and at least get the car moving under its own power so I can start the rest of the work on her. Thanks in advance guys!

What type of carb was on the car? Holley, Edelbrock/Carter, Motorcraft?

Parts are obtainable for all of them to repair or rebuild.

I wouldn't use more than a 600cfm carb on it if close to stock or modified.

Some folks tend to over carb engines thinking it produces more power, but if the engine can't use the extra air/fuel mixture it's all a waste.

The Holley model 1850 is a generic, square bore 600cfm with vacuum secondaries that generally provides a good carb right out of the box.

Usually have to jet it down a few sizes, but overall a good carb.

Yes its a 1850 Holley 600 Im not going any bigger. I know there's rebuild kits but it seems like this one has seen way better days. Can you still get these new?

Recently bought a Holley from Summit Racing to replace a Holley I

bought from them four years ago. Not because there was anything

wrong with it (gave the old carb to a forum member), but because

my recently installed rebuilt engine needed a bigger carb.

My local autozone, on two separate occasions, had a holley 600 behind the counter, new, in the box, for 200 dollars. (no electric choke)

That would be your best bet in my opinion. I LOVE a good carb debate thread, usually it involves lots of name calling and questions about ones parentage and ancestry...

An Edelbrock, is not usually a bolt on and go, they require a bit more work in the linkage area. As you had a Holley already, your linkage should be good to go.

I'd go with and Edelbrock 600. I have a Holley Street Avenger 670 on my 351C and an Edelbrock 600 (1406 electric choke) on my 302. I honesty prefer the throttle response and reliabilty of the Edelbrock. The Holley is good but seems more tempermental and more out of tune.

Great and overlooked carb. It is the great grand son of the Autolite 4100.

How much involved would get the throttle linkage to work with the edelbrock? My autozone has an square bore edelbrock 600 new for 260 but manual choke

I really like the Carter / Edelbrock carbs. My experience with them is that they are easy to tune, and once you get them set, you don't need to tinker with them again. I think if you are pretty knowledgeable with carbs, then Holley is great. My experience with them was that they needed to be tuned on a fairly regular basis. It seemed that I would get it running great and a month or two later I had the hood up to retune it. I understand that the backfiring isn't an issue anymore, but it sure used to be a pain in the ass and left a bad taste in my mouth.

Mind you, I'm not a carb wiz, and it's entirely possible that I never had that Holley set right to begin with. When I switched it out to a Carter, I never had issues with it not keeping a tune and I became a fan.

Performance wise, the Holley was great in the higher rpm's. It just kept wanting to go faster, but it was sluggish off the line and I could never get that fixed. The Carter was the opposite. Very punchy low end but lacked the power of the Holley at high speeds.

My opinion is if you are good with carbs and want the best possible performance, then get a Holley. If you aren't really good with carbs and prefer reliability and ease of use, then go with the Edelbrock. Of course to each his own, and my 2 cents is worth exactly that.

I'm not too concerned with performance right now as I am just getting it running right so I can move it around in and out garage so I can start working on all the mechanical stuff, brakes, etc. Performance will be last on my list of to do things. How difficult is it to swap a Holley set up to a edelbrock. As far as linkage goes.


Only linkage I have is throttle cable. Its a manual tranny so I don't need kickdown or whatnot.

I have one of those on a 351w in a old bronco and it works great.

hmm...Seems like a great deal! I'll look into it.

 

[Utard]

Mine had an autolite, and switching it was simple. I think I had to move the post that the throttle cable attached to and I was done. I can't remember what it took to switch from a Holley on my Camaro, but I don't remember it being crazy hard.

Another parts store has a new 600 holley for 300 but since my business has a national account with them they are willing to let it go for 255

Alrighty guys since tomorrow is my birthday the wife let me bite the bullet and purchase the new shiny holley on the parts shelf. Got it for 230 bucks with electric choke. Going to install this evening after work and see how it runs. I can't wait, come on 6 o'clock. Got tomorrow off too! new carb, hopefully a running car, and birthday cake. tomorrow gonna be a good day!
