My carb recently went out, and I'm thinking about going bigger, so when I start modding I'll already have it on the car. My car is completely stock, and i was thinking about going with something like a 570cfm or 600. But if I adjust the carburetor right, will my car run rich, or should it be alright, considering it isn't a really big carburetor? I'm completely new at carb's and thats why I'm looking for some advice.

 

I would go witha 650 with mechanical secondary and if its a DD electric choke for those cold days

 

get a 600 or 650, i am currently running a 650 mechanical secondary like what he sai up there.^

 

For my 1985 GT, i have a Holley model 4180(electric choke) and it flows 650 cfm's. Motor is all stock and so far I am happy with the carb.

 

What do you mean your carb went out??? And if what you had served it's purposes, going to a bigger carb isnt going to do much for you... in reality, what ever you choose to do, you need a dyno with gas analysis... a proper tune and jetting is the solution... not just simply bolting on a bigger carb....

 

As in, it's completely shot, it's done for. I just wanted to know if adding a bigger carb to a stock motor would affect it negatively in anyway, because there is no use in buying just a replacement if I was just going to get a bigger one a couple months from now. Yes, I was going to adjust and tune the carb after I put it on...I learned my lesson after someone in front of my work just put on a new carb that day...but then his car caught fire[8D]

 

a bigger carb on your engine will flood it

 

Ok, I got two different answers. One says it'll run fine, the other says it'll flood. I want to know, because I don't want to end up buying two carburetor's in like a 3 month span if I can just buy one now. But I also don't want to buy one and let my car run like garbage for those 3 or so months.

 

You need to fit your carb with your engine.... putting an 850, for example, on an engine that doesnt need it, an all you will do is wash your cylinder walls down with gas, which is not a good thing... if you had no problems in the past, and for some reason you need to replace the carb (and not rebuild it) then replace it with what you presently have....
