Tonight I was starting a tune up, the oil, etc. Well i was going to put on the performance air cleaner on the car that the guy threw in the deal with it. I went to put on the extention to the bolt that sits on the top of the carberator and my light slipped, which let it fall into the carb, the very bottom. So i take off the carb, get it out.

I had it all bolted back together and was getting ready to put the performance air cleaner on like an hour later and sure enough the the gas intake line is leaking right where it connects at the carberator. So I take it off and studied it. Turns out when i took the carb off, the bolt that tightens from the line to the one built onto the carb, well it came off with the line instead of staying on the carb. Well When I put it on again it either stripped or was already stripped. I tightened it pretty good before hand and figured it was good but it was leaky. I guess my facotry carb is now junk on this car. Ill have to get ahold of my buddy this week and have him give me a hand. Ive never taken off an intake and gasket before. I do have a 4 barrel carb though that i can put onto the car.

This really pissed me off though, anyone ever do something simliar as stupid as me. What gets me is i did this once before on another car when i was 19, and im 25 now. Was I supposed to hold the nut on the carb as i undid the bolt holding the line to it? because i didnt think much of it, and it came off easily? the return line didnt give me any problems? Could someone let me know, I feel really retarded right now.

 

Yes, you were supposed to hold the nut, but you're not the first to not hold it, nor the first to crossthread that fine threaded nut and strip it. Might email Holley for a fix. I think they sell something to fix the crossthreaded, stripped threads.

 

By "factory", I take it you have a Quadrajet. I can't tell you how many I've had with stripped out inlet fittings. The threads in the carb wear down over the years, from removing it to change the filter inside, and also from torquing the fitting back on too hard. But they do make a slightly oversize, self-thread cutting replacement fitting. You're not the first one to strip these out, it's pretty common, which is why there's a fix part on the market. Check your local parts store.

 

into that fixer part tomarrow, but good to know, and thing is there was no fuel filter in there either which makes me wonder was this thing nig rigged or something or what? Perhaps even JB welded. How about mods, is there a better carb I could stick on there instead of this one, or factory 4 barrel that might give me a bit more iimpph when going down the road and not sacrifce much for gas mileage considering im already not much higher then like 12 mpg lol.

Could you let me know what you think i should get for some performance? and help me pick out a proper fuel pump? Again I have a lot to learn and would need some help deciding. Id like to go with like a 600cfm carb though, quite a bit of imph wouldnt ya think?

 

Most people take those sintered bronze filters out of the inlets as they are so fine they plug easily. I always do, then put a quality inline filter ahead of the carb for better performance and easier maintenance.
It's hard to get good performance and HP gains, and also good mileage. Usually when someone tells me they want HP gains I figure they don't care about mileage. Once you get it running really great, your foot will hinder any mileage gains.
I'd need to know some particulars about engine specs before recommending a carb size and type. As for intakes; most aluminums will give better performance than stock cast iron because they are designed more for performance, and not for mileage. There are some that try to combine both, but you wont feel any difference over stock with one of them.
A good hi rise intake and carb will give you enough extra power to feel the difference. And if you can keep your foot out of it you'll probably get as good a mileage as you do now, or better.

 

car so I dont really care too much anyway. I just dont want to dip down like below 8 miles to a gallon in this beast or anything lol. So a high rise intake is the way to go i take it. As for the motor man, Well you responded plenty of times to my first hello post. The motor is as bone stocky is one gets, 0 has been done to it. it even had that bronze fuel filter piece in there still. It has the factory exhaust manifolds you name it. The exhaust is a single in and duel out flowmaster muffler. Very very little done on this 75K mile car. So what size carb would you go with then with that high rise intake? Like a 600, I believe thats the size my friend runs.

Here are some high risers duel planes

Ive never heard of the company, i dont know what advanced auto magazines offer accept they get there stuff the next day. whats with the huge difference in price? and what do you think on the 60cfm carb idea?

 

I wouldn't go with a high rise manifold if its a bone stock engine. A low rise like the performer or rpm would be the best with something like a 600 cfm 4 bbl carb. maybe even smaller than that unless you plan on doing other mods like full exhaust and a cam.

 

ll definitely have a cam in it down the road and ill be keeping all these stock parts so i have the original parts for the engine down the road. What are the differences between high rise and low rise? What would happen if i put a high rise in vs a low rise? I dont want to blow the motor up or anything.

 

For your intake manifold, I'm leaning towards the Edelbrock Air Gap. It's a good performing manifold, and it's design helps to keep engine heat away from the carb, which helps performance.
Other than the stripped inlet, which can be fixed, are you having any performance issues with the Quadrajet? If not, I'd leave it on. Q-jets can work very well, as long as they're working well. Basically, if your carb is working good now, I don't see you gaining anything by replacing it with an Edelbrock carb. Your wallet will be lighter though.

 

there wasnt anything wrong with it except its only a 2 barrel carb. I would think that upgrading to a 4 would be better right. I do have a factory 4 barrel though as well which was given to me from the previous owner. I really wouldnt see any performance gains your thinking? with a newer one
