I haven't had vacuum boosters on my vehicles for a while now. I think my GTO had it from the center carb port though.


This makes me think your vacuum is from your intake manifold and not the carb. Is this right? If so, then there are vacuum ports in the edelbrock intake that you can just buy a fitting from the local hardware store (ACE or TrueValue type store usually has it...Bigger box stores may not). They're usually cheaper than the autoparts stores too. I believe the edelbrock is 1/8" NPT. You'll want to verify to make sure.

I'll look on my photobucket see if I have a picture but if not I'll take a picture tonight for you. On the q-jet there was a how they described it in the video was a vacuum port for power brakes in which i have.

About vacuum ports I do have some on my intake manifold actually on top of my thermostat are my other vacuum ports I know one is for me to bypass the original air equipment so I could have the headers and another is supposed to be a transmission vacuum does that sound right? And then the PCV valve too.

Awesome I found a picture! when you look at the picture duane in the right lower corner you'll see a bolt sticking out that's what the brake boosters line was connected to. I tried and tried to get it off it just wasn't budging at all maybe I'll give it a go at it tonight, I could always use my impact gun I suppose? Here's the picture though.

So your vacuum source before was the carb? Edelbrock's brake vacuum port is the large port in the center of the carb, if I'm not mistaken. No fitting required. Just plug a vacuum hose to it and the brake booster. I'm fairly certain this is how my GTO was done prior to installing the Hydroboost system.

As for removing that fitting from the Q-jet... be VERY careful if you choose to use the impact gun. It might break the carb body... I've seen it happen. Just a word of warning.

[77ChevySharkBite]

That's correct that same bolt is where I loosened my brake like hose from. Does that make sense?

If you go to the link, the 3rd picture down on the left side is the port that I'm talking about just making sure were on the same page with it.

http://www.spiderautomotive.com/edelbrock1406.html

Yeah, I mean I tried taking it off with my regular wrench and it wouldn't budge maybe I'll try a socket the torque, and use the impact gun as a last resort.

[knomadd]

Now I'm on the same page. I've got a 1405 on my GTO and the 1406 on the C-10. I've got a cap on the large center port in the front of the carb on my GTO now. I'm fairly certain that's what my brake booster was connected to. My C-10 on the other hand has my valve cover PCV valve connected to that large center front port (all connections for PCV are in the intake from the factory on my GTO).

I don't have a good picture of it, but I believe I can see the vacuum port on the back of the 1406 connected to the old vacuum booster before I changed over to the hydroboost brake booster. With that said, try squirting some WD40 on that fitting and letting it sit for a while before you resort to the impact gun. Or, find out what size and type of threads that port is and go buy a new fitting.

[77ChevySharkBite]

Okay glad we're seeing eye to eye now yeah I have some knock off wd-40 but I'll spray a good amount let it soak for a while also someone had suggested for me to put it back on the original intake to try and get some leverage so going to try that too. Hopefully I'll be able to get it off tonight get a step closer to it being installed

Get a new fitting for the new carb and just run a hose to the brakebooster. You can get one pretty cheaply at the hardware store.

Yeah, I was going to try and see if I could break it loose last night but didn't get home till late and I just wanted to sleep. Might try to give it a go tonight, if I just can't get it loose I'm just going to go get one like everyone has suggested from a hardware store.

the original throttle braket wont line up with the edelbrocks bolt holes? thats strange, thought they had both bolt paterns on the intake. could be wrong though, if you have the sqaure bore style intake, then that wont work. the spread intake bores were more universal.

it lines up fine but there's like a nipple that part of it wont go over to clamp it together to make sure it doesn't move and then the original is to big my only other suggestion would be to take a tiny drill bit and make it a little bit bigger.

did this kit include the throttle bracket? it should just stand on the a couple bolt holes on the back of the intake.. oh and i did notice you do have a brake booster hole in behind the carb pad.. however its a small one

[chevybuilder18]

since your carb is wide the qauds throttle bracket wont be able to stretch to where the thottle stirrups are on the carb. heres the design thats suppose to bolt to your intake, so your throttle can be adjusted and center with the carbs stirrups.

No it didn't include a throttle bracket I have a friends dad who has a 76, same motor and everything same carb, and same intake he doesn't have it in the bracket it sits just fine it's all about that like nipple fitting that isn't working right so that's my biggest issue right now.

Yeah I see what you mean but i think that's if you keep the stock intake being I got rid of mine it got rid of some unnecessary items to clean it up.

Alright so I did what knomadd had suggested sprayed some wd-40 and ta da! just one good turn with a socket and it was loose! So got the brakes connected now so getting closer to start up.

I'm one more step closer to it being installed now my question is the original throttle linkage bolt wont fit in the hole on the carb but the new one they sent won't fit in the old clip so if I just ran the the new bolt and tightened it down (talking about the throttle linkage) would I be fine running it that way?

Hmm... Guess I haven't subscribed to this thread yet. I like the truck man.

Over use of "Bro" flag..lol. Did you figure out the throttle yet Korwin?

Yeah I got the throttle figured out Scott, all that's left to do is fuel lines, electric choke wire, do all the vacuum lines and then crank it over get the timing done correctly then done.

[77ChevySharkBite]

So tell me if I'm the only one with this problem here getting really discouraged with how long this has taken to do a simple swap, last night put on the throttle cable bracket well what has happened is it kinks the throttle cable cause the pedal to be hard to push down. Now tell me what my solutions are? Because we took rough measurements and the intake and carb only sit back about 1" further than the original and that's what is causing this whole problem so any ideas fellas? Or do I just need to bite the bullet and go buy a new cable?

[knomadd]

What throttle bracket are you using? You may need to change that instead of your cable. It might be worth a shot if you can find something at a local parts store. Or there are cheap online options like this: http://www.summitracing.com/parts/spe-24283/overview/

[77ChevySharkBite]

I'm just using everything that came with the Edelbrock carb, didn't buy anything else.

I'm sorry Duane I'm using the stock bracket from the q-jet.

[knomadd]

Does your bracket allow the connection to the carb work properly or is the angle off? Where is the cable kinked? Is it near the firewall, carb, or in the middle? Got a picture?
