Sorry, I tried searching for this as I'm sure this has been tackled before, but I couldn't find anything so guessing I'm just searching for the wrong thing.

What do people usually do on third gen camaros when the put Holley carbs on them? I'm putting a Holley Street Avenger on mine right now, and I think for now I'm just going to use a bolt, couple washers, and a few nuts to rig something up, but I'm worried about vibration eventually causing problems with that setup. It will just be something to get me up and running for now.

Are there adapters premade for this application, or do people end up changing out their entire throttle cable?

Thanks!

 

Holley makes the throttle cable "Stud" for our cars. Also if you have a TH700R4 you need the geometry adapter for the TV cable as well.

 

Thanks, is this what you are referring to?

If it is, why is it so long? Also I'd worry about vibrations with that thing to, what if vibrations causes the nut to back off and my throttle cable slips off when I'm trying to merge onto the interstate! lol, I know worse case scenario and probably won't happen.

Oh and I've got a T56 in my car so no TV cable.

Thanks,
although I don't see how that thing is supposed to work. Is the hex head bigger than it looks in the picture and you just tighten it in the middle of the large hole on the carb?

This is what I rigged up last night, and I think this would work just as well if not better than that thing, other than not having a spot to put the cruise (which hasn't been working in my car for 3 years anyway).



It's a little difficult to see cause it's blurry (phone pick in the dark lol), but it's just two washers tightened down over the hole, and then two nuts tightened on the outside to keep one from backing off. Leaving the throttle cable itself a little wiggle room and able to rotate on the bolt.

 

The one you posted is for both the throttle cable and cruise control but I'm not sure if that would work for third gens because I don't know what the shaft sizes are on that stud. But to answer your question, the stud has a lock washer with it and with that installed between the throttle lever and nut it will keep the nut from backing off. I haven't had one back off since I have been messing with cars back in 1984. Still you can add a little blue Loctite to the threads as an added touch if you are still leery of it.

five7kid has one choice and I believe this would work too

It doesn't go through the large hole. See attached picture for the stud location.

 

Ah, I see. Hrmm, I might just try to stay with my setup then and see if it causes any problem. To use that hole would move the throttle cable back 1/2 to 3/4 an inch, I'd be worried about it giving me noticeable slack at the top of the gas peddle. When I first put it on I had it pulled to the back of the large hole and thought I noticed it a little, so pushed it toward the front side of the large hole. It also wasn't quite reaching full throttle when pressing the gas peddle all the way down. Even where it is now it's not quite reaching full throttle, but only by a tiny amount now (like maybe 1/8th of an inch more travel available), so I think it will be ok.

I might see about getting a locking nut to put on it just to be sure it's not going to back off.

 

I have the same throttle bracket and I have mine in that location. The only thing with the bracket being that close is not opening the throttle all the way. Mine did but things could be different with yours like thicker carpet, cable length.... Just this year I cut 1/2" out of my bracket, welded it back together and now my cruise control lines up correctly.

 

If the throttle doesn't open all the way, it's a simple operation to remove the pedal, bend the metal bar so there's more bend in it, and reinstall. The extra bend will pull the cable farther back so there is less slack in it.

LS1 swappers do this all the time. It doesn't hurt the accelerator pedal, and is effective.

 

I might look into getting another throttle bracket to see if that helps some.

I am actually having one other problem, gonna post about it here to see if anyone has some ideas even though it's only somewhat related.

My intake, if you can't tell from the above pic is an Edelbrock RPM Performer (7204 if I remember the number correctly). On the passenger side of the carb, the choke adjustment screw is hitting the intake, barely.

I used a dremel and ground down a little on the intake, scared to go to far cause I don't want to grind through the intake wall lol. But it's only clearing because I screwed in the choke adjustment screw some. This however is causing the car to idle at 2200 RPM when the choke is on.

Any ideas on how to work around this?

The only two things I've thought of is trying to turn the choke a little to see if I can get it to unwind slightly there and idle down, or to use an unnecessary adapter plate to lift the entire carb up a little. The problem with lifting the carb up a little is with my factory hood and the rpm performer intake, I'm already barely clearing with a 2 inch open air filter. I eventually want to buy a ZL1 style hood, which will give me plenty of clearance (another 2 to 3 inches due to the small cowl in that hood), but that is another 450 dollars + painting costs that I don't want to spend right now.

EDIT:
five7kid, you just posted while I was typing this post. You mean the bar the gas pedal is attached to, moving the pedal closer to the seat inside the car? Or is there a different bar you are referring to?

 

I have the RPM Air-Gap and I don't have that problem with my choke. You can try an loosen the bolts on the carb flange and push the carb to the passenger side a little and tighten the bolts back down. This might give you the extra little clearance you need. Once the linkages are free to move you can then adjust the high idle screw for the proper RPM's.

As to you questions in your edit, Yes that metal bar and yes bend it up/out closer to the seat.

Holley has a throttle bracket that bolts onto the carb's base that will work as well.
