curse those damn stubbern SOB's at holley. They just have to do it their way. Its not a carburetor, why make it like one??? Why cant they just stamp out a second stock spec throttle shaft for the oem replacement tbi's to make them 'oem replacements'. The relations for the linkages are all different.

*sigh...* what are you guys with the holleys doing to get the linkages to hook up to the tbi in a sane maner? What kind of brackets are you using?

With the stock bracket, the throttle cable not only binds with the detent cable but the gas pedal doesnt even hit the floor at WOT like it did with the stock tbi, leaving teh cable to take all the force. I found this out the hard way when i floored it and the ball crimp on the end of the throttle cable by the gas pedal poped off, leaving me to idle back home.

It just seems like they want it not to work.

since its basicly a carb connection anyway, i would assume that a "universal" adjustable throttle linkage bracket would work.


what bracket are you using now?

stock tbi one. i was just looking at the edelbrock universal fully adjustable bracket. It has the same configuration as the stock one but each mount is fully adjustable. Ill give that a shot and see what happens.

heres a pic of it. The angles are a little different but it looks like it might work.

You wouldn't happen to have a part number for that would you?

Thanks

Oh, yea, probably should have asked if it worked too......

Thanks again!

havnt had a chance to order it yet... too buisy fixing everything else that keeps going wrong. You can find that, as well as many other brackets and linkages in either the jegs or summit online catalogues.

This is the kind braket that I'm using, but I think mine came from Edelbrock for their intake mainifolds.

Hey guys, found the part numbers on Jegs.

Check your local shop too, Automotive engineering in Tampa was 2.00 less, and thats not even counting shipping. Couldnt find a chrome one though

According to ups, the stuff i ordered arrived at my house so when i get home ill start working on it and post back about my restults. I thought about doing that as well but ill keep it as a last resort if i cant get the new adjustable bracket to work. I want to keep the tbi unmolested if possible.

well, i installed my locar universal fit cable. Like most universal fit parts, it didnt fit. I ended up just sticking the throttle shaft under the drill press and drilling out the connector and attaching the locar connector on the right side. Since i did it this way, i didnt need to use the edelbrock brackets. The only complaint i have is that the gas pedal is half way down instead of where it used to be when the throttle is closed. The throttle opens up all the way with the pedal to the floor but it seems to have alot less travel then it did before and its more sensitive. Oh well, ill jsut do burn outs whenever i step on the gas. Now all i have to do is get my 9-bolt back together and i might actually make it out of the neighborhood this time:lala:

Jsut got back in form mixing and matching parts of the stock throttle and the locar one and i couldnt be happier with the end result. The adjustable end of the locar with its cable in the stock cable housing works super smoooooth If i where to do it again, gutting the locar cable for its cable w/ ajustable linkages and taking the extra minute or so that it took to drill the throttle shaft would be the way to go.

Dimented,

I know this is an old post, but I just stumbled across it and noticed that you had a tbi that looks like mine does. The old style holley. Did you have to drill out the IAC yourself? And what exactly did you use for your throttle adaptor? I am working on getting this thing put in my car as soon as possible.

Thanks

Bill

The one I have had the IAC already machined into it. Your right about it being one of the older ones, circa 1993 to be precise. You could either run without it, which would work ok except for teh fact that youd have to step on the gas to start it, or you could see if maybe you could have a machinist drill, tap, and finish the area where the IAC mounts. Does it have all the passages, but no hole? Or is it jsut solid cast aluminum on that side?

As for the adapter, its one from holley, I wouldnt recommend using it, though, as the tbi sits off center.

Dimented,

Hey man what's up? Thanks for the quick response. Um about the TBI it has the place to drill out the IAC. Looks like it could work fine. Can you really run without a IAC? I never heard of that. I that it stabalized your idle. Oh well, thanks for the input man.

i guess this is answer to my post a week or so ago. i am mounting the 454 to howell bracket and the offset is 3/8 inch to front. lokar responded to use their TC 100U which is adjustable. they suggested fabbing a bracket? i will go with Edelbrock as you suggested for bracket. what about the cruise control? how will that need to be modified? no need for kickdown as manual. car in barn 5 miles away so no access to it for a another month.

I ended up mixing and matching parts from the locar cables and my stock ones since the stock cable housings fit much better then the locar ones did. The edelbrock one does have all the mount points in the stock configuration, and they are fully adjustable so even though I didnt use it it looked like it would have worked.

please clarifry for me. would you suggest i use GM truck cable and edelbrock adjustable bracket? i think you had an issue with GM cable end and holley TB fitting on shaft. was that the case? If so my GM truck cable will work with edelbrock bracket? also i neglected to mention Lokar will do a custom cruise cable for $80. my buddy says there are extensions for cruise avalilable for generic aftermarket cruise controls. car dealers used them to add cruise to non cruise cars when the fit was less than perfect.

Sorry for the confusion, If you get the edelbrock bracket you can probably use the truck cable, shoudl fit fine. If your using a holley unit, one thing you have to do is drill out the nipple that the end of the throttle cable mounts to and move it to the other side. This will help all the cables clear otherwise the throttle and tv cables cross and bind on eachother. A standard fitting for a carb will work for this. Most of what you need can be found at a performance shop or at summit. Thats pretty cool that locar makes custom fit stuff for the cruise control. A stock unit thats intended for a standard tbi system might also work. You really wont know texacly what needs to be done untill you get the 2 bbl tbi unit mounted up and see how it looks. I wish I could be of more help but Im not terribly familiar with how the corvettes are laid out.

thanks for the help. the vette cable comes in on passanger side. the 454 TB works off the driver side. it wont make any diff as the manifold is a single plane(however cruise is on passanger?). only issue may be cable lenght but cant see that as too much of issue. will compare GM truck to original vette on lenght. if close go for it if too far off call Lokar. trying to get all parts lined up for smooth install. hate waiting on parts. hate more when wrong ones sent.
