I tried my factory TBI and there is no way it will work and an LT1 car cable is the same length. There just happened to have been a 1990 corvette outside so I went and looked at it and found that the cable hooks up perfect but is a little too long. I cut the end of the cable and put a cable stop on it and it worked while putting the finishing touches on my car. I drove the car for the first time and the next day, after a few hours of showing people, I started up a road and the cable stop came off. I know if I use a cable stop again it will just come off again like today. I have searched and most people say the factory TPI cable works with "a little modification" but they don't tell what. How did you guys do yours? Any pics or desciptions?

 

get a tpi cable from a third gen. it will work great, thats what i did.

 

I got a cable for a like 91 or 92 tpi car. I had to file down the throttle cable bracket a little bit to get the cable to fit right, but now it's fine.

 

I got the 92 tpi cable as well

 

I'm using one from an LT1 car.

 

92 tpi, had to cut away a little bit of the plastic on it to fit the LT1 bracket, basically i made the plasitc part of the tpi cable look like the LT1 cable, notched it out a little bit.

 

How? The one I tried for the 93 barely reached the bracket and there was no way it would reach the throttle.

I got one for a 91' TPI car an it worked perfect. Thanks for the help.

 

thats odd, my LT1 cable had too much slack, from a 95.

 

I'm running a set of 4th gen pedals, maybe that makes the difference.

 

Im running a 93 LT1 cable with my stock 3rd gen pedals. It hooks up easy, but the cable is too long. If I floor the pedal, I only get about 60% throttle at the throttle body.

I just bought a 92 TPI cable... We will see if that fixes my problem.

 

it will

 

I ended up getting a '92 TPI cable, the LT1 cable worked when it was in my '86 but in the '87 it was different *shrug*

 

I went a bit different and used a lokar stainless braided throttle cable.. I believe it is the TPI cable that they offer.. more expensive but if you want that style pm me and I will dig up the part number.
