TV Cable Question

[Nick88]

Whats up guys I have a 1988 TBI 350 with a 700r4. I decided to just order a tbi spacer just to see if it really did anything as I know many people have had luck with carb spacers. My question is do I need to spacer up the tv/accel cable bracket upwards aswell to keep the same geometry, or can I just adjust the tv cable and the accelerator cable to be a little longer. Any help is appreciated!

My advice is to not bother with the TB spacer. When I was young and dumb I added a TB spacer to my TBI truck and I didn’t know anything about the TV cable at all. About 150 miles later I could feel no engine HP increase and my trans was toasted due to incorrect TV cable geometry and wrong tension. I’m sure you could modify the bracket and tension to make it work but is it worth the risk and hassle for very little potential gain? I ended up removing the spacer, having the trans rebuilt and never had an issue after that.
