    I tried to search for the answer but apparently I can't put together a working combination of search terms, because I didnt' find what I was looking for.

    What would be needed to put a 700r4 behind a tbi 454?? is there a factory setup for the the TV cable that is out there somewhere???

    thanks for the help, in advance. :bow:

    the TBI on a 454 is not set up for a TV cable off of the 700R-4 it wont work and the factory never put a 700 behind a 454 thats why the TV cable issue is their

    I figured as much... at 3:30am I was apparently thinking there were still 454 cars being made! duuuurrr

    I am going to assume for the moment that there is an aftermarket solution.

    What i'm going to do is remove the side linkage piece off my 350 TBI unit and put it on the 454 TBI unit, problem solved. Yes, you will need to grind and weld but much easier than trying to fab up some kind of bolt on bracket or somethig and i'm sure it will take less time as well. :thumb:

    That's not a bad idea. Probably pretty close... just dont' want to toast a 700r4.

    The throttle shaft is in the exact same location as the 350 is so it will work perfectly.

    then what do you need to grind/weld? I haven't compared the 2 yet.

    The peice of linkage that your throttle cable attaches to is either welded or crimped onto the throttle shaft. Grind off the weld or crimp on both units then swap the 350 linkage plate onto the 454 TBI and weld it on. :thumb:

    Sounds like a good fix for this problem.

    I guess I'll find out soon enough- I just scored a complete BBC TBI setup and a complete BBC serpentine setup.
    Now I just need to bolt the 454 and other new parts into my tow rig Burban...

    DUUUUR now that one should have been obvious to me. I was thinking "grind something to fit" not "grind something to remove it" !! :doah:


    THANK YOU for your help.

    I've toasted 2 700's behind my 454. I'm going to a th400.

    yeah, jury's still out here as to whether a 700r4 can be built burly enough for my purposes..... I may just stick w/the 400.

    Watson's having good luck with a 700R4 behind a BBC...but it is a trail rig only.

    There's no doubt in my mind that a 700r4 can be built strong enough to take the grunt of a healthy BBC, if you have the coin. I don't. I think it's great that someone has found success with that combo. Unfortunately, I have not. I'll admit that both of mine came out of wrecked Suburbans. If I had a 350 or a 400 in mine, it would be a different story, I'm sure. Oh, well. Wifey wants the big block. Gotta keep mama happy. After all, she bought it for me.

    you are the smartest man in this thread!

    I'm tearing apart my wife's DD to swap parts into the trail truck. I am therefore, the dumbest person in this thread.

    Quit snickering. I can admit it! hahahahah
