Just put a qjet in the lemans and im having trouble downshifting. The kickdown cable has a lot of slack in it and im thinking thats the issue. i looked up some youthtube videos and most of them show the kickdown cable connecting to the carb but mines connected to the pedal in the cab. whats the best way to run it. I need a hole in the firewall for some gauges so i see a +1 to running the kickdown off the carb. thoughts anyone?

Did you find instructions for adjusting the cable on your car? the factory shop manual is good for stuff like that...get a copy, usually you can find a used one on ebay for a reasonable price.
The way they work, it has to pull the cable all the way, at full throttle. So if there is some slack, it won't kick down. The last little bit of travel has more spring pressure, so it takes some playing to get a feel for the adjustment.
I would leave it where it is if the cable is in good condition. If you need to replace the cable (they crack and leak transmission fluid, among other issues) then you could connect it to the carb, but that requires the right bracket, etc.

what does it look like at the end that attaches to the pedal? this is a Y104 cable from rockauto.com, for ten bucks. Or get one from ebay for 75, not sure if it's the same, none of the pictures or descriptions are very helpful.
This is the correct cable for turbo 350 application on 1968 / 1969 / 1970 / 1971 / 1972 cutlass and 442 models. Kickdown cable goes from the transmission to the gas pedal assembly on the firewall. This is the factory cable that connects to the gas pedal on 1968-72 Cutlass & Skylark.

I love kickdown on automatic transmissions...it's worth setting it up, makes driving more fun.

though it may 'feel good' and be more convenient, i would
NEVER just floor it and let the trans kickdown at full throttle
in any automatic, but especially th350/th400/7004R.
though this may come off as preachy im not trying to be, just
trying to save fellow bangshifters the pain and COST of learning
the hard way, so bear with me...
one of my A.S.E.'s is in auto trans overhaul, ive had hundreds
of them torn down and rebuilt them, including my own full
manual reverse (with engine braking in all 3 gears.) th350 thats
in the white 461" vette.
in a forced full throttle downshift at speed, the clutches and steels
take a beating, and the drums and hubs do too.
in fact its the #1 reason that a 7004R breaks (besides the front pump
bushings failing) is the forced full throttle downshift when the sun shell
must instantly go from zero to 55mph or so, in a 3500lb+ car--
*SNAP* goes the sun gear clean off of the shell.
imagine a stick shift, floor it in 3rd THEN step on clutch and
downshift and pop the clutch..... thanks, ill pass.
id rather my trans live longer than 'think' for itself or
be simply easier to drive, but to each his own.
i pull a lever, then floor it. problem solved, and zero "lag" as well.

fatguyzinc thanks for the lesson in t350/400 and 700r4. I dont know that much about transmissions at all other than taking on out and puting a new or rebuilt one back in. I definitely will start dropping the lever when i give it the hammer. I would still like to have the kickdown cable at least for cruising around though. does daily driving with the kickdown cable cause a problem with these trannies??

it must suck to live in his world
I've never seen a TH350 fail because someone used the kickdown feature.
700s fail for lots of reasons, though.

not today, not tomorrow, but maybe the trans gets 8yrs instead of 15....
