'78 Kickdown Cable
Hi,
Working on a '78 Indy Anniversary with L48. After 240K miles, the mtr was rebuild, but the owner is not satisfied with it's performance. Everthing exterally appears to be completely stock in appearance.
Noticed that the secondaries are not opening all the way, due to the kickdown cable restraining full linkage movement. So there's the reason for the disappointing performance.
Found out that the trans was rebuild prior to having the engine pulled for it's rebuild.
The bracket holding the kickdown cable is seperate from the accelerator cable held in-place by the two rear intake bolts. That appears to be correct, but could someone who owns a similar year with base engine/auto verify?
If the bracket location is correct the remaining question would be either whether his original trans was rebuild with the correct length kickdown cable or a totally different unit installed with a different length kickdown cable? This is to be verified. Could someone point me to the area to check for id numbers on the trans case?
Thanks for any responses.

Cable length can be adjusted at the bracket

engine assembly top driver's side
Could someone point me to the area to check for id numbers on the trans case? .
The eight-digit VIN derivative is stamped on the driver’s side, toward the front, bottom edge of the transmission just behind the rubber boot that protects the shift linkage. Often, the broadcast code 5TL, stamped in black ink can be seen on the passenger side. The last five digits of the VIN derivative will match the VIN on the driver's side windshield post.
The production code is stamped on the passenger side in a vertical boss with a six-character code. The image shows how to interpret the numbers.
Hope this helps.

Thank you for your help.
Did not think the TH350 cable was adjustable like the way the 2004r and 700 trans were? Suppose there is a tab on the carb side of the cable that gets lifted up?
hunt4cleanair, the picture did not really show the details for the cable set-up, but it clearly showed that the alternator plug is at the 12 oclock position. Another problem under the hood of this Corvette is that the alternator bearings are fried. Seems that sometime prior to the mtr swap the original alternator was replaced, so there is no sense rebuilding the one that's presently there

Thanks for your help hunt4cleanair. The pic actually shows that the bracket for the trans cable is correct compared to what I'm working on. I'll be by the car again this weekend, as I have to pull the alternator and I'll have another look at that cable about whether it's adjustable. Just don't recall them being that way, at least not the factory installed kickdown cables.
