64 Barracuda slow going.

Also I went with a hydraulic lifter and cam combo so that my dad wouldnt need to worry about valve lash adjustments. Unfortunately two days after I got it back and was enjoying the break in period the car died afyer I parked and wouldnt start. I was freaking out since I couldnt find the solution easily. Im not versed in electrical work at all so I started a thread on my favorite forum about my problem and immediately got back alot of super helpful advice. I cant say enough about all the great guys and wonderful help ive gotten on FABO so far and it was thanks to you all and especially 67dart273 that I was able to track the problem down to the NSS ground causing my dead car. I drove it again today to work and am soooo thrilled.
Now back to the shifting problem. It appears that the new carb is causing the shift linkage to not kick down when I mash the pedal to the floor. I called the shop that did the RnR on the motor and they confirmed that it needs to be lengthened a little 1/4" to 1/2" to shift up at a higher rpm than it does now and for the kick down to work. I tried to unthread the end of the linkage to adust it but it was only on tje last 2 threads already. Does anyone know where I can get one of these but much longer, or a spacer? If not im sure ill come up with something. I did some searching about the linkage and it appears that if its too short the kickdown wont work and itll upshift too soon and maybe even cause slippage or damage so im going to fix and adjust this asap. But otherwise im super happy and cant wait to tackle the headliner next after I get the shifting sorted.
