5.3 swap in a 76 k5 blazer

[bios]

I'm going to perform a 5.3 swap, I pretty much found out all the information I need and I had a question for anyone that has performed the swap....

I am putting a 01' 5.3 vortec in and I wanted to keep my freshly rebuilt TH350/NP205 combo and I was wondering if anyone had any experience doing this.

Does anyone know where I can get an adapter or straight up new throttle cable and kick down cable to attach it to the 5.3 intake? That's pretty much the only thing I have a question about because I wanted to use my stock pedal and transmission configuration.

Any help is appreciated, thanks in advance.
