305 vortec to 350 vortec
I did a 305 to 350 swap about 3 years ago. The 350 came out of a 97 GMC Yukon along with the computer. Just recently I decided to replaced my whole ac system which hasn't work in 8 years. Long story short. The truck runs great but for some reason the 350 computer will not run the AC but the 305 will. And yes I have tried a computer out of a 97 Chevy Silverado and same issues the compressor will not kick in. Runs fine with the 305 computer.
