I have a 1980 K-5 Blazer with a tired 350 small block and 350 turbo trans. I just recevied a good running 454 big block and turbo 400 trans out of a 2x 1974 Suburan. I curently run a np205 transfer case behind my turbo 350 does anyone know if it will mount up or do I have to change input shaft to run the 400. And does anybody know if I will run in to problems with the install of the 454. You can send to me at email@example.com thank you.
