I am beginning a build on my 79 Buick Century sport coupe. She has a Pontiac 301 and 3 speed transmission. I am going to install a 1967 gs400 .030 over with a th350 and a 3.08 posi rear. Will upgrade interior as this was a quick poor dye job. I will add a turbo sport hood and maybe some 15x7 buick factory sport wheels.
