I had a 1970 K5 back in the day, with the 350 and three on the floor. Bright yellow with the white top. Its long gone. Now I have an 84, with a 6.2 diesel and the Turbo Hydromatic 400. Lockers. The interior floor is all coated with bedliner. I run 33-12.50's on it.
That sounds like an ex military Blazer.
