Here'a tidbit you can pass on to your grandkids. ALL the 283's I've ever had, or seen, were the funky orange/red color. ALL the 327's I've ever had, or seen, were what is popularly called 'Chevy orange'. This, of course depends on whether they were repainted and painted the correct color, which in my case, they had never been repainted. The last 283 I can recall was in a 68 Chevy 1/2 ton p/u. And it was orange/red. Incidentally, I had to show a guy this particular p/u motor, because we had discussed this very same issue one night at work. Neither one of us, at that time, was a genius.
