The only other color that I really liked was a darker blue. Photo attached. I have no idea what years and what motor it was used on, but it looks great! In the end though I decided on the light gray because I think it just looks clean and will brighten up the engine bay.
The blue colored engines started with the 1953 Powerglide equipped passenger cars and stayed a passenger car engine color. It was called the Blue Flame Six.
