Wow, that really is a dark gray! I definitely would not want to use that color. Like Rusty Heaps said, if I’m not showing it or trying to be 100% authentic then any color I choose will be just fine. The Bill Hirsch gray looks pretty nice and has good reviews from ‘bolters who have used it. 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.
