I stumbled upon this old thread. sixtiesmuscle had his info correct. I have an old advertisement somewhere in my stuff which addresses the color question.

Nickey offered a "Choose your engine color" option, for their conversions. Obviously Yellow isn't for everyone, but it did make the engine stand out.

I painted the engine in my '69 Camaro Yellow, back in 1980, due to the Nickey Legend. Just thought it was cool to do since Nickey had also done it.

When I had the 2002 Nickey Tribute ZL1 Phase III GMMG Camaro built, we had the engine and heads painted Yellow as one of the Nickey details.
