65 235 Engine Color or maybe 66 250

[kizer]

I have a 65 LB Fleet and was trying to find out what the Engine was originally painted.

However I believe the 235 was replaced with a Chevelle 66' 250. I'm way up in the air to which color to go with depending on which was originally painted what. I still need to verify that the 250 is a 250, which I more than likely will do this winter when I tear the front end off to get down to the frame so I can prep it like I did my back half with POR15.

Anyways anybody have any info on what a:
1) 65 L6 235 would be
2) 66 L6 250 Chevelle would be

Heck worse case if I can figure out what a 66 would be. Any photos or links would be great so I can get an idea on how it was painted or what wasn't painted on the motor.

This is what I'm working with.
