hey stephen, i know exactly what color your talking about. im rebuilding my 292 right now and after powerwashing off all the grease and dirt, i found that mine too has a light green color. all ive ever heard from people is that 292's only come in two colors, chevy blue and chevy orange. my dad has a 75 sports van that has chevy orange straight from the factory. my guess is that in the late sixties and through out the seventies they started painting them orange. im trying to find out where i can find the appropriate color green as well. keep looking, ill post if i find the correct color but i really dont want to have to settle for anything else but original either. anyone else know about this green color?
