Why do I see so many Chevy Orange 305 V6's in photos here and on the internet?
Not concerned with originality, "thought it was a ch##y", owner preference...
Did owners paint them when rebuild?
probably, I would have...but I'd do the red.
Are some years orange?
I think the last few years may have been; I think BigBlockV6 mentioned that fact.
Is it the camera?
sometimes those cameras and light conspire to produce that which we did not intend
Better the red instead...
