I have read that the automatic 289 Cobras had 6 bolt engines while all of the manual transmission small block cars got 5 bolt engines. If that is true, were the 6 bolt engines painted blue, or black? On the subject of painting, I am aware that the valve covers were either chrome, or the aluminum versions (talking street cars here), but what exactly was painted on the engine? Was the timing cover and water pump painted? The photos I have seen suggest that is true, but they are not really clear. Thanks!
