i asked a similar question a while ago-it`s a numbers r/t challenger 383 4 speed n code with no air and it is an la built car. under the orange paint is blue paint and i wondered why the blue paint is there. i believe the engine should be orange but until we strip the engine one day i won`t know for sure. it`s a great running car so it won`t be any time soon.
you can see in the pic of the vin pad the blue is there-was it rebuilt and painted blue earlier in it`s life-most probably-it just seems strange someone would do that.
all the best
frank.
