I must admit that these are odd. But the casting number has not been played with. The guy I bought the parts from had these parts for over 30 years and he is the one that junked the car and knew the car from new. Small town here in NB. He is a car guy , says there were two 70z cars there. One orange? and the other Citrus green. The parts are from the orange one. I am no expert on the 70 Z cars, but I do recognize when something like a casting number is played with. All the other 492s I have or have had are the 3991492. And this number was used in 2.02 or 1.94 versions. Go figure. I have not checked the intake or carb numbers which I will do shortly and post..
