1968 and 1969 HP383 had AVS carbs, Mopar switch the 383 HP to Holleys in 1970./71. No Thermobogs on any 383 from the factory scope
Is your car a non CA car? If so it probably has a different part number than the CA cars had, same thing with automatics having a different carb#s than the 4 speed motors.
As far as engine colors in A body I'm not sure, I think most of the HP 383 where street hemi orange but maybe not confused
I remember seeing a early 383 1968 Road runner 4 speed car with the Turqoise colored motor shruggy
