Mr. Mike !
How's it goin' , bradah ? I hope that you're well .
Looks like a cool project ! I like the scale , 1970-issue Ca plate ( the "A" = 1970 issue ) .
I know what you mean about the -correct- colour for the '68 383 HP ; something tells me it's -- in this application , the 300 hp "A" Body application -- Chrysler Turquoise , just like its big brother 440 HP of the same year ; the "383 MAGNUM" pie tin has a red background , iirc ...
But , then again , it IS a custom ( albeit , a mild custom ), so who's to say that the motor wasn't repainted ?
Granted , there's a slim chance of that , as most closed-hood customs had completely stock motors .
Do It To It !
