1970 just adds confusion - because of a new set of "rules" probably initiated by unhappy '69 A/C RR/SB owners who received turquoise 330hp engines

for 1970 it was simplified:
badged musclecars: Road Runner (RM), Super Bee (WM), 'cuda (BS), Challenger R/T (JS) & Charger (XH/XP) with 383 4bbl ALL received the HOLLEY equipped ORANGE 335hp 383HP engine

everything else:
Belvedere, Satellite, Coronet 440, Coronet 500, Barracuda, Gran Coupe, Challenger, Challenger SE, etc. with 383 4bbl received the CARTER equipped BLUE 330hp 383 engine

EXCEPT those with 383 4bbl & a manual 3 or 4-speed transmission, these received the HOLLEY equipped ORANGE 335hp 383HP engine
