From my understanding, the 383 Magnum (or Commando) engines were only supposed to show up in SuperBees and RoadRunners in 1969, without A/C. A friend of mine has a factory A/C '69 'Bee and it has the turquoise 330 h.p. motor. I believe the E63 code covered both these engines. Does your engine have a Holley carb, or a Carter AVS? The 330 h.p. motor came with a Holley, while the Magnum had the AVS. With you being the original owner, knowing the history of your car from Day 1, if the engine has always been orange, I would say that it is a 335 h.p. piece.
I bought a new 1969 SuperBee with the 335 h.p. orange motor and AVS carb. My car had the RamAir hood, so did not have the small round air cleaner with a pie pan. At the same time, an acquaintance had a new 1969 Coronet 500. It had the turquoise 330 h.p. engine with a Holley. At the time, I felt like I got cheated, because all the hot rod magazines made out that a Holley was the ultimate carb. I remember that my Super Bee sounded a lot more " rumpety " than the other guy's 500, so definitely a different cam. A while ago, I discovered a 1969 Coronet 500 convertible in a local junkyard up here. It had the remains of an orange 383 in it with a stick shift bellhousing ( the 4-speed was missing ). I harvested the the HP exhaust manifolds off it for my project. I have learned to never say " Never " with Mopars. Although printed literature says the orange 335/383 was a special motor available only in SB and RR, there must have been a way to order it in other B-bodies as well. Does anyone know of Belvederes or Satellites with factory installed orange 383 with AVS?
