Owned 2 original, #s, St.Louis '69 RRs with A/C. Turquoise 330-horse, RR pie tin, dual snorkels. Every original #s '69 RR with A/C, regardless of trans, that I researched at the time had the turquoise 330 motor, not the orange 335. Every non-A/C '69 383 I've seen, and I mean hundreds, was the orange 335. The small unsilenced air cleaner was a orange/335 setup, and the dual snorkel was for turquoise/330 motors. Carter carbs on every original '69 RR 383 I've seen, though different model #s depending on trans, A/C, Calif & high altitude (Denver for example). Calif & high-altitude carbs had one central mixture screw. The RR pie tin fits both air cleaners, as did the other pie tins. Magnum was the Dodge marketing name, as previously stated, and would not be found on a Plymouth except by error.
For what it's worth, I've found that some '68s & '69s ran stronger than others, and not necessarily related to the 330/335 rating. For example, my A/C car was stronger than one of my non-A/C cars, and except for the A/C, seats & color they were basically identical. The 335 car "should" have been quicker, but wasn't. My St.Louis-built '68 was quicker & more responsive than my L.A.-built '68 car, too.

I'm wanting to think that the A/C cars had one with a smaller cam, to help with torque to spin the compressor. That would account for the slightly smaller HP rating.

I don't think it was listed as 330 either in the RR, even if it were different. The marketing numbers staed the same.

I have a 69 bee with AC and the 899 engine. The engine is turquoise and it came with a 383 four barrel pie tin vs. the 383 magnum one. The block is not stamped HP. Also the carb was a Holley and not a Carter from the factory. It also has a different transmission as well at least by part number to the non ac cars.

I just sold a very origanal 69 Coronet 500, 383HP auto with A/C. It is a numbers matching car, the engine is turquos, and is stamped HP. From what I have found is that the A/C and non A/C engines have the same cam, just a differant distributors, something about the advance curve. A simple look through a factory parts book shows (1) cam number for HP engines, and lots of choices for carbs, and distributors. I have a friend who bought a 70 Challenger 383hp A/C new and still has it. It always has been a dog, I talked him into changing the distributor and wow!! the car is alive and has never run stronger.

Technically the 383HP wasn't available in the '69 Coronet 500.

... so besides a "HP" stamp, what evidence do you have to support that claim?

B'cast sheet and or Lynch Rd. fender tag numbers?

So is the 899 383 stamped HP or not?

Well I can tell you my 899 engine is not. Numbers matching and I bought the car from the original owner. Engine assy date is stamped 12 2

The spec ad for the 330 hp vs 335 hp 383 engine shows a 200 rpm difference; 330 @ 5000 rpm vs 335 @ 5200 with the same torque but again the 330 hp engine has the max torque 425 lb/ft @ 3200 rpm and the 335 hp's max torque is 425 lb/ft @ 3400 rpm.


It also reads the 335 hp engine has a "high lift, high performance camshaft and a windage tray", where the 330 hp engine lists a "standard camshaft" and no mention of a windage tray. I also thought the 383 HP engine got a different intake manifold from the 440 HP engine?
