It also appears that you couldn’t get A/C with the manual transmission.

I see that for the GTX but not the Roadrunner.

Here's where you don't get the Roadrunner engine in a Roadrunner with AC.

Anyone know the specs on the factory Holley used on '71 383 Road Runner (part number and CFM)?

Guys, remind me, what is the difference between a 330 Hp 383 and a 335 HP 383.

Had a 330 horse engine in a 70 Challenger and it didn't come close to performing like a 335! Only thing on it was a Accel dual point that wasn't original....car was bought from the original owner in 1980.

That chart is full of 1969 Only part numbers. There are no 1970 carbs listed.

And let’s keep this post all about 1969 for simplicity sake. Other years had many changes that just don’t apply here. They changed things every year or two since the start of BIg blocks in 1958.

All 1969 383-4bbl b-bodies: roadrunners super bees coronets and Chargers had HP exhaust manifolds. Even station wagons and 4 doors.

Apparently they did the same thing for the 70 Challengers because the one I owned had the HP manifolds....even had the dampers on the valve springs. Non RT flat hood car with dual exhaust with turn downs at the back.

How in THEE hell could a Road Runner not have the 'Road Runner' engine.

Marketing was worried that it wouldn't be as driveable. The standard 383 had the same torque but it came in 200 rpm. earlier so they used it for A/C cars.
 
My experience here is with SuperBee's, but I think information would also apply to RoadRunners. The orange 335 h.p. 383's got a Carter AVS, but the turquoise 330 h.p. 383's got a Holley. A/C-equipped 'Bee's got the 330 h.p. motor with a Holley. Regular Coronets mostly got the turquoise 330 h.p. motor with a Holley. If someone knew what he was doing, the orange 335 h.p. motor could be special ordered in a regular Coronet. I once found the remains of what was almost a SuperBee convertible in a local junkyard. Coronet 500 convertible, with bench seat, 4-speed, and orange 335 h.p. 383 with high performance exhaust manifolds. Difference between the two engines was the camshaft and addition of windage tray to orange engines. 335 h.p. engines with TorqueFlight also got higher stall converters. All 1968-1970 big block engines got "906" heads, whether high performance or not.

The parts manual says that the 4-speed gets the other Carter. That auto looks like it got the Holley sometimes.

Let’s keep this to topic 1969’s only. Other years don’t matter.

The 1969 charger/Coronet/Dart service manual doesn’t show any Holley 4 bbl carbs. That parts book page above shows the 4440 for RWPDC. Possible a typo? The Galen white book shows the same. It’s the only Holley they show for a b body.

I’ve never seen a 1969 roadrunner/Bee with a Holley carb. I’ve only seen them on low horsepower 440 only in full size cars.

I don’t think it’s plant related. The St. Louis plant made a lot of cars and we see plenty of them on the west coast. LA didn’t make as many cars as other plants.

do you have a broadcast sheet for your car? What is the carb Code? We need a registry to look at their files and see if any have any b bodies with a Holley code #31.

I do not have the build sheet, I wish! I pulled the seat last week with much dismay.
 
Most info is in the FSM but no where near all. Especially for many of the less common parts combinations. But a very valuable source of info.

Just an FYI they stashed the build sheets in different places sometimes. Check behind and under both pieces of the rear seat, under both front seats if you have buckets, or under the front seat if you have a bench, they also put them over the glove box liner sometimes. There maybe some other places to look, others on here may give you some other hiding places. Can't hurt to check maybe you'll luck out.
