Did the 1970 roadrunner come with a 440 engine option?

hieveryone I'm curious if the 1970 roadrunner was offered with the 440 engine option. I've been told it wasn't offered because thatad on superbird only But I feel like I've seen 440-6 70 roadrunners. So I'm sure some of youwith that mopar knowledge must know. I've been looking for a 70 440 roadrunner and haven't seen one so I'd like to know if not that way I can get myself a 383 and not search for something that doesn't exist. Thanks

440 Six Barrel was an option that year.
 
Agree. There were three choices: the base HP 383, the 440 6 barrel and the 426 Hemi.
WHOA, in 1969 I bought a new coronet rt w/ a 440/4 speed /dana 60 , My buddie bought a 1970 440/4 barrel/4 speed road runner the next yr, it had the air grabber
set up on it, w/ black hood treatment on it, had a dana 60 too.

440 4 barrel engines were certainly available in B-bodies, but the OP asked about a 1970 Road Runner. 1970 Road Runners were not available with a 440-4, so if your buddy bought one it was either modified or some kind of very unique build from Plymouth.

Wrong my friend, he bought it at Cox chrys. on 11th in Tulsa, brand new, he found out later it was very rare. After he traded it. I found out that a 1968 barracuda form S fastback I bought in Tulsa, new, was supposedly one of two made w/ a 330horse roadrunner engine in it, it was rated at 330 instead of 335 because of the drivers side exhaust manifold. There were exceptions to the rule on a lot of old mopars. They above statements are true, wheather ubelieve it ornot. The guy that bought the roadrunner was a Chrysler mechanic at the time he bought it, he is now a retired auto shop owner. If u want to call him, I could give you his name and number in a PM, but I doubt that he would like it.
 
VIN's don't lie.. So if it was a 440-4, it would be a U code and yes it may have been possible to get a special build, but standard ordering did not have a 440-4 as a standard order item..

I'm not trying to get into a pissing match with you, but I'll stand by my original quote in the earlier post. Certainly your buddy COULD have purchased a new 1970 Road Runner with a 440-4. However, if he did, it was not a routinely available car; perhaps as a Chrysler mechanic he was able to put in a special order. For most people, the available engines are shown below.

Clearly the burden of proof lies on the 70 440 roadrunner owner to prove with VIN number, fender tag or window sticker. Recollection from decades ago surely gets skewed.
 
If it was a 70 RR (not GTX) with a 440 4bbl, that would be one rare bird!
 
70 Superbird was available with 440-4.

1968 330 HP 383 Barracuda is absolutely NOT a one-off, and has no relevance to odd builds.
There are records and production numbers for these cars.

There are stories of dealerships unable to move winged Superbirds, and in an effort to relieve themselves of toxic assets, having them de-nosed, and/or de-winged.

That could be an explanation of a 440-4 1970 RR.

If that were the case, the rear window would be the SB window with the diamond corner fillers.

That is a much more plausible scenario than a one-off, special order, or factory mistake car.
 
Believe it or not some people would not have bought a 6 pack car. Remove the 6 pack and install a single 4 and out the door.
 
If it was a RM23 car with a U code it might have been a dealer conversion from a superbird to a roadrunner to get it off of the lot. Otherwise, like they said it might have been a GTX.
 
There was NO SUCH MODEL OR OPTION AVAILABLE, period. 70 Road Runner, non-Superbird, only available 383, 440+6, Hemi. That's it.
 
70 RR with a 440 4 bbl would be a GTX

Which is why it wasn’t offered.

It would be dumb to offer the 440-4 in a RR when it was standard in the GTX. You’d be eating into your own sales and the price difference would be minimal.

Good point. But if the cars on the lot and someone wants it but just not the way it sits. Just what happens? No sales and you continue paying to have it in inventory or mod it and make the customer happy.
Happy customers sell cars. That how one buys a 70 RR 440-4 in 1970.
