How's it going folks. I am new to the website and learning about mopars basically. I'm 18 and finished turning my 80' malibu in a street-strip car and really wanted a mopar (blame dad for that lol, 67 Dart GTS). Well I scored big and found the mopar I've always wanted that was taken off the road in 77'. This RM23 roadrunner is origionally a california car and is basically rust free and I talked the guy down from 10k to 7.5k. Has numbers matching 383 4 speed and the car is origional to the point of having the factory exhaust. What I'm trying to figure out is the differences and specs between a regular 383 and the "N" code HP 383. Mine just so happens to be the "N" code. Another question I have is how often did 71' roadrunners that had the 383 4 speed come with AC? This car has the AC as well. Finally, this car has what I believed is called a Dictephone (cassette recorder) and had the black bikini vinyl top, origional color curious yellow. Are these options rare on roadrunners?

 

its "dictAphone" which is very rare. dictaphone was offerd by dealer only and REAL hard to get a real number for you. ac was i beleive a factory opt, in that year. my decode book only goes to 69. so give the other guys all the vin numbers and im sure one of them or more can give you what you want

 

i wast trying to be mean or such at all, sorry if i came off that way, finding a decode book i got mine at a local parts store they had to order it. you are correct it to decode the car, i got mine in like 95-96 and want to say i paid 30 for it then?

 

I guess there was a bit of a difference between the reg 383 and the HP 383. There's just a lot of things on this car that shows that it was special ordered and not part of a bulk order made by the dealerships. Case and point, its a 4 speed with the bucket seats, console, etc. but has AC and has a Clock instead of the RPM Gauge. I'm not sure how rare the bikini vinyl top is either. But with the options this thing has, along with the dictAphone, I believe the origional owner was a doctor or something along those lines. He wanted to look badass in this thing with all the racing options but at the same time have the lucturies such as the AC, vinyl top, etc. As we all know, these things ordered in bulk were nothing but bare bone cars, and if any muscle car guy from back then ordered one of these, he wouldn't want the AC or other luxuries.
Unfortunately, this car did have the build sheet but a rat or mouse made a home underneath the back seat and made some nesting out of it. I saved whatever scraps were legible. Here's the fender tag codes:

first 7 vin # RM23N1G

V8X 26 END
M21 N41 N97 R36 V21
C55 G11 G36 H51 J45 L31
V4X U A01 A87 B11 C16
GY3 M6X9 TX9 610 040964
E65 D21 RM23 N1G

 

Yeah its good to know there's young guns out there that haven't betrayed us for rice burners. Good luck with your satellite!

 

They put more than one build sheet in a car? I found the one in the back but the mouse got to it. I didn't know they put more than on in a car.

 

My dad didn't know that cause he always thought these mopars only had one, but i'm hearing from multiple people to check the back bench seat (did that already), both front buckets, under the carpet, behind the glove box, etc.

 

Well I'm heading out to the car to definately do some searching. I love these old cars, they turn out to be oversized treasure chests.

 

Well guys that's a negative on a second build sheet. I checked both bucket seat bottom cushions and backs, behind the glove box, under the dash, and under the shifter console. The only place I haven't check is underneath the carpet, which I would be surprised if they actually put one under the carpet.

 

i would help you decode it but my book only covers 1960-69 =+( sorry somtimes they put the build sheet abouve the gas tank. seen a 72 charger like that and a 73 challanger. wish i could help you. i think chally can decode that for ya.

 

Nah I pulled that gas tank already a couple times. I thought the build sheet above the gas tank was a chevy thing (even though my 80 malibu didn't have one)

 

Thanks polaradude. Sorry bout not responding right away. Came down with the flu the past couple days and haven't rolled out of bed to get on the computer.
