Since no one has mentioned this: have you double checked to make sure your carb is opening all the way?

Yes sir I'll check again but I think it's good.
70cuda, I'll give it try. Honestly, the MSD pods intimidate me. There are like thousands of combinations.
As far as the TC cannot justify spending more money on it- for now I'm stuck with it.

i dont understand the responses saying that that car needs a bigger carb. it runs pretty much what it should in my humble opinion,might run alitle better times given more time and practice but look at the camspecs and you will understand the lack of mph lift isnt everything duration is the reason that engine wont make alot of HP.
more gear and converter would help some but a bigger carb wont do much if anything.
x3.
If the response is "there's too many combinations" in terms of tuning the ignition - then my impression is the OP is not able to tune to get the best possible reuslt. For bolted together and mildly tweaked I'd say it's deaed on. That cam's way small IMO. I'd like to see another 8-10° of duration @ .050 and IMO the ignition and then carb need serious tuning.
Well, art is art, isn't it? Still, on the other hand, water is water! And east is east and west is west and if you take cranberries and stew them like applesauce they taste much more like prunes than rhubarb does. Now, uh... Now you tell me what you know.

First off, how many passes did you make? What were the weather conditions? Humidity and headwind make a huge difference on a little motor in a big car.
IMHO, your converter/tire/gear combo suck for that camshaft.
It's easy to get discouraged your first time out. Go out in a little better weather, launch a little better, and you will probably get in the high 13's the way it sits.

Lots of apples to oranges comparisons about the weight. Yeah my '67 Satellite weighs 3,600 pounds but that's not an early '70s Charger either.
I still say it is closer to 4,000 pounds than 3,600 pounds but there's only one way to find out which wouldn't be a bad idea so the OP knows what he's dealing with and if his ET is really off or not.
I did find this in the archives:
"My '71 Charger is 3,850, and that is with the A/C removed and aluminum heads, intake, and waterpump housing. Best way to find out is to just weigh it."

not bad. what did you think you were going to run? more convert and more gear and you'd be in the 13's easy.
Thought the car would be right at 14.00. The disappointment was the speed through the traps. Thought it would be closer to 100 than 90.
I don't think you have enough motor for 100. Maybe with more gear. I can see you picking up a few mph in tuning/driving.

What's the compression ratio? A low compression can make an engine lazy.
The AFB is a great carb for the street. A Holley is a better carb for the track. You said this is a street car so stick with what you've got.
Lower rear gears would help. That A500 would pull a 3.91 nicely on the highway. Find out what the power band of the cam is supposed to be and get the rear gears that would put you above the low rpm point at 60 mph in OD.
I'd leave the converter alone with this being a street car.
We are brothers and sisters doing time on the planet for better or worse. I'll take the better, if you don't mind.

Obviously I didn't do my homework on the TC. This Hughes 2500 seems a little loose on the street but that could be a symptom of the tall tires as well. Options looked limited on a builder for the converter who could include lockup.
The 3.55 gears are what I had in the car before the A500 and 5.9. The car originally had 2.76s.
There are truck scales here at work and I'll use them as soon as possible just for the information.
As far as compression, with the RHS X heads the compression was estimated at 9.5 by Hughes Engines. The KB pistons were 0.017" above deck when put together.
Don't blame Hughes for the cam, my request was for a bottom end "torquey" cam.
