Maybe, but that's not the big issue. The big problem is the 93.5 trap. A 2.02 60 can produce ETs in the low to mid 13's pretty easy, IF the top end is there.
OP: you're not creating the HP you should. It could be the tune, or that carter carb, but something is holding back on the top end.

Just reread the post needs fuel work and a better carb!

Ignition may need refining too.

35 total is a pretty useless number. What's the split if it has an advance curve.

Definitely lacking MPH. Carb... yuk!

Agreed...MPH number is the true measure of power. I had a bad launch and ran a 2.0 sixty foot time that still netted the same 107 MPH I did with a 1.7 sixty foot time. But my ET was a half second slower.

It might not be in the cards yet, but one day I'd call a quality converter company (PTC, Dynamic) and get one matched to your combo. A good converter isn't cheap, but makes such a difference.

Tuning the carb you already have will help tremendously. (I run a 750 Holley DP on my street/strip car and love it.) That relatively low MPH to me shows a possible fuel delivery issue.

What kind of tires are you running? Drag radials?

Hmmmm. If you are a typical hobbyist and just took it to the track the first time, I think that is pretty good. That car/engine combo from the factory was a high 15 second deal. Do you know what the car weighs?

Unless you have done this before, it is hard to put it together, go to the track, and expect it to be near perfect. I would guess that you could get it well into the 13s at 96 mph with tuning, trialing and several more track visits.

Just noticed the tire size. Put a smaller tire on it. That alone will probably put you at 14.0 and 95 mph.

Takes about 230-240rwhp to move 3900# to those times/mph.

It's missing a BUNCH!

I disagree. He probably has an honest 290 flywheel hp. I would not really expect more than 320, maybe 330 out of it.

OK, where to begin. Everyone's replies are very thought provoking.
Car weight- 3600#?
Tires are Toyo Proxes mounted on 18x10s
The TC was picked because I needed a LU for an A500. This is first and foremost a cruiser and long hauler but needs to perform to its potential
Switched out Carter for Eddy 1411 and it was way worse- put the Carter back on
Thought the car ran good, driver could have left the line harder but it wasn't horrible, expected low 14s but hoped for high 13s
A few 1/4 mile passes before with best previous experience was a '01 Firehawk 6 speed that went 13.05 @ 106 mph.
Seeing a common thread in the replies

That's 360 w/stock heads and xe256-268 hyd territory.

That engine should be making an honest high 3's easily. RHS headed 360's with 9.5:1 and xe275hl will make 420's+.

The tune up, fuel delivery, something is way off, IMO. 3600# only makes it look worse.

I would try 30 and 32 degrees total timing and see if that helps the MPH, all the SB with iron heads that I have helped tuned like it I have absolutely no experience with the heads your running so if you have treid 30 and 32 and your motors likes 35 please let us know, I'm sure there are more than one other SB Mopar on here are using them

For what it's worth...

My combo

5.9L magnum.
Stock heads
2bbl M1 intake
222/228 107LSA, .544 lift
4000lb truck
Stick shift 3.92 gears, 27" tires, stick shift

2.2-2.3 60'
14.2 @ 99 mph

Your combo has a slightly smaller cam, but better flowing heads. You have a lot more potential with more tuning.

Since when does a 72 Charger only weigh 3600 LBS?

Not bad.
My 64 valiant vert did 14.5 with a stock 318 4bbl and dual exhaust with a 4 speed. Had a huge vacuum leak though and hard to keep the skinny tires from spinning.

Only a guess based on other cars I have actually weighed in the past. Apparently my guess is off.
FWIW A few weeks ago the car had a short bog or stall at initiall WOT but would bark the big tires in second. Remedy was advance timing a little more, change the pod settings in the dist and eventually the stall went away and so did the tire bark. Bogging is not an option but maybe 32* would be worth a try again. Gotta find a good carb combo it sounds like.

converter can be a weak link...need a good one to transfer power...and suspension is whatI'd look at next. Not bad numbers

Undo those changes to get your '2nd gear bark' back

Then tune out the bog with the carb pump shot. It's probably a lean slot and needs more gas
