what am i doing wrong?

I believe that's flywheel HP... But keep in mind, that's not the correct head flow numbers, probably the wrong cam specs (LSA, etc). I'll work on getting it closer to real-world later on, after I put my kid to bed and I can work undisturbed.
 
Mikel the LSA on that cam should be 110. That seems to be what Comp favors
 
Ok, I got your Dyno sheet. I plugged those numbers into Desktop Drag. It says the shift point should be 6300, launch at 3000. Redline is 6500.

60: 1.865 @ 35
330: 5.309 @ 70
660: 8.098 @ 89
1000: 10.507 @ 102
1320: 12.541 @ 111

That's "typical" track conditions (60% RH, 800 ft, 75F)

I can't quite match your dyno sheet with Desktop Dyno. If I had your head flow numbers I could. The stock Edelbrock flow numbers are too low, and the ported numbers I have (Indy) are too high.
 
i can't thank you enough for your time, and conclusion.
bottom line is its me.
next up a trailer. then i'm going for it.
thank you mikel,and thank you all for your input,

You just need to work with the car to whittle down the ETs. Raise your launch RPM, raise your shift points a little at a time and see what happens. When you slow down, back up.

My first run with my car was a 15.991 @ 87.70 MPH with a 2.595 60'.

Now it runs 12.217 @ 111.04 with a 1.829 60'. Granted, I changed the motor (went from a 318 to a 360), but I also made signifigant improvements by making changes to my driving style.
 
I think we're missing something here.

I'm assuming the dyno results are from an engine dyno, not chassis.

That said, what is different now that your in the car?

1)air quality? What are the under hood temps? Are your hood scoops funtional, or just for show?

2)fuel system.? Are you using the same one> Perhaps your losing fuel pressure? A friend of mine had problems with a car running mid 13's that should have run 12's. Only took one pass down the track with a fuel pressure gauge to find out why.

Pressure dropped to 0 by 1/8 mile. No miss, no stumble.

Upgraded the fuel system, and brought his et down.7 with no other mods.

Just food for thought...
 
Is the intake holding it back?? That was a good dual plane in it's day but a performer RPM may work better with your heads and cam choice.
 
fuel delivery system has been upgraded. under hood temp doesn't seem bad. don't know of any dart, duster with these scoops that were ever directly hooked up.(correct me if wrong, and supply how). also intake has been opened up too improve flow.
 
All I'm saying, is that your dyno sheet shows that your motor makes around 400 hp, while your time slip shows something much less.

Something must not be right now that it's in the car, or something in the combo, doesn't agree with with the application.

At a glance, it all seems to be right, which makes it more puzzeling.
 
NOT REALLY . AT THIS POINT I'M THE PROBLEM , NOT BRINGING THE REVS UP TO WHERE I SHOULD OF. NEXT TIME OUT I'M BRINGING UP THE REVS AT LAUNCH, AND SHIFT POINTS. IF IT DOESN'T HAPPEN THEN , THEN I WOULD AGREE. UNTIL THEN ITS ME BABYING THE CAR. SO MUCH CASH IN CAR I'M SCARED OF BREAKING IT. WELL PARTY'S NOT OVER , ITS ABOUT TOO BEGIN. :D
 
I dont think the intake is the problem. The LD340 is still a great dual plane. My buddy ran 11.80s with one in his 72 Cuda.
