Drag Strip tips and advice needed.

I would say make sure all of your mechanical issues are fixed first, then:
1. Make sure the chassis is tuned correctly and is getting good weight transfer and it leaves straight and level and not twisted to the drivers side. Without knowing your setup I can't tell you what to change there. I can tell you that you need at least 5" of front end travel or it probably won't hook right. You may have to adjust ride height all the way down to the bump stops in front to make this happen if you still have a torsion bar front end.
hopefully you have adjustable shocks at least on the rear, if not that is a quick swap out. Remember, with a stock leaf spring car the back end will raise up as it leaves the line! You can get mono leaf racing springs but they also require CalTrac bars and that stuff isn't cheap.
Get the front end aligned for drag racing, as much positive camber as you can get and 0 toe in. See if they will let you sit in the car when they do it.
2. Once the chassis is tuned, go to fuel. Check those datalogs for A/F ratio lean or rich spikes or areas.
Get the fuel adjusted to where it runs the same 60', 330, etc. then you can start to experiment with other stuff. Don't try to get your best ET right now, just try to get a consistent ET and the motor isn't too lean. Consistent is more important than fast at this point. Once you've got that, then you can try:
3. Timing advance-give it 2 more degrees and check results. If you have improvement, give it 1 more degree and keep doing this until there is no difference, then back it off 1 degree and call it good.
4. Fuel-since you were already consistent by this point, try adding fuel to lower WOT AFR and see if the car likes it. If it doesn't I would be VERY careful about taking fuel out. If you do, do it VERY gradually and check those datalogs for overly lean. If you have it a little rich you might lose a few hundredths in your ET but it will be more consistent.
5. Shift point- experiment with higher rpm shifts and check for results.
Now the car should be fast AND consistent. Now you have to get the driver consistent:

You need to work on reaction time. If you are racing 1/4 mile you need to get that down below .05 consistently. If 1/8 mile .02 or better. There are many videos on how to accomplish that, they all involve having a lot of seat time.
Assuming you will be bracket racing:
Learn about breaking out and how to avoid it, racing the stripe, getting a good dial in, what to do when the other guy red lights and burnout procedure. Find what works for you. You will also discover that your reaction times might be quicker after dark which will cause you to go red. If that happens there are videos about what to do about that.
Search for American Bracket Racer on youtube. This guy wins a lot and has pretty good procedures on how to bracket race and win. He races a Chevy but his dad races a Mopar.
