i must be completely missing something ?!?

I need to throw 5-8k at the suspension?

No, you need too tune the suspension you have!
OOOORRRRR $700 on a dual quad nitrous kit ?
NO, motor has more power then then chassis, and the chassis, let you down again!

I'm not the best one to teach you that. as for 1, i haven't made enough HP to over ride stock suspension W/ 20 plus years on my old SS Spring.

I have bought a book on chassis tuning and modifying. Even though i haven't got a full grasp of the Math, i'm learning. In the book it talks about Racers, in general, and how few know how to set up a chassis, street...street/strip or full on tube chassis. He asks a question. "How many Engine book are out there............How many transmission books........ and how many CHASSIS Books"!!!!! Most build a eng, for a set ET(my self included) and never get the full potential, because the car is a full package and the eng is only part of it.

Ok, now with that said, here is an amateur opinion. fuel is fine, for now. Not to lean to burn a piston and not to rich to cause a plug to miss fire.

First, Clamp the **** out of the front segment........ok ok when i say clamp it i don't mean the clamps that are holding the leafs together. A clamp made from a strap of steel with two hold drilled in it. Bolts and lock nuts go on either side of leaf/s causing a sandwich to the leafs.
If you have two leafs below the main leaf, in front of the axle, clamp them both.
Stick shift cars are extremely hard on any chassis, take a real good look at the front segment. If there is ANY SIGN! That the main leaf is flat or bending in the opposite direction, Clamp it there as well!
They can be made out of mild steel but need to be 1/4" thick X 1-5/8" X 4-3/8". bolt hole spacing aprox 3-1/8". 1/2 fine thread bolts,2-1/2" long. (grade 5 is good enough). This is spec i got off of a old MMP clamp, that i will us to build new one for my car! After i get a few other thing done on my car.

STARTING LINE TECHNIQUE​
With a stick you have a line lock right?
How high of a rpm can you leave the line with out smoking the clutch or smoking the tires.( i say smoke the tires because a little tire slip off the line may be beneficial. I'm taking about clutch or tires.(tires are easier to replace) 60' times will answer your questions.
I just re read you first post.......If you are going to keep the "traction bars" make sure they land on the spring eye! if not your leaf is bent already. make sure you traction bar is touching the eye.(race only) Traction bar has to be constructed to withstand the abuse with out flexing or bending​

And for the record my 60' suck because i have a auto instead of a stick and my torque converter stalls around 3000 and i need something in the 4500 stall area( big $$$$) so i do the little thing while i save.

Hope i haven't put you to sleep. THE END!:D......:burnout:
now thats some good stuff i can bight into ! Thank you . ..
