New to drag racing. Need advice.

The clamps on the rear sections of the springs, if SS springs, are no bueno in most EVERY case.

Tune first, get it so it snaps off idle then worry about the rest of it.

Those inboard boxes look like a chicken shitting molten metal installed them... :)
That's easy to fix as you have the tools. That car could be capable of 10's chassis wise. Spending money is not the approach I would take.
