Get my car to launch better...

Thanks everyone for your inputs. Here's my plan:

Set the correct pinion snubber height, reinforce floor pan
Measure rear shocks and make sure I have at least 28" extended
Put battery in trunk
Install subframe connectors
Install rev limiter - I'm thinking about the mallory hyfire ignition
Practice 2nd gear burnouts using 684mulas' technique
If I can't get his technique to work - install a line lock
If still no luck after all that maybe worth looking at slicks

Anything else anybody think I'm missing? Would drag shocks be a waste of money for my power level?
