Winter Itch. I need a project. $1000 or so to start. WWYD???

Many have followed my build, progress, failures, learning opportunities and fun for all.
My 73 scamp has a 512 ci motor that has much potential but was lacking in performance. I fixed the cam timing, the valve lash error. changed rocker arm ratios, tuned the EFI, installed a HVH super sucker. The car is running well and is ready to go to the drag strip. BUT.....

I have a few months to go before I can do any drag strip time, or even go out very much as there is snow everywhere.

So I am considering a couple projects. Only have time and $ for 1.

1. New torque converter. Mine is a 3000 stall hughes off the shelf. I know that it is not great for racing and many have said that newer high stall torque converters are street friendly. A custom one would perk up the performance. Option 1...

2. I have Competition engineering drag shocks all around with PST 1.03 torsion bars. I just bought some 892,893 torsion bars. I want to upgrade my shocks. Both for performance at the track and for adjustability for street and strip use. Double adjustable shocks are a must so I can have the best of both worlds at the turn of a button or 2. Option 2

3... Less sexy but probably needed. sub frame connectors and torque boxes added. Option3

4. Future may need roll cage and 5-6 point restraints.

Can you change a torque converter without pulling the motor with a 4 post lift?
